Other subfamilies of Rosaceae are dealt with in Vol. X, as they could not possibly be accommodated in the present book. The present volume includes such plants of economic importance as currants and gooseberries, pears, apples, and related genera. The wide range of species of these genera growing wild in the USSR are of interest to breeders as material for remote hybridization, selection of wildlings, and direct introduction. This material could be of great value for orchards and soft-fruit plantations in the USSR. Many rosaceous species described in this volume have yielded, or may yield in the future, a considerable number of trees and shrubs for horticultural use. Numerous species of the Saxifragaceae and Crassulaceae may likewise prove to be of interest as ornamental plants. The study of the material treated inthis volume has led tothe identification ofabcut 70 new species. In conformity with international rules, the descriptions pertaining to these species are also given in Latin. It should be noted that this volume brings the number of species up to about half the total number of higher plants of the USSR, which presumably does not exceed 14,000 species.

Herbaceous annuals or perennials, rarely undershrubs with a woody stock; leaves mostly succulent, fleshy, simple, exstipulate. Note. The family Crassulaceae numbers ca.1,500 species in 6 subfamilies and 33 genera distributed all over the globe. About 550 species in 10 genera belong to the subfamily Sedoideae. This subfamily includes most of the species of Crassulaceae occurring in the USSR (107). The Semperviroideae with ca. 85 species in4 genera are distributed throughout the Mediterranean region, the Canary and Madeira Islands. All the species growing in the USSR belong to Sempervivum. The subfamily Cotyledonoideae, with over 70 species in 6 genera, is represented in the Soviet Union by a single species of Umbilicus (subgenus Chiasto- phyllum) growing inthe Caucasian forests. The Penthoroideae, which could well be considered as a distinct family, consists of the single genus Penthorum, which is distributed in the Soviet Union and in North America. The Crassuloideae, with ca.5 genera and 300 species in tropical Africa, S. Arabia, and Madagascar, are represented in the USSR only by Tillaea. The subfamilies Kalanchoideae (ca. 230 species) and the Echeverioideae (ca. 200 species) do not occur in the USSR. Economic importance. Owing to the variety of forms and the relative ease of vegetative propagation, the Crassulaceae deserve special attention as ornamental plants suited to widely different climatic zones. Numerous * Treatment by A.G. Borisov. species are widely cultivated, such as certain species of Sempervivum and Sedum (S.sparium, S. spectabile,and many others). The cell sap of the Crassulaceae contains malic acid, traces of tartaric acid, and tannin (Hegi). Note. As they become much deformed when dry, it is essential to study the Crassulaceae in viva.

S.caucasicum Rupr.is one of the numerous geographic races of S.tectorum L. It differs from S.tectorum in its smaller size (45-60 (100)em in S.tectorum), its smaller fewer -flowered inflorescence, and longer petals. S.tectorum is a native of the mountains of central and Southern Europe and occurs in the Soviet Union in gardens or, possibly, as an escape from cultivation. S.caucasicum Rupr.is represented by a series of forms with puberulent or perfectly glabrous basal leaves.

S.globiferum is reported by Linnaeus as collected in "in Rutheno'' by S.Gmelin. Since S.Gmelin collected only in the Caucasus (the other Gmelin, Johann Georg, collected plants only in Siberia where Sempervivum does not occur) and as Linnaeus may have believed that the Caucasus could also be referred to as Russia, it is conceivable that S.globiferum p.p.(S.armenum Boiss.) was described from the Caucasus. However, Linnaeus also mentions other characters of European species which are not valid for the Caucasian species. As far as the Caucasus is concerned, S.globiferum is to be interpreted sensu stricto. *6. S.glabrifolium A. Bor. sp. nova in Addenda VIII, p. 357.

Type in Leningrad. Note. Chamisso considered Sedum dentatum Steph. in herb. from Transbaikalia as identical with the Okhotsk species. The appellation S.dentatum Steph. could not be retained, for there already existed a S.dentatum DC.in the Caucasus, therefore Chamisso was undoubtedly wrong in describing S.stephani as an Okhotsk and Transbaikalia species. R.stephani s.str. is characteristic for the Far East. A closely related species growing in Transbaikalia, R.pinnatifida A. Bor.,is differentiated by color of corolla (yellow flowers, cream-colored or whitish in R.stephani), color of leaves, longer stamens, shape of hypogynous scales, and a number of other characters.

This species is very closely related toS.spurium M.B., from which it is distinguished only by its white or pale yellow corolla, somewhat different leaf shape, and distribution area. S.oppositifolium Sims. occupies regions in the Caucasus where S.spurium does not occur. S.oppositifolium is a more xerophytic species, growing in drier regions in the E. and the S. Caucasus, while S.spurium grows mostly in the more moist N.and (partly) W. parts. In Daghestan and in the former District of Artvin, where both species occur, transitional forms with indeterminate coloration may be found (according to Grossheim). Economic importance. Widely cultivated, like S.spurium,as an ornamental plant. 28. S.involucratum M. B., Fl. taur.-cauc. I (1808) 352; Ldb., Fl. Ross. II, 1833) Boiss., Fl. Or: Il, 778; Grossh., Fl. Cauc.

A number of authors — among them Meyer, who described S.obtusifolium, later Boissier (1872), Hamet (1908), Ledebour (1844-1846) — give an incorrect description of this plant. The error consisted in overlooking a character as important as the very characteristic villous pubescence. In addition, Boissier mistakenly records the corolla as being white instead of pink. Grossheim corrected these errors in the Flora of the Caucasus. 30. S.listoniae Vis. in Inst. Sc. Venet. Mart.I (1841) 21; Boiss., Fl. Or. II, 779; Berger in Engi.u. Pr., Nat.

Caucasus: Recorded for S. Transc. — Armenia, Nakhichevan, Bezoglyban (K6nig). This indication should be verified. Gen.distr.: Bal.-As. Min. Known from Asia Minor (Bithynia, Ankara, Karya). Described from Asia Minor. Type in Venice. Note. We have no specimen from the Caucasus. A species closely related to S.obtusifolium, distinguished by narrower leaves and by glandular-pubescent inflorescence branches (Grossheim). According to Hamet, the sterile shoots of S.listoniae have semiterete instead of flat leaves and follicles are not divaricate; this species would thus be remote from S.obtusifolium, which is unlikely. Judging by the illustration of S.cariense Jaub. et Sp.,a synonym of S.listoniae, this species is closely related to S.obtusifolium C.A. M. and to S.stoloniferum Gmel. Raymond-Hamet considers S.listoniae Vis. as a synonym of S.obtusifolium C.A.M.,as wellas of S.bornmulleri Hausskn. (S.rhodanthum Bornm.), known from Mt. Deli -dag in Armenia. Subsection 2.

Gen. distr.: Poland and farther west, almost all of Europe; occurs in the Aland Islands; naturalized in some sites in England. Described from N. Europe. Type in London. Note. Many authors have considered S.sexangulare as one of the forms of S.acre (Hegi, Berger), or as its synonym; often the same illustrations were labeled both as S.xacre andas S.sexangulare (for example in Maevskii in old editions, in Syreishchikov, etc.). Judging by Linnaeus's short description,S.sexangulare can be considered as one of the ecological forms of S.acre. However, basing our decision on the work of Huber (Ge oe. )), who has seen authentic specimens from the Linnaean Herbarium, we follow the example of Praeger (1. c.) and Froderstrom Ge c.) in considering S.sexangulare L. the same as S.mite Gilib., but S.boloniense Lois.an independent species.

Asia: Dzu.-Tarb. (Dzungarian Ala-Tau), T.Sh., Pam.-Al.(Alai Range). Gen. distr.: Dzu.-Kash. (Kuldja). Described from the Dzungarian Ala-Tau. Type in Leningrad. Note. In his description of S.olgae, Regel cites only 6-merous flowers, but in fact flowers with 7 petals occur in authentic specimens; this is true also of S.umbilicoides Rgl., for which 7-merous flowers are recorded, though 6-merous flowers are not exceptional. Umbilicus alpestris Kar.et Kir. also has 6- and 7-merous flowers, but they are more united at the base thanin S.olgae and S.umbilicoides. The number of stamens (8—10) indicated by Regel for S.olgae is erroneous; this species always has a double number of stamens, viz.,12—14. Thus, these three species cannot be differentiated on the basis of the material available. The specimens collected in the Ketmen Range are distinguished by their stockiness, few flowers (often 1), and more intense color of flowers. Certain specimens from the Kirghiz Ala-Tau (collections of Massagetov and Massal'skii) andfrom the Beishmunak natural boundary area (collections of Taranenko) are distinguished by linear-lanceolate leaves. 16.

