Corispermum gelidum Iljin, Fl. USSR 6: 875 (1936). Holotype: [TAJIKISTAN] In ditione lacum Rang-kul, prope vallem Zor-Burljuk [nr Rang-kul Lake, Zor-Burlyuk valley], 29 Aug 1935, H. Raikova s.n. (TASH - photo! isotype LE!).
= C. pamiricum Iljin var. pilocarpum Tsien & C.G.Ma in Kung & al., Acta Phytotax. Sin. 16(1): 118 (1978) syn. nov.
Lectotype
(Sukhorukov, designated here): CHINA, Xizang, Rutog (Ritu) County, Rabang (Rebang), in lakeside sands, 4360 m a.s.l., 28 Aug 1976, Qinghai-Tibet Team Vegetation Group 13656-B (PE00024045! isolectotype PE00640936!).
Taxonomic notes.
Corispermum gelidum and C. pamiricum var. pilocarpum are synonymised here for the first time due to the presence of stellate hairs on the fruit surface. Other anatomical characters of the fruit are similar and overlapping (compare with Sukhorukov 2007b, Sukhorukov et al. 2014). However, the authentic specimens of C. pamiricum var. pilocarpum possess a small (ca. 0.15 mm) fruit wing, whereas the type specimen of C. gelidum has a prominent (0.3-0.4 mm) wing.
Description.
Annual up to 20 cm, glabrescent. Leaves linear to narrowly oblong, up to 3.0 × 0.5(0.7) cm. Inflorescence short. Bracts shorter than leaves, lanceolate, (almost) completely covering the fruit, appressed to the stem. Fruit 2.6-3.5 × 1.7-2.0 mm, 0.40-0.60 mm thick, flat or folded adaxially, with triangular apex terminating in slightly emarginate beak, with stellate hairs and mostly warty (Fig. 36C View Figure 36 ), sometimes with groups of dark-brown tanniniferous cells. Wing 0.15-0.45 mm, entire to dentate, broadly triangular in cross-section. Sclereids in the medium fruit part composed of 1-2 layers located parallel to the fruit axis.
Habitat.
Sandy places at altitudes of 3500-4800 m.
Phenology.
Flowering: July-September; fruiting: August-October.
Distribution.
