Chamaesium woffianum Fedde ex Wolff (1930: 305)

Trachydium yunnanense (Fedde ex Wolff) Hiroe (1979: 714) View in CoL , nom. illeg. ( Fig. 9 View FIGURE 9 )

Type: CHINA. Yunnan: Mekong-Yangtze divide, 11000 ft. (About 3350 m), open stony pasture, August 1914, G.Forrest 13011 (lectotype: E00000264!, designated by Pimenov 2017: 132; isolectotype: PE00033252 !) .

Notes: — Chamaesium wolffianum usually possess obsolete bracteoles and bracts, linear segments of leaves, greenish petals, and fruits with slight undulate ribs. The shape of linear segments of leaves is obvious character to distinguish it from other Chamaesium species.

Distribution in China: — Yunnan. Endemic. ( Fig. 3 View FIGURE 3 )

Habitat: — Chamaesium wolffianum lives in the forests and shrubs. It usually occupied humid areas at an elevation of ca. 3700 m.

Specimens examined: — CHINA. Yunnan: Shangri-La Xian , 25 August 1959, G.M.Feng 23222 (KUN) ; Shangri-La Xian, Mt. Haba , 28 August 1962, Zhongdian Team 1558 (KUN) ; Shangri-La Xian, Lake Shudu , 3700 m, 20 August 2016, X.L.Guo & Q.Y.Xiao GXL16082001 (SZ) .