Engl. et Irmsch. with many varieties and forms for W. Europe; these differ so strongly from the Arctic forms that they should be regarded as independent species, viz.,S.decipiens Ehrh. and S.bohemica Panzer. There is some doubt as to the identity of S.caespitosa L. with S.groenlandica L. Engler and Irmscher identify S.groenlandica partly with S.caespitosa subsp.decipiens Ehrh., and partly with subsp.eucaespitosa andf.uniflora. Litvinov, however, classes the herbarium part of the Siberian material as S.groenlandica. These definitions characteristically correspond to low-growing specimens. In this particular case, the size of the plant cannot be considered as a systematic character for the differentiation of 2 species, since all the more southerly forms are larger within the limits of the described species. It is very difficult to ascertain the true status of S.groenlandica L. owing to the variety of the material from Greenland. Cycle 3.

Litvinov reports for Sakhalin var.pseudoburseriana Schmidt with broader and more lustrous leaves; it deserves separation as an independent species, but lack of material renders this impossible. Note 2. S.bronchialis L. andS. spinulosa Adams are two very closely related forms. Abundant material from Siberia shows that there are many transitional forms, which apparently hybridize strongly. The permanent distinguishing characters are flower size and leaf shape. S.spinulosa Adams varies greatly; the Arctic and bald-mountain (Sayans) forms are smaller and more compact, with denser, somewhat curved but always flat leaves; the Ural and Russian-European are distinguished from the typical (Transbaikalian) forms by their larger flowers, but cannot be classed as S.bronchialis owing to leaf shape. 143 185 186 56.

Note. Collected by Wright, a member of the Reinhold and Rodgers expedition, probably on the west coast of Kamchatka; there is no precise data as to where the specimen was collected; this species has been included in the Flora of Kamchatka on the basis of that single specimen; the type is preserved inthe Paris Museum. V.L.Komarov is doubtful as to the occurrence of this specimen in Kamchatka, for nobody else has found it there. Hulten (Fl. Kamch. III (1929) 35) puts forward the hypothesis that this species was collected in Sakhalin, Hokkaido, or the Kurile Islands, and excludes it from the Flora of Kamchatka. On account of these indefinite views, it seems risky to include C.wrightii Franch. et Sav.in the Flora of the USSR. 6. C. flagelliferum F. Schmidt, Reise in Amurl. und Sachal. (1868) 134; Tr. Sib.

Very variable species; the following characters vary throughout the distribution area: overall size of plant, size of leaves, shape of petals, number of radical leaves, shape of cauline leaf and its position on stem, number of staminode lobes. Different combinations of these characters can be observed in various geographical regions, enabling the division of the species into races.

The latter, apart fromdenser leaves,is usually differentiated by more compact inflorescences, with number of flowers often reaching 7, and by the lower growth and branching shape of the shrub. Morpholigically, however, these two forms cannot be separated, for there are imperceptible transitions between them. The open-habitat form has been cited for the USSR as P.manshuricus Nakai. A plant from the vicinity of the city of Seoul, Korea, differentiated by the dense, drooping pubescence of the pedicels, has been described under this name. Specimens similar to the latter are available from many Korean and Manchurian sites, but do not occur in the Soviet Union; there is therefore no reason to retain P.manshuricus Nakai onthe list of Far Eastern plants. Economic importance. Ornamental and nectariferous plant, often cultivated in gardens and parks of the European part of the Soviet Union. 3. P.schrenkii Rupr. et Maxim. in Bull. Ac. Sc. St. Pétersb.

Cultivated in gardens and parks of the European part of the Soviet Union. Note. The specific independence of P.schrenkii is very doubtful: it is very closely related to P.tenuifolius and, in practice, cannot always be differentiated from specimens of the latter growing on open slopes; the only distinctive character of P.schrenkii — pubescence of the style — varies greatly, and some specimens have very few hairs at base of style; this may sometimes be observed also in the forest form of P.tenuifolius. *P. latifolius Schrad. ex DC.

R.pallidiflorum shows great polymorphism ina series of characters: (1) the pubescence, varying greatly in density and character between different specimens — this, incidentally, is more or less peculiar to other species of the subgenus Ribesia; (2) size of leaves and shape oftheir lobes; (3) flower color, which is always pale but varies from pale yellow to pink. Attempts to ascertain the geographical character of these variations have failed, but it should be noted that in Kamchatka and N. Sakhalin, as compared with the mainland, the prevalence of specimens with very large, usually broad-lobed leaves is characteristic, and that specimens with leaves almost devoid of pubescence (not yet known on the mainland) are of frequent occurrence, 10.

(1907) 347 (ex parte).— R.cyathiforme A. Pojark. in Bull. Appl. Bot., Genet. and Plant Breed. XXII, 3 (1929) 344, f.51), is distinguished by its narrower flowers, the hypanthium 1.5 times or more longer than broad, narrower sepals,and usually split style. This variety occurs only in a certain part of the distribution area of R.nigrum L.,namely in the mountain regions of Kazakhstan where it is widely distributed together with the typical form (var.europaeum Jancz.,l.c.). In southern Siberia it occurs infrequently, and it is difficult to separate the two forms, which are linked by transitions. Note 2. No reliable information regarding the occurrence of R.nigrum in the Caucasus has been available until recently, although in 1924 E. Wolf (in Mitteil. d. deutsch. dendr. Ges. XXXIV (1 924) p. 330) described the variety R.nigrum var.caucasicum E. Wolf after a specimen grown from seeds allegedly received from the Caucasus. For this specimen he reports 1—4-flowered racemes, with pedicels shorter than flowers, hemispherical- campanulate hypanthium, light green, sometimes slightly pigmented sepals, dentate or even lobate petals, often irregular in shape, and even several properties concerning the color and shape of buds and flower-buds. The black currants I found in 1936 in the Daralagez Range (Armenia), on the rocky banks of the Arpa-chai and Istisu rivers, were collected during fruiting and therefore could not be compared fully to var.caucasicum, but the following differences from the latter may be noted: more abundant 4—9-flowered raceme and entire, acute, ligulate, short-clawed petals of regular shape. Thus, the question of the Caucasian mountain currants versus the European currants is an issue to be settled when more complete material is available. Economic importance. R.nigrum L.is the ancestor of nearly all varieties of cultivated black currants. It is very valuable for the abundant vitamin C in its berries. The berries are eaten raw and are used for making jam, syrup, jelly, canned food, candy, marinades, refreshing drinks, fruit wine, infusions, and liqueur. The leaves are used for vegetable preservation and sometimes as a tea substitute. Percentage chemical composition of berry sap according to Hegi: 36.1 — water, 10.4—12.8 sugars, 2.7—3.7 free acids, (mainly malic acid), small quantity of pectins, 0.7—0.93 — ash; ash content: 16.4% CaO,13.8% P,O,,5.2% MgO. The leaves, and especially the flowers and buds, contain essential oil. Ornamental shrubs. Variegated- and laciniate-leaved forms are known (f.apiifolium and f.aconitifolium Kirchn). 254 Series 2.

In his monograph, Janczewski, who understood the species R.orientale Desf.sensu latb., and who groups under this name all species of the series Orientales, separates the Caucasian plants as a distinct variety, R.orientale var.genuinum Jancz., indicating that they are distinguished from the Lebanese plants (R.orientale var. resinosum Jancz.) by their dark green, lustrous, flat leaves, with mat, grayish, slightly rugose leaves. 198 259 Due to the lack of herbarium specimens from Asia Minor, Lebanon, and Greece, it is impossible to verify and evaluate the taxonomic significance of the differences indicated nor has it been possible to ascertain whether in the E. Mediterranean area one is dealing with one species, or whether here — as in Middle Asia — the currants of the series Orientales are differentiated into several geographic races. 27.

