ADDITIONAL KEYWORDS: Cruciferae – Pangong – Rupshu – taxonomy. INTRODUCTION Within the family Brassicaceae, Draba with c. 350 species currently accepted (Appel & Al-Shehbaz, 2002; Koch & Al-Shehbaz, 2002) is one of the largest genera, with most species occuring in alpine and arctic regions. The notorious taxonomic complexity of the genus, caused by autogamy and polyploidy (Brochmann, 1992; Scheen, Elven & Brochmann, 2002), is shared with other groups confined to harsh environments. There is a paucity of diagnostic characters because of the dwarf habit of plants and reduction in the number, size and complexity of individual plant organs. In Central Asia, the Himalayas and Tibet, Draba has also been undercollected because of the limited accessibility of the high altitudinal areas, which are often situated close to politically sensitive national borders. Consequently, new collections from the Himalayas and neighbouring mountains still include undescribed species (e.g. Al-Shehbaz, 2002b, 2004). The number of Draba species accepted in the literature focusing on individual regions of the Western *Corresponding author. E-mail: klimes@butbn.cas.cz Himalayas is about 30. For example, in the recent treatment of Draba in Jammu and Kashmir State, 21 species were listed (Rajeswari, Uniyal & Singh, 2002). Similarly, Jafri (1974) reported 23 Draba species from Pakistan and Kashmir. For all of India, Henry & Janarthanan (1993) included 33 species, of which 21 are known from Jammu and Kashmir. Records of several species are based on few specimens or even only one, and misidentifications are relatively frequent in herbaria. The entire genus urgently requires revision. In spite of these difficulties, distinct and well-delimited species can still be found in the Western Himalayas (e.g. Al-Shehbaz, 2002b). While working on the Flora of Ladakh, several novelties were recorded at extreme altitudes of eastern Ladakh (e.g. Al-Shehbaz, 2002a), an area geographically belonging to the Tibetan plateau. Some of the new or rarely recorded species are common at altitudes between 5600 and 5900 m, but rarely descend below 5500 m. So far, about a dozen flowering plant species have been recorded in Ladakh at altitudes above 5500 m. However, recent field studies revealed that at least 120 species occur at these altitudes (L. Klimeš, unpubl. data). This indicates that collecting effort at the high altitudes of Ladakh and in neighbouring © 2008 The Linnean Society of London, Botanical Journal of the Linnean Society, 2008, 158, 749–754 749 750 L. KLIMEŠ and D. GERMAN areas of western Tibet has been too low to provide satisfactory estimates of species composition and diversity. Therefore, it is not surprising that undescribed species can still be found in these remote areas. Here, we report a striking yellow-flowering cushion Draba species, discovered in eastern Ladakh by the first author in July 2000 and repeatedly observed in the field in 2001, 2002 and 2003. Comparisons with specimens in the herbaria BSD, K, LE, WII, P, W and WU and studies of original descriptions showed that the collected specimens can be recognized as a new species.

Distribution and conservation status: So far known from two small areas north of the Indus River, about 90 km apart (Ladakh Range; border between Leh and Shyok regions according to Dickoré, 1995) and one larger area south of the Indus River and east of the Tso Moriri Lake (Rupshu region according to Dickoré, 1995), situated 45 km apart. Its presence in east Rupshu and western Tibet is expected. Most localities of the species are at altitudes above 5700 m, where grazing intensity is low (yaks, pikas) and presence of humans is infrequent (tourists, nomads crossing the mountain ranges). Therefore, the species does not seem to be under any threat. Etymology: The species is named in honour of Ihsan A. Al-Shehbaz, an expert on Brassicaceae of the world, particularly Asian Draba species. Iconography: Figure 1. Habitat: Draba alshehbazii is a chamaephyte, restricted to the free solifluction subnival zone at altitudes of 5470 to 6000 m, with most localities situated above 5700 m. The only locality at a lower altitude (at 5310 m) is 90 km west of the other localities, where altitudinal belts are shifted towards lower altitudes as a result of lower continentality and higher precipitation. At altitudes above 5700 m, D. alshehbazii is a common species, forming relatively large 751 and compact cushions and colonizing flat areas and gentle slopes (usually <15°), growing on solifluction soils, often with some slate gravel, in outer parts of soil polygons, the soils being mesic, never waterlogged or very unstable. It is most frequently accompanied by Alyssum klimesii Al-Shehbaz, Aphragmus oxycarpus (Hook.f. & Thomson) Jafri, Arenaria bryophylla Fernald, Desideria pumila (Kurz) Al-Shehbaz, Draba altaica Bunge, Draba oreades Schrenk, Eritrichium