Palynology: — Pollen grains prolate, 21.14 (19.43 – 22.62) µm × 13.13 (12.33 – 14.22) µm, P / E ratio approx. 1.63 (1.59 – 1.73), radially symmetrical, isopolar, tricolpate; shape in polar view triangular.

Phenology: — Acronema crassifolium starts to grow leaves in May, flowers from July to August and fruits from mid-September to November. Habitat and distribution: — Acronema crassifolium is endemic to northern Yunnan, southwest China; up to now it has only been collected at three localities (Figure 5). The new species usually grows in alpine meadows and the understory of Abies forests and Rhododendron thickets, at elevations of 3500 – 4000 m a. s. l.	en	WANG, HUAN-CHONG, ZHOU, XIN-MAO, SUN, HANG, WANG, YUE-HUA (2013): Acronema crassifolium sp. nov.