Type in London. Note. Linnaeus described 3 species of European currants considered by recent authors as varieties of a single species: R.reclinatum L. (R.grossularia v.reclinatum Berl.,R.g.y glabrum W. Koch), R.grossularia L.(R.g.@ glanduloso-setosum W. Koch) and R.uva crispa L. (G rossularia uva crispa Mill.,R.g.B pubescens W.Koch., R.g.veuva crispa Jancz.). G.uva crispa (L.) Mill. There are grounds for considering this an independent species native only to S.and W. Europe. It is distinguished by ovaries covered with a dense pubescence of simple hairs, small, yellowish, pubescent berries, smaller, densely pubescent leaves, absence ofacicular spines at internodes of shoots, smaller size, and later (by 2 weeks) flowering. In the Soviet Union, G.uva crispa occurs only in cultivation 270 in a number of varieties yielding small, very sweet, pubescent berries, or as anescape. As regards the 2 other Linnaean species, lack of material has prevented elucidation of their interrelation; it may be correct to group them, as Spach did, in one species. The fact is that the distinguishing character — the glabrous or glandular -hispid ovary — is not constant, showing a series of transitions. The distribution of these forms within the limits of the range is not uniform: the glandular-hispid form is frequent in Europe, whereas specimens with glabrous ovary occur rarely; in the Caucasus, however, there are almost exclusively specimens with glabrous ovary. Clarification is also needed as to whether the Caucasian currant is identical with the European in other characters. Economic importance. This is the ancestor of most cultivated varieties of currants. The berries are eaten raw or are used for making jam, syrups, jelly, and fruit wine. Chemical composition of the berries, according to Wehmer (percent): water 85.4%, invert sugars 4.67, saccharose 0.41, free acids 1.9 (malic), tannic acid 0.089, nitrates 0.94, raw cellulose 2.7, ash 0.51; the ash is rich in alkali (ca.49%) and phosphoric acid (19.68%); the seeds contain ca.19.8% of fatty oils; according to Hegi, the berries contain (percent): 84—88% water, 6—8 dextrose and levulose (not containing saccharose), 0.3—0.57 nitrogen, 1.13 pectins, 3.52% cellulose, 1.42% free acids (citric, tartaric, and malic; unripe berries also contain succinic acid), ash, and a small quantity of tannic acid and resin. 2.

Occurs in gardens of the south coast of the Crimea. Native to E.and SE states of the U.S. A.and Texas. Cultivated in gardens and along avenues of southern and central Europe and of N. America as a valuable tree species with ornamental and technical applications. A hybrid between P.orientalis L. and P.occidentalis L., described as P.acerifolia W.,is to be found in the gardens and along the avenues of W. Europe, where it is known as "London" plane tree (em. Henry a. Flood., The History of the London Plane. Proceed. R. Irish. Academy Vol.XXXV,sect. B, No.2. Dublin, 1919). Family LXXVII. ROSACEAE JUSS. Flowers cyclic, actinomorphic in USSR species, bisexual, less often diclinous, solitary or in inflorescences of various types. Perianth mostly biseriate, in rare cases petals absent (Alchimilla.). Sepals and petals usually 5, less often 3,4,6,8,or many; sepals, petals and stamens often arranged on edge of flat, patelliform, cuplike, or goblet-shaped inflorescence axis —the receptacle or hypanthium (sometimes incorrectly called calyx tube); sepals herbaceous, mostly persistent, sometimes outer sepals present. Stamens mostly 2—4 times as many as sepals, or else of indeterminate number, occasionally only 1—5; filaments free. Carpels as many as or 2—3 times as many as sepals or of indeterminate number, free or united with inner wall of hollow flower axis, unilocular, mostly with 2 pendulous or erect anatropous ovules, mostly separated from stamens by broad glandular disk. Style at apex or on ventral side, very rarely on the back. Fruits very varied: follicle, achene, stone-fruit, sometimes — owing to aggregation with expanding flower axis — forming pseudocarp or aggregate fruit. Seeds mostly small, usually with little developed endosperm. — Trees, shrubs, perennial herbs, rarely biennial or annual, with a spiral, very rarely opposite leaf arrangement, with stipules often adnate to petioles, less often exstipulate.

Grossheim cites S.obovata W.et K.for the Caucasus. This species, distinguished from S.hypericifolia by larger flowers, longer pedicels, and absence of stomas on upper surface of leaves, grows wild only in France and Spain; inthe Caucasus itisreplacedby S.hypericifolia L., which varies more in the Caucasus and the mountain regions of Central 234 i805 306 Asia than it does in the European part, and which often produces larger flowered specimens than the typical plants, which were apparently taken for S.obovata W.et K. S.hypericifolia X S.crenata. — Hybrids between these species occur rather frequently in the Caucasus (Dag., E. and S. Transc.) and rarely (ii: Don, V. -Don) im the “European part.’ In their morphological characters they approach one or other of these species. They can easily be recognized by the structure of their inflorescences, which are often sessile umbels on one branch in the upper part, lower down corymbs on a more or less developed leafy shoot, as in S.crenata but with longer pedicels; leaves on sterile shoots resemble those of S.hypericifolia but with lateral veins approximate at base and more or less parallel to the midrib as in S.crenata, with dentation also similar to that of S.crenata. 22.

NoteruS ustelli pila: C.K) Sehniis recorded foriihe wvieinitviot Vladivostok. Schneider indicates this species for Japan, as opposed to the continental S.sorbifolia (L.) A. Br., having densely pubescent ovaries, pedicels, and lower part of hypanthium. Schneider distinguishes between S.stellipila var.typica — with leaves densely pubescent below with bushy hairs — and var.inserta with glabrous leaves. Examination of abundant herbarium material has failed to confirm the presence of differences between the Japanese and the continental plants as indicated by Schneider: both plants are characterized by the densely pubescent ovaries, pubescent pedicels, and often also pubescent hypanthium; specimens with only slightly pubescent ovaries occur very rarely. Pubescence of bushy hairs can also not be considered as a specific character, Since Specimens with such pubescence are distributed — though irregularly — throughout the distribution area of S.sorbifolia: in the western part of the area they are rare, whereas in the eastern part (in S. Yakutia and the Far East) they are quite common.

Fl. June, fr.September. Mountain regions of the USSR; mainly on stony slopes, open or overgrown with shrubs and forests, in the middle mountain zone, rising locally to the subalpine zone; in the plains of the distribution area — in open forests and groves, also mainly on stony soils. — European part: Kar.-Lap., Dv.-Pech., Lad.-Ilm., U.

(Kuldja), N.Mong., Jap.-Ch. (Manchuria, rarely). Described from Dnepropetrovsk (formerly Ekaterinoslav). Type unknown. Economic importance. Ornamental shrub widespread in gardens and parks of the Soviet Union; various hybrids of C.melanocarpa with other Cotoneaster species may also be of interest for cultivation. Note. C.melanocarpa varies greatly in size, shape of leaves and their pubescence (especially above), size and pubescence of axial parts, size of fruits and density of their glaucous bloom. However, the examination of abundant herbarium material did not permit determination of the relationship between these characters and the distribution area. This species is sometimes cited for the Soviet Union under the erroneous name C.nigra Wahlenberg (or Wahlberg); these 2 combinations should, however, be excluded even from the synonyms of C.melanocarpa, for they were reported by the above-mentioned author due to a misunderstanding. C.melanocarpa naturally hybridizes with a series of other Cotoneaster species, and some of these hybrids are quite common. C.melanocarpax C.multiflora Bge.— Hybrids often-ocerramne in the Caucasus and very often in Central Asia (Dzungarian Ala-Tau, E. and Centr. Tien Shan). These hybrids are very frequent and varied as to the character of combinations of parent species, either occupying an intermediate position between them or closer to one than the other. A number of them are described under binomial specific names. The following belong here: — C.ignava E. Wolf (Izv. Lesn. Inst. XV (1907) 240) (Central Asia), which is fully intermediate between the parent species, having dichasially branching inflorescences with pink corolla more open than in C.melano- carpa, with brown-red, nearly black fruit, and the leaves pubescent below.— C.pseudomultiflora M. Pop. (Byull. Mosk. Obshch. Est., nov. ser. XLIV (1935) 127) from the vicinity of Alma-Ata, with densely pubescent lower surface of leaves, many-flowered compound corymbiform inflorescence, white open corolla, and globose dingy purple-red fruit. — Crs bam tit vomstar Wi Pop: (1. c. 126) (vicinity of Alma-Ata) is more closely related toC.multiflora than the preceding: leaves slightly pubescent below, fruits globose and bright red. The following apparently also belong to the group of hybrids of C.melanocarpa X multiflora: — C.megalocarpa M. Pop. (1.c.128) (Alma-Ata), with large leaves pubescent below, abundant fruiting, and large vinaceous-red fruits 10-11 cm in diameter; — C.polyanthema E. Wolf (Mitteil. d. deutsch. dendr. Gesellsch. 1924, p. 325), from the Alma-Ata vicinity, very closely related to C.melanocarpa, from which it is distinguished by its many- (11—25-flowered) inflorescence, its white, divaricate petals, smaller leaves of flowering branches, very irregular ripening of fruits, which are lustrous black with slight glaucous bloom, and a vegetative period one month longer than that of C.melanocarpa. The indications of earlier authors also pertain to these hybrids: C.laxiflora (non Jacq.) Bong. et Meyer in Suppl. II, Fl. alt. (1841) 190, and also C. vulgaris 6 erythro- carpa Ldb. Fl.