hemisphaericum W.T.Wang, Poa attenuata Trin., Potentilla pamirica Th.Wolf, Saussurea glacialis Herder, Saussurea gnaphalodes (Royle) Sch.Bip., Saussurea hypsipeta Diels, Saxifraga nanella Engl. & Irmsch., Stellaria decumbens Edgew., Thylacospermum caespitosum (Camb.) Schischk. and Waldheimia tridactylites Kar. & Kir. Draba alshehbazii often occurs together with one or several other species of Draba, most frequently with Draba altaica, Draba glomerata Royle, Draba himachalensis Al-Shehbaz and D. oreades, but sometimes also with Draba lasiophylla Royle and Draba ludlowiana Jafri (conspecific with Draba stenobotrys Gilg & O.E.Schulz, as suggested by I. Al-Shehbaz, unpubl. data). The simplified key on the next page can be used to identify D. alshehbazii in Ladakh: Several other species are given in the literature from Ladakh: records of Draba alpina L. possibly belong to D. oreades Schrenk, from which it is not always separated (Nubra – Kachroo et al., 1977; Suru valley – Chaurasia & Singh, 2001; Zuildo, Suru Valley – White, 1983). However, true D. alpina is distributed in northern Canada and Alaska, Europe, Siberia, the Far East and Mongolia (Zhou et al., 2001). Draba fladnizensis Wulfen has been reported from Zanskar and Rupshu (Stewart, 1972) and from Nubra [Kachroo, Sapru & Dhar, 1977; synonym D. glomerata Royle]. True D. fladnizensis is likely to be absent in China (Zhou et al., 2001) and its occurrence in the western Himalayas is also unlikely. Draba incana L. has been reported from the Lower Shyok valley (Chalunka) by Chaurasia & Singh (1996) and from Nubra and Zanskar by Kachroo et al. (1977). However, this species is restricted to Europe and North America (Zhou et al., 2001). Records from Ladakh may belong to D. lanceolata, D. lasiophylla (cf. Zhou et al., 2001) or D. tibetica. Draba korshinskyi Pohle was reported from Chang La by Singh, Singh & Uniyal (2002), based on H.J. Chowdhery & B.P. Uniyal 86140 (BSD!), which clearly belongs to D. oreades. Another record of this species from Nubra (Naqshi, Malla & Dar, 1989) is doubtful. The last species, D. trinervis O.E.Schulz, has been reported from Chang La by Singh et al. (2002), based on M. V. Viswanathan 55601 (BSD!). However, this specimen and its duplicate belong to Stellaria decumbens Edgew. © 2008 The Linnean Society of London, Botanical Journal of the Linnean Society, 2008, 158, 749–754 752 L. KLIMEŠ and D.

By the set of characters (yellow petals, leafless stem, few-flowered inflorescence, indumentum made up of forked and stalked, stellate trichomes, broad and short fruits with fewovuled ovary), D. alshehbazii belongs to series Alpinae Tolm. (type species D. alpina), which comprises about a dozen species with a predominantly circumpolar distribution, some of which occur in the mountains of north and central Asia (D. oreades, D. ochroleuca Bunge etc.). The new species resembles D. oreades in its life form, petal colour and, to some degree, in fruit shape, but is easily distinguished from it by the smaller size of nearly all parts, by the lack of simple trichomes on the leaves and the presence of soft, forked and substellate trichomes with branched rays (with 5–8 terminal rays) on leaves and sepals, compressed fruits, and persistent sepals. In contrast, trichomes on leaves and sepals of D. oreades are coarse, simple, forked and stellate with predominantly unbranched rays [with no more than 4(–5) terminal rays], fruits inflated at the base and caducous sepals. The indumentum density in the new species is considerably higher and the plant is greenish-yellowish canescent, whereas plants of D. oreades are always bright green. In plant size and petal colour, D. alshehbazii resembles D. involucrata (W.W.Sm.) W.W.Sm. (southern China – Sichuan, eastern Xizang and Yunnan; Zhou et al. 2001), from which it differs in life form (compact cushion, not forming loose pleiocorms), in indumentum of the adaxial side of the leaves (uniformly tomentose throughout except for proximal, adaxial part, not glabrous or sparsely tomentose), structure of branched trichomes (soft, long-stalked, forked and 3-rayed substellate with branched rays, not rigid, short-stalked to subsessile, forked or 3–4-rayed stellate), persistent (not caducous) sepals, petals (2-)2.3-2.5 ¥ 0.8-1.0 mm, apex rounded (not 2.54.5 ¥ 1.5-3 mm, apex emarginate), fruit apex and base acute to subacute (not obtuse), number of ovules (4–6, not 8–16 per ovary) and geographical distribution. Draba alshehbazii can be readily distinguished from other Draba species in the field, even if sterile, by its greenish-yellowish colour, which contrasts with the bright green rosettes of D. oreades and D. altaica and the dense snow-white indumentum of D. glomerata, D. himachalensis and D. ludlowiana. 753 ACKNOWLEDGEMENTS We are grateful to the staff of the herbaria visited (BSD, CBFS, K, LE, WII, P, PR, W, WU) for their kind assistance.
