PREFACE This volume contains data on morphology, ecology, and chorology of feral species and subspecies of 31 families of flowering plants. The families have been arranged essentially according to the Engler system. Conforming to the latest views (Takhtadzhyan, Sistema magnoliofitov [System of Magnoliophyta] 1987), some families have, however, been subdivided into some smaller families. Thus, family Biebersteiniaceae has been separated from family Geraniaceae; family Zygophyllaceae s.l. is represented in Siberia by 4 smaller (in volume) families: Zygophyllaceae s. str., Rutaceae, Nitrariaceae, and Peganaceae. Much of the work has been carried out by the colleagues at the laboratory of taxonomy of higher plants and florogenetics of the Central Siberian Botanical Garden, Siberian Division, Russian Academy of Sciences, during 1991-1995, but the largest family Apiaceae or Umbelliferae (92 species and subspecies of 50 genera) has been prepared by M.G. Pimenov of the Botanical Garden of M.V. Lomonosov Moscow State University, who is highly knowledgeable about this family. As a result, this critical study has provided the specific characteristics of taxonomy and chorology of 299 species and subspecies belonging to 101 genera including 6 taxa that are new for science and their diagnosis in Latin. Apart from the Novosibirsk collection of M.G. Popov Herbarium and the General Herbarium of the Central Siberian Botanical Garden, Siberian Division, Russian Academy of Sciences, the collections of the following leading botanical organizations of Russia have been studied to arrive at a more complete picture of the distribution of species and subspecies: Herbarium of V.L. Komarov Botanical Institute, Russian Academy of Sciences (curator: D.V. Gel’tman), P.N. Krylov Herbarium of Tomsk State University (curator: A.V. Polozhii), and D.P. Syreishchikov Herbarium of M.V. Lomonosov Moscow State University (curator: LA. Gubanov).
VI The drawings given in this volume are original and have been prepared for the Monograph of Siberian Species of Genus Euphorbia by K.S. Baikov. Unfortunately, financial restraints did not permit increasing the number of illustrations. L.Z. Lukmanova rendered much assistance in the preparation of the manuscript. The compilers of the volume express sincere gratitude to all the above colleagues. The study was supported by the financial assistance of the Russian Fund for Basic Research (grant 93-04-08000). G.A.

Altay; nor. boundary of distribution range runs in the territory of Altay mountain range. References to the growth of this species in Krasnoyarsk region, in all probability, pertain to white-flowered races of G. pratense since the pubescence of stems in them is distant, not appressed, as in type in specimens. 2.