Scandinavia, and S. Finland). Described from Europe. Economic importance. Not widely cultivated in the Soviet Union; most indications (usually as C.vulgaris) should be referred to C.melano - carpa. Note. Occurs in the Soviet Union only in the Crimea and the Caucasus; all reports concerning the European part, Siberia, and Central Asia are erroneous and refer partly to C.uniflora Bge., partly to C.racemiflora (Desf.) C. Koch, but mostly to C.melanocarpa Lodd. which, when its fruits are immature, is often not differentiated from C.integerrima or else is reported as one of its forms (C.vulgaris v.haematocarpa Rupr.), whichis none other than C.melanocar pa Lodd. These two species, however, may be clearly differentiated in the various phases of growth: C.melanocarpa has a different inflorescence structure, with well developed axis and long pedicels, more open flowers, larger and brighter petals; the brown-red color which characterizes the immature fruits of C.melanocarpa has not been observed inC.integerrima fruits at any Stage of maturity, and the tomentose pubescence on the lower surface of leaves is looser and consists of longer hairs. C.integerrima Medik.X C.melanocarpa Lodd. — Hybrids occasionally occur in the Caucasus (Cisc., Dag., Armenia). In shape and leaf pubescence these hybrids approach either C.integerrima or C.melanocarpa; inflorescences with well developed axis as in C.melanocarpa, but few- (3—5)-flowered, with more or less developed tomentose pubescence; fruits dark red or black, without glaucous bloom, small, nodding, with usually 3, less often 2 or 4 nutlets; style arising above the middle. C.integerrima Medik.X C.racemiflora C.Koch.— Hybrids are apparently rare (vicinity of Shemakha and Sardar-Bulak); leaves small, close to one or the other species in shape and pubescence of leaves; fruiting poor; fruits in twos or threes, axillary or in corymbs, with tomentose pedicels, erect or nodding (even on the same branch), red, with 2 nutlets, narrower than in C.racemiflora,the style arising in upper part. i 4, C.uniflora Bge.in Ldb., Fl.

Gen.distr.: Chinese Dzungaria, Mong. — Tuva ASSR, NW Mongolia. Described from the Altai. Type in Leningrad. Note. It is difficult to ascertain on the sole basis of herbarium material — specimens from a few districts being quite insufficient — whether there is only one species or whether several very closely related geographic races should be separated. It should be noted that the monocarpous Cotoneaster from the Kola Peninsula and the Urals has, on the average, broader and larger leaves and larger fruit than the Altai specimens; it is unclear whether there are differences in color of petals; as a rule these are purple-red in Siberian plants, whereas orange-red petals predominate in northern plants (only the latter are known in the Khibiny mountain region) and yellow -fruited specimens (var.lutea Fries) occur. In the Pamir-Alai, in addition to subglabrous specimens indistinguishable from those from Altai, there are specimens with dense, almost tomentose pubescence below, which has been observed neither in the Altai nor in the Kola Peninsula.

They usually differ from C.melanocarpa in more impoverished, often 1—3-flowered raceme, but with more developed axis and pedicels than in C.uniflora. The pubescence on the underside of the leaves varies from slight to tomentose, and the leaf shape is closer to one or other of the species.

Rarely cultivated in the Soviet Union, but deserving attention, being more ornamental than C.melanocarpa which is cultivated in the Soviet Union; fruits more brightly colored, inflorescences larger, with white, open flowers. Note. C.multiflora forms hybrids with a number of other species of this genus: C.multiflora Bge.X C.insignis A. Pojark. (p. 255); C.multiflora Bge.x C.melanocarpa ’Lodd: (p. 247); C.multiflora Bge.X C.racemiflora C.Koch. The latter have been found in the Caucasus and occur quite frequently in Central Asia (Dzungarian Ala-Tau, Centr. and E. Tien Shan, and Kopet Dagh). They show very varied combinations of the parental species characters, being either intermediate or else closer to one or the other. In hybrids closer to C.multiflora the petioles are rather long; leaves rather sparsely appressed -pubescent below, mostly obtuse, obovate; inflorescence loose, profusely branching, many -flowered, the pedicels more or less slender and long, usually pubescent, sometimes tomentose; fruits mostly glabrous even when young, often oblong. In hybrids closer to C.racemiflora the leaves are mostly ovate or elliptic, larger than those of C.racemiflora (3—3.5cm long, 1.5—1.8—2 cm broad), with either short or longer petioles, the blade rather sparsely pubescent to tomentose below; inflorescences more compact, with short thick axes and pedicels, more impoverished, corymbiform, usually tomentose-pubescent; fruits hairy when yuung.

Cisc., Dag., E. and S. Transc., Tal. Centr. Asia: Mtn. Turkm. (Kopet Dagh, Aidere Gorge). The presence of wild quince in Pam.-Al. has not been ascertained; it has been reported for the Bald'zhuan district, at the Pulisang Bridge on the Vakhsh River, and for the Zigdi Pass; possibly growing wild in W. Tien Shan, near Kara-Ungur (Kattar -Yangak natural boundary area). Escaped in Crim. Gen.distr.: Arm.-Kurd. (As. Min.) and N. Iran. Widespread in cultivation and naturalized almost throughout the Mediterranean area, escaped in many areas of Central Europe. Cultivated as far north as Scotland and Norway (63° 51' N.). Described from the Danube. Type in London. Economic importance. Cultivated for its fruits, which sometimes weigh up to 2kg. Wild quinces bear few-fruits (2-10 each) and are not an important source of raw material in the national economy. The fruits are hardly ever eaten raw but are cooked or baked, used as condiment and for the making of jam, jelly, marmalade, syrup and drinks. In medicine quince seeds serve as purgatives and laxatives; their mucilage is mainly used externally to cover and refresh. The extract prepared from the mucilage and iron and an infusion of the latter are used instead of ferric malate infusion and extract. The mucilage is used in the textile industry for giving a gloss to materials; its aqueous decoction can replace gum arabic. Seeds contain 20—22% mucilage and 15% of fatty oils, amygdalin, the enzyme emulsin, tannins (in seed coat), proteins, dyes, and 13% ash. The colloidal aqueous solution of mucilage (50:1) yields under the action of diluted acids 34% of a substance reacting like cellulose. The fat contains 336 myrsinic acid. The pulp of the fruit contains 9.6% sugars, mostly levulose, malic and tartaric acids, and a small quantity of tannins. Quince is also cultivated as an ornamental plant; there is a form with variegated leaves (f. marmorata (Dipp.) C.K. Schn.) and a pyramidal form (f.pyramidalis (Dipp.) C.K. Schn.); tolerant of clipping, used for hedgerows; serves as a Stock for grafting delicate dwarf varieties of pear and apple trees, Eriobotrya japonica and Photinia. Requires deep, loose, fertile, moist soil; iscultivated from seeds, coppice shootsand root suckers. Provides honey and pollen for bees. The whitish wood, regular in structure and medium-hard, is easily cut and used for various small articles. Nearly all old trees are affected by heartrot caused by the fungus Fomes fulva; another fungus, Sclerotinia cydoniae, affects the leaves, decreasing the size of the fruits and the general yield.

Gen.distr.: all of Europe (except Great Britain and Denmark and the Iberian Peninsula where it is found only as an escape), N. Anatolia, N. Iran. Described from Europe. Type in London. Note. Very variable in all its characters — size and shape of crown, presence of spines, shape of leaves, degree of pubescence, etc. , especially size, shape, and taste of fruit. There are two basic types, differing mainly in shape of fruit, with numerous varieties and forms: Achras with pyriform and Pyraster with globose fruit; these two basic types are sometimes described as separate species, but there is no basis for this differentiation. Moreover, the cultivated forms derived from P.communis without hybridization are often united as var.sSativa DC., distinguished by absence of spines and by larger fruits. Economic importance. The common pear is the ancestor of up to 1,500 cultivated forms. The most ancient of these, which have changed little, are derived directly from this species; most varieties, however, are the result of hybridization with other species. Pear trees were first cultivated in ancient Greece, then penetrated into Italy, and later became widespread in Europe. Wild pear fruits are usually tart, becoming sweeter if stored. They are used in various ways depending on their gustatory qualities: they are eaten raw or dried, stewed, or used for making of drinks (kvass, cider) or as fodder for cattle. The utilization of wild pear fruits is of great importance in Ciscaucasia, where in the Krasnodar Territory alone, according to Trusevich, pear forests with an admixture of apple 339 261 trees occupy 30,347 hectares, and the possible yield (together with the apples) is estimated at 139 thousand tons. Wild pear fruits contain 70—85% water, 6—-13% sugar, 0.1—0.2% acids (mainly citric and malic), 0.29% ash, tannins, etc. The seeds contain 12—21% fatty oils. The wood is heavy, specific gravity 0.72, fine-grained, solid, reddish brown, an excellent imitation of ebony when covered with blackvarnish; used for lathework, cabinet-making, and musical instruments. A light brown dye is obtained from the bark. 2. P.balansae Decaisne, Le jardin fruitier de Museum I (1871—1872) 319; Voronov in Bulletin of Appl. Bot.

