All leaves discolorous, abaxially grayish white and densely or sparsely tomenta, adaxially green, rough, and densely or sparsely covered with ca. 0.5 mm spinules. Capitula corymbose, erect. Involucre campanulate, 3–3.5 cm in diam., glabrous. Phyllaries imbricate, in ca. 8 rows, straight, appressed; outer and middle phyllaries elliptic to lanceolate, 8–25 × 2–3 mm, margin above base expanded into yellowish, scarious lacerate wings, apex narrowed into a spine, shorter than inner ones; inner phyllaries lanceolate to linear, apically expanded into a short and narrow, acuminate, and spine-tipped appendage. Florets bisexual. Corolla purplish red. Achene ca. 4.5 mm. Pappus bristles yellowish, ca. 1.6 mm.

Phenology: —Flowering from July to October.

Distribution and habitat: — Cirsium nishiokae is distributed in China (Tibet), India (Darjeeling) and Nepal. It mainly grows on grass slopes at elevations of 2500–3900 m above sea level.

Notes: — Cirsium chrysolepis Shih was described on the basis of one collection, Xizang Exped. Pl. Med. 1575 (PE, Fig. 5 D View FIGURE 5 , Fig. 6 A View FIGURE 6 ), from Nyalam, Tibet, China. In the protologue, the author did not compare it with any species, but in Flora Reipublicae Popularis Sinicae, Shih (1987) stated that it was close to C. flavisquamatum Kitamura (1974: 16) , a species from Nepal, but differed by leaves discolorous, abaxially grayish white and densely or sparsely tomentose. But he neglected C. nishiokae Kitamura , a widespread species in Nepal and India. Cirsium nishiokae was described on the basis of one collection, H. Hara s.n. (TI, Fig. 6 A View FIGURE 6 ), from Darjeeling, India. Trough examination of the type materials and other specimens, we found that C. nishiokae and C. chrysolepis have no obvious differences in main traits between their type specimens, but there are some differences in the density of spinules on the abaxial leaf surface. But this feature is very variable in Cirsium . For example, there is a continuous variation from sparse to dense on the abaxial leaf surface of C. lipskyi . Cirsium nishiokae is distributed in Nepal and India at altitudes of 2500–3900 m, while C. chrysolepis is only found in Nyalam, Tibet, China at an altitude of 3500 m, where it is very close to the border to Nepal ( Fig. 7 View FIGURE 7 ). Therefore, we think they belong to the same species and treat C. chrysolepis as a synonym of C. nishiokae .