P- Stems (10) 15-80 cm tall, erect, covered with very short appressed replicated hairs, quite often subglabrous in lower portion. Radical leaves long-petiolate, their blades orbicular reniform in profile, 3-15 cm broad, 2-12 cm long, divided up to 2/3-7/8 of their length into 5-7 (upper into 3) broad-rhombic or oblong-ovate lobes, in turn rather shallowly pinnatifid or large- toothed, appressed-pilose on upper surface; pubescence very
9 14 sparse beneath, mainly along veins. Peduncles with (1) 2-3 each somewhat open (campanulate) flowers on erect glandular-pilose stems. Sepals elliptical or lanceolate, with short (up to 1.5 mm) awn. Petals (7) 10-15 (17) mm long, oblong-obovate to broad- ovate, erinite, white, pale lilac or pale violet, sometimes lilac, with dark-colored nerves along margin and inside. Anther filaments in bisexual flowers gradually enlarged toward base, puberulent in lower portion along margin and their outer surface, slightly shorter than petals; anther filaments in small (female) flowers 1/2 of sepals, with underdeveloped anthers. On Putoran plateau (Talnakh lake), 2n = 26; in West. Sayan (upper course of Kashkaret river), East. Sayan (Tunkinsk mountain range), Fore- baikal (Turkulik river, upper courses of Shumilikha river), and Stanovoi upland (Severo-Muisk mountain range) 28. In larch, mixed, and pine forests, forest borders, glades, along valley meadows, scrubs; ascends into high mountains, being common in alpine and subalpine meadows, in sparse forests, dwarf birch thickets, and grassy tundras at foot of bald peaks. West. Sib.: TYU—Yam, KE, AL—Go. Cen. Sib.: KR—Ta, Pu, Tn, Kha, Ve, TU. East. Sib.: IR—An, Pr, BU—Se, Yuzh, Chi— Ka, Shi (Maloe Sokhondo bald peak), YAK—Vi, Al.—Arctic Europe, Polar Ural, Mid. Asia, West. China, Nor. Mongolia. Described from Perm province territory (on brook at Martaisk Kamen’). Highly variable species. Size and color of flowers, degree and type of laciniation of leaf blades vary. In southern Mongolian parts of Tuva and Altay, plants have stems with quite compact pubescence of short replicate hairs all along their length. In dark coniferous forests of Kuznetsk Ala Tau, geranium is prominent with large sizes of stems and leaves; further, leaves are rather shallowly divided, with almost overlapping lobes. In alpine regions of Sayan, specially in East. Sayan and on Baikal coast, plants with very large, lilac or lilac-tinted flowers are common. Leaves divided very deeply, quite often up to 7/8 of their radius. On Putoran plateau, Stanovoi upland, and in mountains of Yakutia, plants are small-sized because of severe climatic conditions; leaf blades deeply divided into oblong-ovate,, distinctly separated lobes (somewhat resembling leaves of open anemones); flowers are perceptibly larger (petals 14-17 mm long) and almost invariably with faint lilac or violet shade; inflorescence impoverished. In low-mountain regions of Siberia, plants almost invariably with many white, small flowers, leaves deeply divided with contiguous rhombic or broad-ovate cuspidate lobes and stems subglabrous in lower portion, and glandular-pilose in inflorescence.

Described from steppes between Tomsk and Krasnoyarsk. In Fl. Rossica (1841, 1), while characterizing G. pseudosibiricum described by J. Mayer in 1786, K.F. Ledebur cites G. bifolium and G. coeruleum announced later by E. Patrin (Prodr. 1824, 1) and also his own species G. laetum published in 1830 as synonyms. Later, L.P. Sergievskaya (Sist. zam. Tomsk, un-ta [Notes on Taxonomy at Tomsk State University] 1934, 1) recognizes one more species G. asiaticum in the lowlands of Western Siberia. Investigations of E.G. Bobrov (Fl. SSSR, 1949, 14) established that the species identified by L.P. Sergievskaya
14 is identical to Patrin’s G. bifolium. In our opinion, Ledebur’s announcement was without adequate basis and his species G. laetum was a product of hybridization of alpine G. krylovii and predominantly low-mountain G. pseudosibiricum. Only in Altay, where the distribution range of G. laetum is essentially concentrated and alpine open associations are in contact with meadow- steppe and steppe associations, conditions exist for the hybridization of parent species G. krylovii and G. pseudosibiricum and for the formation of an ecological niche for the resultant daughter species G. laetum. Elsewhere in Siberia, alpine meadowy associations are separated from meadows and steppes of forest-steppe and lower forest belts by a more or less broad taiga strip (thus excluding contact of the ranges of the above-mentioned parent species) and G. laetum is not found there. Only in Baikal (where G. albiflorum sometimes descends up to the coast because of the cooling effect of the lake), specimens of G. pseudosibiricum are occasionally found, their pedicels bearing rather few glandular hairs but such plants are very rare and grow together with G. pseudosibiricum', these can be treated as G. pseudosibiricum var. subuschkanense (M. Popov) Peschkova, comb, nova = G. coeruleum var. subuschkanense M. Popov (in Popov and Busik, Konsp. fl. pober oz. Baikal [Conspectus of Flora on Baikal Lake Coast] 1966, 213). These cannot be treated as G. laetum (in which flowers are bright violet, awn of sepals is longer, not only pedicels but quite often even peduncles have glandular hairs), although there is close resemblance between the 2 in the presence of glandular pubescence on pedicels. In G. coeruleum Patrin, as emerging from the protologue, stamens are half of calyx. Plants characterized by these features are quite common in Siberian territory, specially in Eastern Siberia. Evidently, this provided justification to M. Popov to regard that G. coeruleum grew in Central Siberia (according to him, this region includes Buryatia, Irkutsk, and Chitin provinces). As a matter of fact, as pointed out by D.A. Webb and I.K. Ferguson (Fl. Europ., 1968, 2), plants exclusively with female flowers are quite often found among G. pseudosibiricum. Stamens in them are shortened, half of calyx, their filaments enlarged for almost 3/4 of their length, anthers small, underdeveloped. Petals 6-7 mm long, slightly longer than calyx. Evidently, it was such plants that were described as G. coeruleum Patrin. L.P. Sergievskaya (1934, op. cit.) treated them as G. pseudosibiricum var. parviflorum Serg. They grow quite often together with plants of G. pseudosibiricum and bear completely normal bisexual flowers. Bisexual as well as only female flowers can often be found on the same plant. There is therefore no justification to separate G. coeruleum and it should be
15 left with the priority name G. pseudosibiricum. Thus, K. Ledebur combined 3 undoubtedly very close but totally independent races under G. pseudosibiricum J. Mayer: G. bifolium common in the plains of southern West. Siberia and Krasnoyarsk region, G. laetum characteristic of Gorn. Altay and contiguous sections, and G. pseudosibiricum extensively distributed in the southern forest- steppe and forest-covered foothills of Siberia, from Urals in the west to Yablonovyi mountain range in the east. 18 15.