May. (Plate XX, Figure 2) Forests and river valleys in the lower mountain zone.— Far East: Uss. Gen.distr.: Jap.-Ch. (Manchuria, Korea). Described from the Ussuri River. Type in Leningrad. Note. This species varies in size, shape, color, and taste of fruit, on the basis of which Skvortzov has described several varieties which may be of importance for selection. Economic importance. The fruits may be eaten raw or dried; to improve their taste they are fermented in heaps and then salted. They are sold in Manchurian markets as ''li.'' Being very frost-resistant, this species is valuable as stock for grafting for northern horticulture and attention is being given to this possible use. The dense, heavy wood has the same applications as that of P.commun is. P.ussuriensis was introduced into cultivation in Europe by the Petersburg Botanical Garden from seeds collected in the Far East by Maack. 6. P.asiae-mediae M. Popov in Bull. of Appl. Bot.

May. Apple-and-walnut forests, in river valleys on deep alluvial soil. — Cenine. Asia: T.Sh. (Pskem River valley). Endemic. Described from Mullyal. Type in Leningrad. Note. This species has not been fully studied, nor has its distribution area been precisely determined; it is closely related to the Chinese P.lindleyi Rehder (=P.sinensis Lindl.) and to P.ovoidea Rehder. The calyx, persistent in fruit, clearly distinguishes it from P.serotina Rehder, widely cultivated in E. Asia.. It has not been determined whether the Central Asian P.asiae-mediae is wild -growing or an escape. The latter is more probable, especially since the varieties cultivated and rather widely distributed in Tadzhikistan and Uzbekistan are derived from P.sinensis Lindl. and from its hybrids with F.communis L. These varieties are known in Tadzhikistan as 'Noshputy" and ''Nok" (see Viktorovskii in ''Trudy Tadzhikistanskoi kompleksnoi ekspeditsii"' [Transactions of the Tadzhikistan Combined Expedition], No. XIII, 1935). Economic importance. Like the other forms, P.sinensis s.l.is valuable for cultivation and selection on account of its very sweet fruits, much appreciated by the population of Central Asia. In addition, varieties of P.sinensis s.1. and its hybrids with P. communis are noted for their high yields, are highly resistant to fungal diseases, and suffer little from Laspeyrisia pyrivora. For these reasons they are particularly valuable for cultivation in the southern USSR. 265 346 7. P.grossheimii A. Fed.in Tr. Arm. fil. Akad. Nauk II (1937) 203. Tall or medium-sized tree with conical crown and blackish verrucose branches; petioles long (to 10cm); leaves 8—10cm long, 4—5cm broad, ovate-elliptic, broadly rounded at base, tapering-acuminate, slightly plicate along the midrib, acutely serrulate, lustrous green; flowers unknown; fruits with slender pedicels to 5cm long, globose-pyriform, 2—2.5cm long and as broad; sepals spreading, tomentose-pubescent. Hornbeam-oak forests (Quercus castaneifolia) of the middle forest zone.— Caucasus; Tal. Endemic. Described from near the village of Lerik. Type in Erevan. Note. According to A. A. Fedorov, this species is distributed ''in the virgin forests of Talysh." It is interesting to note that pear varieties of the series Sinenses are cultivated in Talysh and in Mazanderan; however, it still should be determined whether P.grossheimii in Talysh is not in fact an escaped form. Series 4. Ponticae Maleev.— Proles Pontica Decaisne,l.c.,123.— Leaves narrowly or broadly lanceolate, less often to narrowly oval or narrowly elliptic, entire or obscurely denticulate, densely villous or sericeous-pubescent like other parts of plant, the pubescence persisting at least on underside of leaves, less often the pubescence disappearing toward fall.

Gen. distr.: Bal.-As. Min. (Anatolia), Arm.-Kurd. (Turkish Armenia). Described from the Crimea. Type in London. Note. Varies greatly in leaf size and shape and in degree of leaf pubescence; this is observed on different trees as well as on different shoots of the same tree; size and Shape of fruit also very variable. Economic importance. Distinguished by its strong drought resistance; grows well on dry and stony soils; also very resistant to frost (down to minus 20—30°). These properties make it a most valuable species for forestry and horticulture, since it can be cultivated in the steppe zone. Its importance for dry district horticulture is mainly as a drought-resistant stock suited to poor soils, and as such it is widely cultivated in E. Crimea (see Voinov, l.c.). This species should also be used for hybridization. In addition, it has ornamental value and may be used to provide greenery in the same regions. In the Crimea the fruits of Ppelaeagrifolia have the same uses as those ofthe common wild pear, since both have the same properties. P.elaeagrifolia Pall.X P.communis L.— Distinguished from P.elaeagrifolia by less dense, more fugacious pubescence of leaves and other parts of plants, by subglabrous or quite glabrous branches, and by broader leaves resembling those of P.communis, usually conspicuously dentate, especially in upper part of blade. — European part: Crim.

Described from Ciscaucasia from the region between the Kura and Terek rivers, in the 'Dubki" Hills near the Chervlenaya railroad station. Type in Leningrad. Note. Very variable in shape of leaves and shape of fruits, which are either subglobose or ovoid-pyriform. The variability in leaf shape can be observed even on different shoots of the same tree, which makes it impossible to separate any constant forms, at least without detailed observation in situ or without special collections. An extremely narrow- leaved form from the vicinity of Borzhomi and Tbilisi has been described as P.argyrophylla Diapulis. Examination of the considerable material from these regions has not enabled identification of this species, for it falls entirely within the variation range of P.salicifolia, the narrow- leaved form of these regions being linked by a full range of transitions to broader -leaved specimens of P.salicifolia growing in the same regions; in addition, the narrow-leaved form also occurs in other parts of the P.salicifolia distribution area. Broader-leaved specimens of P.salicifolia are often confused with P.elaeag rifolia, from which they are clearly distinguished by leaf shape and, in particular, by the type of pubescence.

The taxonomy of representatives of this series has been studied very little; there are basic differences of opinion between the various authors as to the determination of the number of species and their names. All these forms are mostly attributed to one polymorphic species called Pyrus malus L. or Malus communis Lam.; at best this is subdivided into 2 or 3 smaller’ species (often the borderlines between them are unclear and the names chosen arbitrarily), for example: M.silvestris Mill. and M.pumila Mill.,or else M.silvestris Mill.,M.dasyphylla Borkh., and M.pumila Mill. (see especially the last summing-up article by the well-known Soviet pomologist V. V. Pashkevich, ''Yablonya'' [The Apple Tree] in the periodical ''Priroda'' [Nature] 1938, No.5). The study of this group presents tremendous difficulties (at present insuperable), mainly due to: (1) the impossibility of differentiating strictly between wild and escaped forms and, a fortiori, between their hybrids; (2) the very considerable polymorphism of even undoubtedly wild varieties, which makes it difficult to apply the geographical-morphological method to this group and to its young, stillinsufficiently stabilized species; (3) the inexactitude and incompleteness of herbarium and museum material and of properly performed field observations. In accordance with the guidelines adopted in this work, we shall still attempt — partly relying on the recently published work of G. Koidzumi, ''A Synopsis of the genus Malus, " Acta phytot. et geobot. III, No. 4 (1934) — a slightly different approach to the material at our disposal, while specifying that this treatment does not pretend to be definitive, attempting only to raise a series of questions for future researchers of this group. Economic importance. The fruits of the species belonging to this group are edible, but those of the wild-growing varieties are seldom eaten raw owing to their high acidity; they are usually dried (for stewed fruit, etc.) or for the preparation of drinks. Nectariferous. The wood of some forms finds applications in carpentry and turnery, but is less valuable than pear- wood, because it warps and splits.

