GALATELLA BECTAUATENSE (ASTERACEAE), A NEW SPECIES FROM CENTRAL KAZAKHSTAN
GALATELLA BECTAUATENSE (ASTERACEAE) - НОВЫЙ ВИД ИЗ ЦЕНТРАЛЬНОГО КАЗАХСТАНА
Summary. In this paper we describe and illustrate Galatella bectauatense as a new species from Central Kazakhstan, morphologically similar to G. fastigiiformis.
Key words: Galatella bectauatense, G. fastigiiformis, G. saxatilis, granitoids, new species, Central Kazakhstan. Аннотация. В статье описывается и иллюстрируется новый вид - Galatella bectauatense из Центрального Казахстана, морфологически близкий к G. fastigiiformis.
Ключевые слова: Galatella bectauatense, G. fastigiiformis, G. saxatilis, гранитоиды, новый вид, Центральный Казахстан.
Introduction. The Bektauata Mountain is situated in the south of Kazakh Uplands, 70 km north of Balkhash. Z.V. Karamysheva and E.I. Rachkovskaya (1973) referred this territory to Central Kazakh subprovince, Near-Balkhash geobo-tanical district. It represents vast riverine and inter-hummock plains with a complex of light chestnut and alkali soils formed on them. The zonal vegetation is represented by communities of Artemisia-Stipa steppes. The Bektauata Mountain is composed of granitoids of Paleozoic origin (fig. 1). The mountains are dissected with deep ravines, there are springs from the northern side that are characteristic for granite masses. This favours colonization and preservation of many mesophytic species. Location of the Bektauata Mountain at the border of steppe and semi-desert zones, its relative proximity to the mountains of Altai and Dzungaria determine flora peculiarities (Kupriyanov, Khrustalyova, 2010).
Seclusion of Bektauata granite mass has conditioned high endemism. N.L. Semiotrocheva described new species Linaria bektauatensis Semiotr., L. dmitrievae Semiotr. (Semiotrocheva, 1965). Regular botanical investigations in the area of the Bektauata Mountain and some other granitoid masses resulted in discovery of a new species of the genus Galatella Cass.
The genus Galatella comprises 35-45 species common for South and Middle Europe and for the most part of Asia. V.I. Terekhova (1965) reports 15 species for Kazakhstanian flora. The only small-leaved species from Middle Asia (narrow endemic), G. saxatilis (Popov ex Novopokr.) Novopokr., was described by I.V. Novopokrovsky based on the specimens collected by M.G. Popov, and diagnos-tically it is most close to the species we describe. We think it is necessary to describe a new species and not to classify relevant gatherings as G. saxa-tilis. First, G. saxatilis differs (diagnostically) from other Galatella species by its life form. This plant is considered to be a semi-shrub. This is the only Galatella species with such life form. Secondly, we could not find the specimens with such characteristics in any herbarium where the materials of both Novopokrovsky and Popov are deposited (AA, TK, LE, TASH, TAD, RW, NS, NSK, KW). Besides, N.N. Tsvelev (1959) mentioned that the type specimen of this species has not been found yet. Until now, we have found neither the type material nor any other collection with author's note which could be considered as original material of G. saxatilis.

Isotypes: № Kaz02815 (KUZ); № Kaz 02816 (KUZ); № Kaz02818 (NS).
Perennial herb 35-45 (60) cm tall. Stems solitary or few, covered with short papillary hairs, thin tomentum and sparse glandular hairs; erect, branched from base, with few branches at the top ending with one or rarely two anthodes (fig. 3, 4).
Leaves lanceolate, linear-lanceolate, sessile, up to 2.5 cm long and up to 3 mm wide, sharply reducing in size in inflorescence. Lower leaves slightly narrower at the base, upper leaves almost amplexicaul, short cuspidate. Lower and young leaves with three nerves, lateral nerves of leaves in the middle portion of stem are visible only at their base. Both sides of leaves covered with mat dotty glands, papillary hairs and matted tomentose pubescence.
Anthodes in loose corymbose inflorescence 1.2-2.0 cm diam., involucres widely obconical, herbaceous, greenish, pubescent; outer leaflets of involucre covered with thin tomentum on dorsal side, inner leaflets almost glabrous with adpressed hairs, narrowly membranous-ciliate along edges (fig. 5).
Ray flowers (6-8) pinky-violet, sterile, sometimes with rudimentary style; disk flowers (20-24) yellow, incised to third, style appendages bilobate, almost as long as style branches.
Achenes 3.0-3.5 mm, oblong to lanceolate, densely pubescent, pappus hardly exceeds disk florets and is composed of large amount of brownish serrated flexuose bristles.
Affinity. Galatella bectauatense is morphologically similar to G. fastigiiformis Novopokr., but differs from the latter species mainly in its conspicuous xeromorphic habit, a small number of heads,

smaller leaves up to 2.5 cm (not to 6 cm), strongly reducing in size in the inflorescence up to triangle-lanceolate; stems branched almost from the base; divaricate upper inflorescence shoots; lower amount of disk florets.
Distribution and habitat. Distribution area of the species covers transitional zone between the steppe zone and northern deserts (fig. 6). The species is stenotopic since all locations are confined to fissures in granite rocks.
Многолетнее травянистое растение 3545 (60) см. Побеги одиночные или в небольшом числе, покрытые короткими сосочковидными волосками, тонким паутинистым войлочком и редкими железистыми волосками, прямостоячие, от основания ветвистые, на верхушке растопырено разветвленные, с немногочисленными веточками, заканчивающимися одной, реже двумя корзинками.
Листья ланцетные, линейно-ланцетные, сидячие, до 2,5 см дл. и до 3 мм шир., резко уменьшающиеся в соцветии, нижние к основанию слегка суженные, верхние почти стебле-объемлющие, коротко заостренные, нижние и молодые с тремя жилками (боковые жилки у средних стеблевых листьев заметны только у основания листа), с обеих сторон покрыты ту-

Корзинки в рыхлом щитковидном соцветии 1,2-2,0 см в диам., обертки широко-обрат-ноконические, травянистые, зеленоватые, опушенные; внешние листочки обертки на спинке покрыты тонким войлочком, внутренние - почти голые, с редкими прижатыми волосками, по краю узко-перепончато-реснитчатые.