E. ambukensis described recently from West., Sayan (Stepanov, Florogen, analis, 1994) belongs to this variety. Unfortunately, the type of E. ambukensis preserved in the Herbarium of Central Siberian Botanical Garden, does not show the regenerative structure (cyathium

49 absent), and hence it is impossible to evaluate the characteristics of cyathium and fruits. Such specimens with undeveloped regenerative structures are found among other species too. Further, their morphology may differ considerably from that of normally grown plants. The doubt arises if regma of E. ambukensis is fine-tuberculate (shown in protologue) since, in E. altaica, it is covered by distinctly visible pectinate outgrowths. An analysis of intraspecific variability of E. altaica did not permit distinct separation of Sayan from Altay plants and establish their independent form. Features characteristic of E. altaica var. sajanensis are sometimes found even in Altay plants and subjected to ecological modification. 3. E, caesia Kar. et Kir. 1841, Enum. Pl. Fl.

Originally, this species was described by K. Ledebur based on the unique collection of R. Kruze from the vicinity of Irkutsk. A distinctive feature of E. discolor as cited by Ledebur is the double color of leaves. Later, the authors of Siberian flora began treating this species in a very broad sense, mainly as a result of the views of Ya.I. Prokhanov and placed in it most Siberian plants identified before as E. esula. A. precise description of the morphological boundaries of E. esula is impeded by the wide variability of many characteristics of this assorted species (in a broad sense) as well as by the absence of strict application of this name to the type since it has been applied to 3 different herbarium specimens of the collection of Linnaean types. 7. E. esula L. s. 1. 1753, Sp. PL: 461—E. discolor auct., non Ledeb.—E. gmelinii Steudel—E. maackii auct., non Meinsh. Perennial, 30-90 cm tall herbs, glabrous or sometimes pubescent.

Leaves 3-6.5 cm long, 6-8 times longer than their breadth, lanceolate or linear-lanceolate, sometimes narrow-obovate, and then attenuated downward into a short petiole. Inflorescence umbellate- paniculate: rays 1-3 times branched, rays of umbel (6) 8-13, 1-6 under umbel. Bracts irregular-rhomboid, up to semicircular, their bases usually not overlying each other. Nectar glands short- bicornuate, greenish brown. Regma 2.5-3 mm long, truncated- globose, deeply trisulcate, scabrous on back of lobes. Styles 1.2-1.8 mm long, connate below roughly for 1/6 of length, split upward for 1/3. Seeds 2-2.3 mm long, ovate, brown or silver- grey, up to whitish, with distinctly visible depressed caruncle.