Don, Crim. ? Described from the banks of the Don and the Volga. Endemic. Type unkown (possibly in London); cotype (?) in Leningrad. Note. The present treatment has given this species a wider scope than did Pallas — who considered it primarily as a spiny shrub form from the Don and Volga banks — but less wide than that given to it by C. K. Schneider (Illustr. Handbuch der Laubholzkunde, Bd. 1(1906) 715); the latter author included in this species wild Near Asian and Central Asian forms. We have followed D. I. Litvinov (in herb.) in referring to M. praecox the tall, wild apple trees from the more southerly regions of the European part of the USSR, with leaves pubescent below. These forms are sometimes identified with M.dasyphylla Borkh., Hand. Forstb. II (1803) 1271, but according to C. K.Schneider (1. c., p. 715) the latter is an escaped form of the cultivated apple tree, i.e., M.domestica Borkh.; it should be added that all the W. European material studied and classified as M.dasyphylla Borkh., (with one exception) apparently really pertains to the cultivated apple tree. The usual identification — originally made by Pallas himself — of M.praecox with such cultivated forms as M.pumila Mill.’s. str. or M.frutescens Medik. is apparently without foundation. 3.

M.orientalis is described here only provisionally, since it is to be described at a later date by Uglitskikh and requires a thorough study of the relation of its variation limits. Apparently, it is not the only wild Caucasian apple tree. For instance, the interesting Caucasian dwarf apple trees originally mainly from Dagestan are not described here due to the extreme scarcity of material. 4. M.sieversii (Ldb.) M. Roem., Syn. Rosifl.

Type in Leningrad. 279 364 365 Note. Among the apple trees considered as wild, M.sieversii undoubtedly is the one with characters closest to those of cultivated forms; it is interesting to note that even early authors had doubts concerning its "wildness" (Zalesov, for example, judging by the label on one specimen in the BIN Herbarium). Contemporary Central Asian botanists and travelers, however, insist that M.sieversii is originally from Central Asia. M. G. Popov, however admits the possibility of a widespread hybridization between the wild Central Asian apple trees and forms of M.dome stica Borkh. (oral communication). ; Economic importance. Owing to its comparatively large fruit and gustatory qualities, the Central Asian wild apple tree is of particular economic interest; in many districts the local population harvests a large yield of apples. 9.

In addition, transitional forms (or hybrids — M. Popov, 1. c.) may be found between them. Economic importance. Cultivated as ornamental and, in its native habitat, as a fruit-bearing tree. I. V. Michurin used this form, and especially its hybrids, for selection breeding of apple varieties with red-fleshed fruit. 6. M.turkmenorum Juz. et M. Pop. sp. nova in Addenda VIIL, p. 379.

Mountain slopes and gorges. — Centr. Asia: Mtn. Turkm. (Kopet Dagh). Endemic? Described from Mt. Syunt-Dag and the Gyuen Gorge. Type in Leningrad. Economic importance. The fruits are small and tasteless, hence the tree is not valuable for fruit-bearing. However, M.turkmenorum is of importance as stock for cultivated apple tree varieties, in view of its dwarf size, drought resistance, and salt tolerance; it has, however, the disadvantage of forming coppice shoots. 7. *M.domestica Borkh., Handb.

Small or often rather large tree with spreading crown, divaricate branches, and robust annotinous shoots; leaves mostly large, of variable shape, mostly ovate with rounded base, crenate-serrate, with persistent pubescence on both sides (much less strong above), short-petioled; flowers large, white or pink, usually darker on the outside, with rather short or short white-tomentose pedicels; hypanthium and calyx densely tomentose; fruits usually large, more than 3 cm in diameter, short-stalked. April — May. Many varieties cultivated in gardens, often escaping. Gen. distr.: now distributed throughout the world. Described after acultivated specimen. Note. A large number of cultivated forms derived from various wild apple tree species and races have been artificially grouped under the name M.domestica; it is therefore unavoidable that the morphological characteristic of this complex should be rather indistinct. It would have been more correct to distinguish within the limits of the composite concept M.domestica a Series of quite definite types differing in their origin — however, a rational classification of cultivated apple trees is entirely a thing of the future. Some varieties or groups of varieties have already acquired in the literature various binomial designations; such are, for instance, M.pumila Mill. Gard., Dictweds VIIIM 1768) Ss.

M.dolichomorpha Juz. ined., cultivated in the USSR mainly in the Crimea and the Caucasus, should also be mentioned, as should the "kandil-sinap" group of varieties characterized, among other things, by their pyramidal crown and elongated fruits. Economic importance. The fruits are used raw, dried, cooked. canned, for the making of jam, marmalade, pastilles, cider, etc. The sap contains sugars (glucose, fructose, saccharose), malic acid, tannins and albumins, 281 369 the respective quantities varying from one variety to another. The apples also contain a certain amount of vitamins A, B, and C. Series 2.

A hybrid origin (M.pumila Mill X M.baccata (L.)

Varies mainly in size and color of fruit. — Apart from the true M.prunifolia, the closely related M.cerasifolia Spach, Hist. Veg. Il (1834) 152, is also sometimes cultivated in gardens. It differs from the former mainly in its partly or completely caducous fruiting calyx, and is usually taken for a hybrid of | M.prunifolia K M.baccata. | Economic importance. Cultivated as ornamental; the fruits are known in the Soviet Union as ''Chinese apples" or ''paradise apple'’ and are used for jam. This species and its hybrids have acquired a considerable importance for selection breeding especially that of frost-resistant varieties. Especially significant results were achieved by M. I.

S.taurica,closely related to S.meridionalis (Guss.) Nym.— distributed in the W. Med. (Sicily, Sardinia, possibly Crete) — is distinguished from the latter by its leaves: less sharply cuneate-tapering toward base, with less acute teeth. The species S.flabellifolia Schauer, to which S.taurica and S.turcica are often referred,is described after a cultivated specimen of imprecisely known origin, and is distinguished from those species by its lobate leaves. S.taurica and S.turcica, differing only in unimportant characters and having overlapping distribution areas, are not clearly delimited; in the Crimea there are very many specimens transitional between these two species, whereas Caucasian and Asia Minor Specimens have clearly expressed S.taurica characters. Apparently this is a case of as yet uncompleted differentiation of one species into two— the Caucasian-Asia Minor S.turcica and the Crimean S.taurica. In the Crimea, S.taurica (possibly also S.turcica) often forms hybrids with S.graeca. 30. S.obtusidentata Zinserl. sp.n.in Addenda VIII, p. 384.

This species is apparently the result of a cross between S. armenica Hedl. (which it resembles in character of teeth) and S.aucuparia L. In any case, it is undoubtedly the result of crossing between species of the sections Aucuparia andAria. Note 2. In regions where species of the sections Aria and Aucu- paria grow together there occur hybrids characterized by their leaves, which are pinnatisect at the base, lobate higher up. Such hybrids have been found in W., E., and S. Transc. Some of these hybrids are cultivated. *S.fennica (Kalm. ) Fr., Summaveg. Scand.

X Crataegus monogyna Jacq., are unreliable, being based on leaves of sterile shoots which, unlike the typical Mespilus leaves, are slightly lobately incised. Economic importance. The fruits are edible, widely used by local population; the small wild forms as well as the large cultivated varieties are marketed. Owing to their tartness, the fresh fruits are used only after being affected by frost or when, after a period of storage, they become softer, more succulent and sweeter on fermentation. They make good marmalade and can be used for the making of drinks. The leaves, bark, and young fruits contain many tannins and are suitable for the tanning of leather. The fruit flesh contains 10.57 % invert sugars, 5.84% other nitrogen-free extracts, 7.51 % fibrous substances, 1.38 % malic acid; the seeds contain 2.5% fatty oils. Wood dense, very hard and heavy, yellowish white with reddish-brown heartwood, suitable for various turning jobs; produces coal of excellent quality, used as stock for grafting Japanese Mespilus. Ornamental. In the Soviet Union cultivated in the Crimea and in the Caucasus. There is no cultivated Mespilus in Central Asia. Among the cultivated varieties, the stoneless F.apyrena Duh. ae abortiva Dum. -Cours) should be noted. Genus 733. CRATAEGUS * L.** L., Sp. pl.(1753) 475. Flowers small, white, in mostly compound corymbiform, rarely simple umbellate inflorescences; ovary of 1—5 carpels free on ventral side or connate at base, adnate by the back to the hypanthium; ovules 2, the upper not developing; pome containing 1—5 nutlets (endocarp stony), with dry, persistent sepals at the apex, yellow, red, or black, rather fleshy. Small trees or shrubs with alternate stipulate pinnatilobate or partite dentate leaves. Economic importance. Ornamental trees and shrubs; many species are used for spiny hedgerows. The flowers are nectariferous and contain the yellow dye quercetin; their unpleasant odor is due to their trimethy- lamine content. The fruits of some species are large, fleshy, and tasty * From the Greek kratos, strength, sturdiness and agein, to lead, to act, referring to the sturdiness and hardness of the wood or to the presence of hard thorns providing a means of defense. ** Treatment by A.I.Poyarkova. 317 417 and are eaten, mostly raw, by the local population, mainly after frost; sometimes the fruit flesh is cut into small pieces and added to flour for the baking of sweet bread; sometimes the fruits are used for fruit jelly or .- stewed fruit or are even candied. The fruits are also eaten by birds, especially in Europe in winter, and are used as fodder for swine. The young leaves of certain species are used as a substitute for tea and are pleasant and refreshing to the taste. A decoction of leaves, bark, and roots is used for dying cloth light brown or yellow. The wood is fine-grained, dense, very hard and strong, heavy, reddish or yellowish, but difficult to split and treat; used for various lathework, tool handles, sticks, etc. Certain species are used in gardening as wildings for the grafting of apples, quince, and Japanese Mespilus. They reproduce by seeds which germinate with difficulty and are needed in stratification; very undemanding as far as soil is concerned. Since Crataegus isreadily attacked by various fruit tree pests, its presence near gardens is undesirable. 1s, \YStyles,3 -tordsy a nuts swith 3 a enitlets) i. eyes (adie ns Ke ee 2.

