Cremanthodium farreri Smith (1920: 202) . Figs. 2 , 3

Type :— Bordering area between northwestern Yunnan, China and northeastern Myanmar. Chimili Pass, 12500−13000 feet (= 3810−3962 m), 1 August 1919, R. Farrer 1178 (E!, only the lower plant with a capitulum, lectotype designated here; isolectotype E!). Fig. 2A, B .

For a full description of this species see Smith (1920) (excluding the description of the shape of basal leaves), Good (1929), Liu (1989), Min (2004), and Liu & Illarionova (2011).

Distribution and Habitat: — Cremanthodium farreri is distributed in northwestern Yunnan (Fugong, Gongshan, Lushui), China, and also in northeastern Myanmar ( Fig. 9 ). It grows in alpine meadows or on grassy slopes at elevations of 3350−4400 m above sea level.

Phenology: —Flowering July to August; fruiting September.

Additional specimens examined: — CHINA. Yunnan: Fugong, Anonymous 80147 (HITBC), Bijiang Exped. 1117 (KUN), Gaoligong Shan Biodiversity Survey 26420 (CAS, PE), Nujiang Exped. 0832 (KUN), H.T.

Note: — Good (1929) mentioned that three Forrest collections, 20228 (E, P, PE), 22820 (E), 22828 (E), were possibly all old specimens of Cremanthodium farreri , but could not be determined accurately. The three gatherings were all made from Gongshan, northwestern Yunnan, China, and actually belong to C. phyllodineum Liu (1984: 60) . The specimen Forrest 20228 (PE) was cited by Liu (1984) as one of the paratypes of this species.