The present treatment has clearly established the boundaries of E. discolor and, as a result, many Siberian plants were distinguished from E. esula. In Siberia, E. esula is represented by several varieties differing in the breadth of leaves and height of plants. In Yakutia, var. latifolia Ledeb. with leaves up to 12 mm broad is most common while xeromorphic var. cyparissioides Boiss. with much lower, profusely branched stems and narrow, sublinear leaves is widespread in southern Chitin province and Buryatia. 8.

54 therefore proposed a new name for it without diagnosis (E. pallasii) but perpetuated an error by referring to the first description and crediting authorship of the species to P.

62 Plant with terminal umbellate inflorescence and lateral vegetative branches (specimen 630.59 of the Herbarium of Linnaean Types) should be regarded as type of E. pilosa L. These characteristics are absent in the Siberian plants identified as E. pilosa L.: these are characterized by corymbose inflorescence (upper leaves not aggregated into false whorl which feature is particularly well perceived in the period of fruiting) and simple (without lateral branches) stems. The description of Siberian plants was given by C. Linnaeus (Sp. Pl. 1753) under the diagnosis of the species as a synonym. These plants were later described 52 as E. lutescens. The recently described subsp. ojensis from the subalpine meadows of Kulumyssk mountain range (West. Sayan) (Stepanov, Florogen. Analiz, 1994) does not have an exclusive distribution range and represents an ecological form of E. lutescens, and is related to it through a continuous series of intermediates. 18.

This polymorphous species is represented in Siberia by 5 morphological forms (including E. nigrum s. str.) which are often treated as independent species. According to N.N. Tzvelev (Arct. fl. SSSR, 1980, 8), they are distinguished by combinations of 2 basic features: flowers bisexual or unisexual,
74 young shoots covered with glandular hairs and woolly pubescence of very long flexuose hairs or pubescence with only glandular hairs. The leaf shape, extent of leaf deflection from stem, and color of shoots serve as additional diagnostic characteristics. The distribution of these forms in Siberia was analyzed for purposes of demarcating the ranges of each of them. Only the form corresponding to E. hermaphroditum is more or less confined to the north of Tyumen province but forms corresponding to E. subholarcticum and E. nigrum s. str. are also found there. Rest of forms are found in the different regions of Siberia without any strict pattern. N.N. Tzvelev (1980, l.c.) distinctly differentiated E. sibiricum from the other species on the basis of the presence of woolly pubescence on young shoots. However, in this monograph “Rod Empertum” [Genus Empertum], V.N. Vasil’ev (1961) pointed out that such pubescence is found only sometimes in this species (in Irkutsk province, Buryatia, and Chitin provinces, from with woolly pubescence on young shoots predominates, but plants without such pubescence are also found sometimes in the same locality). The lone more or less distinctive difference of the form corresponding to E. sibiricum is the perceptibly deflexed leaf. However, this characteristic is associated through intermediates with E. subholarcticum which is also distributed in that area. According to V.N. Vasil’ev, the most significant difference of E. subholarcticum from E. sibiricum is the enlargement of leaf toward lower part and a more distinct isolation of petiole (not pubescence of young shoots or bisexualism of flowers as assumed by N.N. Tzvelev). Transitions between these “species” with 61 respect to this feature also do exist. The difference of E. subholarcticum from E. nigrum s. str. and E. hermaphroditum, according to V.N. Vasil’ev, lies in more narrow leaves and long anther filaments. It is quite difficult (often impossible) to measure the length of anther filaments relative to petals and thus this characteristics requires to be studied carefully. E. subholarcticum in Siberian territory does not differ reliably from E. nigrum s. str. and E. hermaphroditum with respect to the breadth of leaf. This suggests the presence of a continuous series of variations of a single polymorphous species E. nigrum L. in Siberian territory. Family CELASTRACEAE 1. Euonymus L. 1.