Gen.distr.: apparently Afghanistan. Described after a cultivated specimen reputedly from the Altai. Type unknown. Economic importance. Rather common in cultivation but usually confused with C.sanguinea Pall. Note. A hawthorn very closely related to C.altaica has been described from [former] British Baluchistan as C.wattiana Hemsl.et Lace (Journ. Linn. Soc. XXVIII, 1891, 323, tab. 40). Schneider considers it identical to C.altaica Lge. (Fedde, Repert. III, 1906, 229), Rehder; however, (Man. Cult. Trees a. Shr. 763) distinguishes two independent species, indicating a number of differences. Owing to the lack of material from Baluchistan, it is better to adopt the second opinion. 325 Hybrids of C.altaica Lge.X C.pontica C.Koch have been collected in W. Tien Shan. The specimens examined have white-tomentose-pubescent young shoots, axial parts of inflorescence, and petioles; leaves pubescent below or on both sides, usually resembling in shape those of C.altaica, less often those of C.pontica; fruits (immature) small, with 5 pitted nutlets, slightly flattened at the poles. C-dshungarica’ Abi. (p.351) is a hybrid of C.altaica Lge. X C.songorica C.Koch. Hybrids of C.altaica Lge.X C.sanguinea Pall.are rather common in regions where the two distribution areas coincide.

Maximowicz, quoting Krasheninnikov, cites in his list of Kamchatka plants a red-fruited as well as a black-fruited hawthorn. He believes that the latter may be C.sanguinea v.glabra Maxim.; this, in fact,is a synonym of C.dahurica Koehne, which does not grow in Kamchatka. It is likely that specimens of C.chlorosarca with immature fruits were mistaken for red-fruited hawthorn; a less likely possibility is that he had in mind Sorbus sambucifolia. 327 Economic importance. Ornamental, rarely cultivated in the Soviet Union; its substitute species,C.nigra C.et K. — distinguished by the dense velvety pubescence of underside of leaves and inflorescence, different leaf shape, and smoother nutlets — is more widely cultivated.

Extremely polymorphic species with wide, discontinuous distribution area. Geographical separation cannot be ascertained on the basis of herbarium material; this question can be solved only by studying the variability of C.pentagyna inthe field in the various regions where it grows. C.pentagyna W.et K. apparently readily forms hybrids with the most varied species; hybrids of C.pentagyna W.et K. XC.san- guinea Pall.=~C.lambertiana Lge.,@ipentagyna W.et K.oxX Cyerus galliL.=C.hiemalis Lge. Hybrids of C._pentagyna usually have dark fruits and can be recognized by the reddish color of the fruit flesh, by the deep umbilicus, and by the ascending fruiting sepals. The following hybrids of C.pentagyna are often found in the Soviet Union: C.pentagyna W.etK.XC.kyrtostyla Fingerh.— These hybrids are most often found in the Crimea, N. Caucasus, and W.and S. Transc. (Zangezur), E. Transc. (districts of Kirovabad and Kuba), and Talysh. The hybrids are mostly intermediate: fruits usually ellipsoid, from dark red to purple-black (without bloom), the flesh usually colored, with 2 or 3 nutlets (with slight admixture of fruits with 1 or 4 nutlets); inleafshape, pubescence, shape and position of sepals they show a range of transitions between the two species. These hybrids are usually cited as C.oxyacantha. C.pentagyna W.et K.XC.monogyna Jacq., collected in the Crimea and the N.Caucasus. These hybrids have dark red fruits, with mostly 2, rarely 1 or 3 nutlets; leaves bicolor, often with waxy bloom below, with few-toothed, mostly subobtuse lobes as in C.monogyna. Quite frequent in the Crimea; according to available material they show great consistency of characters and, therefore, should be described under a separate name — C.dipyrena A. Pojark.(p.351). Pallas's C.digyna Pall. (Ind. taur. 1796, p. 107 — nom. nud.) may belong here. C.zangezura A. Pojark. (p. 352) is one the hybrids whose parental species is C.pentagyna W.et K.

(Kura River valley and further south), Tal. Gen. distr:: Bal.-As. Min. and S. Greece. Described from the Crimea. Type in London. Economic importance. In the Caucasus the local population collects the fruits, which are distinguished by a pleasant, rather acid taste; they are found in markets and mostly eaten raw, less often they are ground and mixed with flour for the preparation of a sweetish bread. Owing to its drought-resistance, this shrub may be of as great interest for arid regions as C.pontica C. Koch, since individual specimens yield fruits as large and fleshy as those of the latter species. These very dense and spiny shrubs can be recommended for hedgerows. The wood is used for tool handles. Series Szovitsianae A. Pojark.— Fruits (apparently red) with 3 or 4 styles; fruiting sepals erect-spreading. One species. 11. C. szovitskii A.

Iran (districts bordering on Turkm.), Arm. -Kurd. (Turkey— a few sites in thi the Coruh River basin). Described from the vicinity of Ardanuch inthe Coruh River valley. Type in Berlin. Note. The Central Asian yeliow-fruited hawthorn with 2 or 3 nutlets is identical to C. pontica C. Koch from the Coruh River valley, therefore it should bear that name instead of C.azarolus as it has been erroneously reported until now. Comparison of C.pontica C.Koch with the South European yellow-fruited hawthorn known as C.azarolus L. has shown that the latter is distinguished both by shape of fruits (globose or slightly oblong, not flattened at the poles) and by very different leaf shape. Thus, there is no reason to consider C.pontica C.Koch simply as a synonym of C.azarolus; these are two well differentiated, closely related geographic races, as is the Near Asian yellow-fruited hawthorn — associated with them under the collective name C.azarolus — which has globose fruits, deeply parted leaves half as large, and spiny shoots, and which should be called C.aronia (Bosc) ex DC. It is not quite clear whether C. pontica in Transcaucasia is fully native or whether it is the result of naturalization of the Central Asian hawthorn introduced into cultivation and which, apparently, has been cultivated since antiquity far beyond the boundaries of its natural distribution area (e.g., in various areas of N. and Central Iran). Economic importance. Owing to the size, abundant flesh, and pleasant taste of its fruit and to its great drought-resistance, it may be of importance for the southern arid regions. The fruits are readily eaten by the local population and are marketed. Nectariferous, very ornamental; wood valuable for making small articles. Section 5.

Blo duneseine September. Shrub thickets on slopes.— European part: Crim. (near Karadag station in the vicinity of Feodosiya and near Alushta). Endemic. Described from | Karadag. Type in Leningrad. | Note. C.sphaenophylla has some characteristics in common with species of the series Erianthae, particularly with its Crimean representative C.taurica: villous pubescence of all parts, especially of inflorescence, similar shape of sepals, and fruits somewhat angular toward base. However, its other characters are completely uncharacteristic of that series: consistently 1 style (nutlet), rather light purple-red fruits with a waxy bloom.. If the possibility of C. sphaenophylla being a hybrid of) © =tamraca is admitted, it will be very difficult to imagine its second parent-species, since C. sphaenophylla is distinguished by a very peculiar leaf shape, different from that of other Crimean species, and by rather light-colored fruits; C. microphylla, the Crimean hawthorn with the lightest-colored fruits, should definitely be excluded as a possible parent species of C.sphaenophylla because of its simple, few-flowered inflorescences, erect sepals, add the characteristic shape and dentation of its leaves. Economic importance. Highly ornamental due to the distinctive shape of the leaves and the brightly colored fruits. 442 Series 4. Ambiguae A.

