Type: — CHINA . Tibet [Ngari pref.] 32°31′N 80°04′E , Shiquan [Sênggê] River , alt. 3800 m , 3 August 1984 , Zhengxi An 1-10092 ( holotype XJA ! as C. montanum ) ( Fig. 7 ) . Diagnosis: — C. dutreuilii var. montanum differs from the nominal variety by the stellate pubescence and the thickness of the fruit ( 0.6–0.8 mm ) in comparison with the type variety which has glabrous fruits with thickness 0.3–0.4 mm . FIGURE 7. Holotype of C. dutreuilii var. montanum (XJA) . Ecology and distribution: —Sandy river basins. The new variety is known only from the locus classicus ( Fig. 3 ). IUCN Red List Category: —The appropriate data on abundance and/or distribution of the taxon is lacking. It can be included in the Data Deficient (DD) as well as Not Evaluated (NE) categories of IUCN Red List categories ( IUCN 2010 ) as there is inadequate information to make a direct or indirect assessment of its risk of extinction based on its distribution and/or population status. Taxonomical notes: —As in the nominal variety of C. dutreuilii Iljin (Iljin 1937) , the new variety is almost glabrous, up to 25 cm tall, branched from the base. Leaves lanceolate or oblong, to 5 mm wide, bracts almost completely covering the fruits. Inflorescence loose, basally often interrupted. Fruit triangular at apex, 3.5–3.8 × 2.2 mm , with conspicuous wing 0.5–0.8 mm , with stellate pubescent fruits.