West. Sib.: OM, TO, NO, KE, AL—Ba, Go. Cen. Sib.: KR— Ve (vicinity of Krasnoyarsk).—Endemic. Described from Kemerovo province (former Tomsk province). Linden found in the vicinity of Krasnoyarsk has been treated by T.N. Butorina (Tr. Gos. zapovednika “Stolby”, 1958, 2) as a special subspecies T. sibirica subsp. jenisseensis Butor., notn. nud. Later, N.V. Stepanov (Bot. zhurn. 1993, 78, 3) assigned the rank of species to it—T. nasczokinii—and gave its diagnosis, according to which this species differs from T. sibirica and T. cordata in few- flowered inflorescences, asymmetrical transversely cordate or transversely truncated leaves and lanceolate lobes of stellate stigma. Leaf blade, bark, form of crown, etc. have been traditionally used for diagnosis of wooded plants. Stigma characteristics have practically not been used in view of their high
82 variability in the vegetative season; the same applies to the pubescence of ovary and, to some extent, of fruits. Differences are noticed between species of linden in the nature of venation and pubescence of underside of leaf blade. Thus, leaf form and size vary in T. amurensis Rupr. with pubescence only at the base of blade and in T. cordata and T. sibirica with pubescence in vein corners. However, leaf form and size are subject to individual variation and require to be tested on large scale. All of this applies to linden from the vicinity of Krasnoyarsk as well: systematic collection and analysis of all characteristics are required for understanding the taxonomic rank. The name T. nasczokinii cannot be applied on the basis of formal characteristics: the name of nominal type (T. krasnojarica Stepanov, LE) does not agree with the published name (see Section 7 of International Codex of Botanical Nomenclature... 1980). However, considering the incorrectness of this name, the author of the species (Stepanov, Florogen, analiz, 1994) does not recognize it and has at present assigned the name T. cordata Miller. 67 Family MALVACEAE 1.

Sib.: TYU—Khm (Nyais river), Tb. Cen. Sib.: KR—Ve. East. Sib.: BU—Yuzh (southern bank of Baikal: Tankhoi station, Mishikha river region, along Osinovka river).—Europe. Described from Europe. H. tetrapterum has winged ribs on stem and lanceolate acute sepals, while in H. maculatum, ribs are without wings, sepals oval, rounded or somewhat serrate at tip. Judging from the description (Kashina, Opr. rast. Krasnoyarsk, kr. [Key to Plants of Krasnoyarsk Region] 1979), only H. maculatum is found in Krasnoyarsk region. According to the data of L.M. Cherepnin (Fl. yuzh. chasti Krasnoyarsk. Kr. [Flora of Southern Krasnoyarsk Region] 1963, 4), the isolated eastern section of the range of this species falls in Krasnoyarsk region 75 while much of the range lies in Europe, with the eastern boundary passing through the vicinity of Tobol’sk (Krylov, Fl. Zap. Sib. [Flora of Western Siberia] 1935, 8).

Europe, Mid. Asia, Pamir, East. Kazakhstan, Himalayas, Mongolia. Described from West. Himalayas. Map 57. A single habitat has been cited for Krasnoyarsk region: in the valley of Bol. Anzas river. One more habitat has been detected in the valley of Ona river. S.G. Gorshkova in Flora SSSR, 1949, 15, cites yet one more species for Siberia: M. squamosa Desv. The distinctive feature adopted—flower racemes terminal (M. bracteata) or lateral (M. squamosa)—cannot serve as a diagnostic characteristic since plants exclusively with lateral or terminal racemes as well as with both simultaneously have been found in nature. Some investigators (M.G. Popov, M.E. Kirpichnikov, and V.I. Kurbatskii) dispute the find of this species in Siberia. E.G. Bobrov (Bot. zhurn. 1967, 52, 71) cites eastern regions of Mid. Asia as habitat of M. squamosa. 2. M. longifolia (Willd.) Ehrenb. 1827 in Linnaea 2: 279— Tamarix longifolia Willd. 1816 in Abh. Akad. Wiss.—Berlin: 85—M. dahurica (Willd.) Ehrenb.
103 Shrubs up to 2 m tall, with cinnamonic grey bark on old shoots and yellowish green bark on young, year-olds.