Described from Sarepta (Krasnoarmeisk). Type in Leningrad. Note. This hawthorn was known to Pallas, who distinguished it from the Russian red-fruited species of the section Oxyacantha, describing itas C.monogyna var.nigra, stressing its characteristic appearance and correctly plotting its distribution area (S. Russia, Volga, apparently Sarepta — from which the collections of Pallas came — and N. Caucasus). The drawing quoted by Pallas in Fl. Ross., though incomplete, permits recognition of that species and shows its difference from dark-fruited C.ambigua C.A.M. Later botanists have overlooked this, thus 346 455 Yu.N. Voronov did not distinguish it from C.ambigua C.A.M.,as can be seen from his identification of herbarium specimens from the SE of the European part, preserved in the BIN Herbarium. Series 7.

By comparison with C.kyrtostyla,C.monogyna has a much narrower distribution area in the USSR, confined to the European part and 347 456 457 to more southerly districts, especially in the east, and scarcely penetrating into Transcaucasia.

Gen. distr.: Arm. - Kurd.and Iran. Described from Armenia (vicinity of Erevan). Type in Leningrad. Note. This species is widespread in S. Transcaucasia (vicinity of Erevan, Daralagez, Megri District), where it is confined to shrub thickets developing on stony slopes in the middle forest zone; grows also in W. part of Azerbaijan, in Dagestan, and in Georgia. Researchers of Caucasian flora usually classify it, together with other species,as C.monogyna, although the first specimens of this species from the vicinity of Kirovabad were cited in the literature by Hohenacker as C.heterophylla Fligge. The latter name is used by Medvedev with a description made after Hohenacker's specimen and with a single reference to him; Grossheim, in Flora Kavkaza, cites it as doubtful, giving an insufficiently exact diagnosis. The herbarium specimens and the cultivated specimen from the Toulouse Botanical Garden after which C.heterophylla Flugge was described, differ greatly from the Transcaucasian specimens and are 348 definitely not to be identified with them. Spain is the native habitat of C.heimer‘ophy lita. 30. C.turcomanica A.Pojark.sp.nova in Addenda VIII, p. 393. — C.monogyna (non Jacq.) M. Pop.in Bull. Appl. Bot., Gen.a Pl. breed.

C.zangezura A. Pojark. sp. n. in Addenda VIII, p. 394. Shrub ca. 1.5m high, with slender, glabrous or slightly hairy dark brown shoots and dark gray branches; axillary leafless spines short, 7-10mm, nearly dark gray; leafy and leafless spines usually few; leaves dark green and slightly lustrous above, dull and somewhat lighter below, glabrous except for small furrows in angles of main veins and cilia on the margin; lower leaves on fruiting shoots elongate-obovate with narrowly linear base, from trifid at the apex to trilobate, the upper to 3.5cm long and broad, broadly ovate, with broadly cuneate, sometimes slightly rounded base, 5- partite, sometimes the upper lobe incised; lobes acute, with 1—3 large teeth at the apex, the lower lobe frequently with one incision; petioles ca. 2/3 as 352 464 long as the blade; notches cutting half-blade to My at the apex, near base to sik less often to 34 leaves on sterile shoots even more deeply dissected at base, their lobes unequally and coarsely dentate in upper part, often obtuse, broad; inflorescences apparently small, few-flowered; flowers unknown; fruiting: 2—6 fruits; branchlets glabrous; pedicels 6-9 cm long, glabrous or with few hairs; fruits ellipsoid, 6-9mm long, cherry- colored, with colored, rather succulent flesh, with nearly always 2, rarely 3 nutlets. Fr. September—October. Rocks, ravine slopes, among shrubs; solitary. — Caucasus: S. Transec. (Armenia near Goris in Zangezur). Endemic. Described from the Goris-chai Gorge (near Goris). Type in Leningrad. Note. With its small dark fruits and small, deeply dissected leaves, C.zangezura seems at first sight to be most closely related to C.beckeriana A.Pojark; however, it shows considerable differences which preclude any close relationship between them. The nutlet of C.zangezura is much flatter, with very slightly impressed, faintly out- lined furrows on the dorsal side; in contrast to the long-acuminate sepals of species of the series Stevenidnae, those of C. zangezura are short and broadly-triangular, not always divergent but sometimes erect- spreading. The characteristics indicated for the structure of the nutlet bring it close to that of C. pentagyna W. et K.; the reddish color of the fruit flesh and the straightly spreading position of the fruiting sepals, similar to that characteristic for C.pentagyna and often for its hybrids, suggests that C. zangezura may be a hybrid of the above-named species. If this assumption is taken as a working hypothesis, the difficulty then lies in determining the other possible parent species, for no more or less definite characters of any other S. Transcaucasian species — a fortiori of other species growing in the same distribution area under the same ecological conditions (C. schraderiana Ldb. and C. kyrtostyla Fingerh.) — have been observed in this hawthorn. C.zangezura is distinguished from all these species by much smaller fruits which, together with its small, deeply parted leaves, gives it its distinctive appearance. 36. C.schraderiana Ldb., Fl.

Fl. June, fr. from end of September. In Zangezur on stony slopes at the edge of oak-and-hornbeam forests, together with other shrubs, at 1,300—1,400m. — European part: Crim. (no specimen!); Caucasus: S.Transc., in Armenia and Zangezur (Goris, Shurnukhi, Sobukh). Described after a cultivated specimen of the Goettingen Botanical Garden, grown from seeds obtained from E.Crimea. Type in Leningrad. Note. C.schraderiana has distinctly expressed characters indicating its close relationship with C. orientalis Pall.: 1) fruits with wide umbilicus, sometimes flattened at the poles, usually with 4 or 5 nutlets of identical structure to those of C. orientalis, 2) pubescence of inflorescence and leaves identical to that of the latter species and even leaf shape and dentation very similar; however, the habitus of C.ori- entalis is entirely different, owing to the developed petioles and pedicels, characters which — like the dark color of the fruits — are not peculiar to species of the section Azaroli. This fact, as well as the sometimes observed straightly spreading position of the fruiting sepals, leads to the assumption that the second parent-species of C. schraderiana is the black-fruited C. pentagyna W. et K. At present, only C.pentagyna grows in the same distribution area (forest part, in Zangezur) as C.schraderiana,at least under the same ecological conditions. C.schraderiana has been cultivated in Europe for the past 100 years, although it seems to be rare (it is reported as C. sanguinea or C.orientalis). Lindley has published an excellent colored illustration of this species with an analysis of the fruit and a detailed description; taken together with the original specimen collected while flowering by Schrader, this leaves no doubt that this cultivated hawthorn is identical with the specimen from Zangezur. Economic importance. Ornamental, most beautiful during fruiting; fruits often very large, succulent and pleasant-tasting. 37. C.pseudoazarolus M. Pop. in Bull. Appl. Bot., Gen. et Pl. breed.

Fr. October. Ravine slopes.— Centr. Asia: Mtn. Turkm.: in Kopet Dagh. Endemic. Described from the Aidere Gorge. Type in Leningrad. Note. Distinguished from C.ambigua C.A.M. by its darker fruits with broader and shallower umbilicus, by different shape of sepals and leaves, and by its spiny shoots. The morphological characters of C.pseudoambigua lead us to believe that it is a hybrid of the red- fruited, monogynous C.turkestanica A.Pojark. with C. pseudo- melanocarpa M.Pop. (black fruits and 3—5 nutlets), viz.: fruits of C.pseudoambigua with a narrow high-rimmed umbilicus; the plants quite frequently monogynous as in the latter species (this is observed only exceptionally in species of the series Ambiguae); nutlets almost smooth on the sides. Inits leaves C.pseudoambigua very closely resembles C.turkestanica A. Pojark., differing only in the larger size and in the higher position and closer approximation of the lobes. Apparently the species named is the second parent species of C. pseudoambigua, whose true taxonomic status can be ascertained only as a result of field observations. 39. C.armena A.

Closely related to C.kyrtostyla Fingerh., from which it is distinguished by its leaves — pubescent on both sides — and by darker fruits; leaf lobes entire or with few large teeth at the apex,in C. kyrto- styla rather serrulate, at least from the middle.

The Russian term ''Srednyaya Aziya'' is, in English, Central Asia (or Soviet Central Asia). Therefore the term Middle Asia has been used for Russian ''Tsentral'naya Aziya,'' which is non-Soviet inner Asia, comprising western China (Sinkiang and Tibet) and Mongolia. 2. According to Russian usage, the European part of the USSR is "eastern Europe.'' Therefore 'western Europe’' includes the whole of Europe outside the USSR. 418 EXPLANATORY LIST OF ABBREVIATIONS OF RUSSIAN INSTITUTIONS AND PERIODICALS APPEARING Abbreviation BIN SSSR Bot. -geogr. issled. v Turkest.