Calyx 3-4 mm long, somewhat shorter than petals, lobes of calyx 82 lanceolate, enlarged toward base, acute, scarious along margin; petals pink, oblong-oval, 5-6 mm long, 2-2.5 mm broad. Ovary elongated-ovate, with capitate stigma; stamens connate for 2/3 of length. Fruit narrow capsule, dehiscent with 3 valves. Seeds small (1.2 mm long), with awn, covered from center with long white hairs. On pebbly and rocky banks of mountain rivers, ascending up to upper forest boundary. West. Sib.: AL—Go. Cen. Sib.: KR— Kha, Ve, TU. East. Sib.: IR—An, BU—Se, Yuzh (Baikal lake- class. hab.), Chi—Shi.—Mongolia. Map 58. The authors describing species M. dahurica and M. longifolia cited the following features for diagnosis: arrangement of flower racemes (lateral or terminal) and shape and size of bracts and leaves. A study of these species in the field showed that the characteristic lateral raceme or terminal raceme cannot serve as a diagnostic feature since plants exclusively with lateral or terminal raceme as well as with both simultaneously are found. The other features cited above are subject to high polymorphism and cannot serve as a basis for establishing the specific independence of M. dahurica and M. longifolia on the basis of descriptions given by Willdenov and Ehrenberg. M.G. Popov, I. Yu. Koropachinsk, and V.I. Kurbatskii also consider that these species cannot be treated as independent since they are indistinguishable based on their overall morphological features, have a common distribution range, and do not reveal differences in ecological characteristics. All these observations prompt us to treat them as synonyms.

Two live forms are known: epTgeogenetic—short-rhizomatous and rhizomatous-soboliferous. Rhizome usually multicipital, covered with remnants of brown stipules. In the lower part of stem, stipules narrow-lanceolate, brown, green above, transverse-oval, large (up to 2-3 cm long). Radical leaves long-petiolate, quite often as long as stems, cauline leaves on petioles reducing upward, and uppermost leaves subsessile. Petioles of leaves and stems pubescent with long distant hairs on one side. Leaf blades cordate, reniform, crenate and diffuse-puberulent along margin. Chasmoga- mous flowers 1.3-2 cm long growing in axils of radical leaves, some petals of these flowers oval, light violet, whitish at base; spur greenish, somewhat cuspidate. Sepals lanceolate, large, ciliate along margin and sometimes along midnerve. Cleistogamous, rarely chasmogamous flowers growing in axils of cauline leaves. Capsule oblong, on stem, dehiscent with 3 valves. Seeds pyriform, light cinnamonic, with large appendage. In birch, aspen-birch, pine forests, and sparse forests, rarely in scrubs. West.

Map 60. We did not favour the name V. brachysepala Maxim, since the characteristics cited for this species as diagnostic features are inconstant and do not conform to any geographic pattern. The characteristics of live forms also are not specific (Smirnova, Kagarlitskaya, Bot. zhurn. 1972, 57, 5). Ciliation of sepals and their length vary in the distribution range of V. brachysepala as well as of V mirabilis. The sole feature-pubescence of petioles and stems—based on which the western race V. mirabilis s. str. can be distinguished from the eastern V mirabilis subsp. subglabra, has been established by K. Ledebour. Section Rosulantes (Borbas) Zuev stat. nov. Subsect. Rosulantes Borbas 1890 in Koch. Synops Deutsch.

Described from Europe. Plants found in Siberia require thorough investigation. The indentification of microspecies is difficult due to limited herbarium material. It is quite likely that hybridization proceeded between them (Tzvqlev in Novosti sist. vyssh. rast. [Developments in the Taxonomy of Higher Plants] 1993, 29) or there was polymorphism, caused by the aquatic medium of habitation.

China, Tibet, Mongolia, Far East, Nor. America, Australia. Described from Europe. Specimens intermediate in their characteristics to H. tetraphylla belong to a special species—H. x lanceolata Retz. Botanists hold opposite views regarding the status of the latter species: some regard it as a synonym for H. tetraphylla and others for H. vulgaris; some others (Tzvelev in Arkt. fl. SSSR, 1980, 8) as an independent hybrid species. Considering the high polymorphism of H. vulgaris, it is quite possible that some of the extreme forms of this species are identified as H. lanceolata. The question of the status of the latter species has so far not been studied and we refrain from including it among the flora of Siberia. Family APIACEAE or UMBELLIFERAE* 1.

Sib.: KE, AL—Go.—Fore Urals, China. Described from China. Map 79. The identity of Siberian material with 5. giraldii described from Nor. China (Shenxi province) is not entirely reliable since the type material of S. giraldii (Giraldi, No. 5838) has evidently been lost and the characteristics stated in the protologue do not correspond to the features of plants from Kuznetsk Ala Tau and Altay (“prophylla primaria 2-5 f(oliis) basal (ibus) aequimagna vel majora et eis subconformia”). H. Wolff considered this feature as important, having regarded it as the basis of identification of specimens of section Neosanicula H. Wolff. The specimen has been attached to the description of N.N. Lashchinsky jr. under the same Sanicula altaica.

Species highly variable throughout the extent of its extensive distribution range; nature of growth, form and size of leaflets of phyllary and involucels are particularly variable. Attempts were made time and again to separate from B. triradiatum minor species-segregates or at least intraspecific taxa within its range. Recently, I.M. Krasnoborov made a comparative study of B. triradiatum s. 1. and B. americanum Coult. et Rose (Abstracts of XV Int. Bot. Cong. Tokyo, 1993: 255). He distinguishes B. arcticum (Regel) Krasnob. (from Stanovoy plateau to Sakhalin, Chukchi, and Alaska), B. ajanense (Regel) Krasnob. (from Priamur’e to Alaska), and B. triradiatum proper (alpine Siberia,
194 Sakhalin, and Kamchatka) without unfortunately citing their differences. Since these taxa in several regions are sympatric and the distribution of chromosome races with 2n = 12 and 2n = 16 does not correlate with their distribution ranges, for the time being, we have treated this species in the broad conventional sense. 16.

Differs from the next species only in the form of terminal lobes of leaves. The distribution range of C. longifolium is entirely covered in the extensive range of C. tataricum’, the two species quite often grow in the same region. Close to the locus classicus (East. Sayan), they are somewhat distinctly differentiated and intermediate forms are not reported. On the southern bank of Baikal can, however, be found forms of C. tataricum with lobules much longer than usual and approximating C. longifolium. It is quite possible that a more thorough field investigation would reveal C. longifolium as an intraspecific taxon of C. tataricum. Many collections of C. longifolium from Yakutia have been re-identified by us as Tilingia ajanensis. 2. C. tataricum Hoffm. 1816, Gen.

We treat this species exhibiting considerable variation of morphological, caryological, and chemical characteristics in a broad sense, conforming to the Flora of USSR. Certain taxonomic problems arise in the interpretation of Baikal populations of the species found on rocky slopes as well as on lake sand. In this region, pubescence of fruits varies greatly. In the classic site for P. baicalensis (Bol. Koty settlement), fruits are moderately pubescent while fruits of typical P. sibiricus are regarded as glabrous. However, mildly pubescent fruits may be found along with glabrous fruits all over the distribution range of P. sibiricus s.l. (Popov, Spisok rast. Gerb. Fl. SSSR [Catalogue of Plants at the Herbarium of the Flora of USSR] 1955, 13; Siplivinskii, Novosti sist. vyssh. rast. [Developments in the Taxonomy of Higher Plants] 1970, 7). The difference of leaf shape pointed out by Siplivinskii between P. popovii (= P. baicalensis) and P. sibiricus s. str. simply does not exist: the latter species has the very same highly branched caudex as P. baicalensis. The number of chromosomes cited here is either erroneous or atypical for the species. The investigations carried out at the Moscow State University describe P. sibiricus as a highly polyploid species with the number that is maximum possible in the entire subfamily Apioideae. This number has not been established accurately so far. 2. P. villosus (Turcz. ex Fischer et C.A. Meyer) Ledeb. 1844, Fl. Ross. 2: 331—Libanotis villosa Turcz. ex Fischer et C.A.
