STYRACEAE. 
Determined by ALFRED REHDER. 
STYRAX L. 
Styrax dasyanthus Perkins in Bot. Jahrb. XXXI. 485 (1902); in 
Engler, Pflanzenr. IV.-241, 31 (1907). 
Western Hupeh: A. Henry (No. 5977, type); north and south of 
Ichang, thickets, alt. 300-1000 m., June and October 1907 (No. 372, 
in part; bush or small tree, 2-8 m. high, flowers white); Hsing-shan 
Hsien, ravines, rare, alt. 500 m., June 4, 1907 (No. 2572; large bush, 
8 m. high, flowers pure white, fragrant); without precise locality, 
June 1901 (Veitch Exped. No. 1106); Chienshi, July 1900 (Veitch 
Exped. No. 1275, in part (flowering specimen); tree 3 m. high, flowers 
white). Western Szech’uan: Kiating Fu, June 1903 (Veitch Exped. 
No. 4066; 4m. high). 
No. 2572 differs from the type in having the lower surface of the larger and broader 
leaves sparingly furnished with small fascicled hairs, and forms thus a transition 
to the following variety. In No. 4066 the leaves are broader and thinner and less 
closely veined than in the type and the inflorescence is looser. 
Styrax dasyanthus, var. cinerascens Rehder, n. var. 
A typo recedit foliis subtus initio dense albido- v. cinereo-tomentosis 
demum plerumque sparsius pilis stellatis conspersis, sed in foliis superi- 
oribus innovationum tomento denso albido persistente praeditis. 
Western Hupeh: Chang-lo Hsien, thickets, ravines, etc., alt. 
600-1000 m., May and June 1907 (No. 2571, type; bush 5 m. high); 
Hsing-shan Hsien, alt. 300-600 m., June 6, 1907 (No. 372°; tree 
10 m. high, flat-topped, flowers white, fragrant); Chien-shi, July 1900 
(Veitch Exped. No. 1275, in part; fruiting specimen). 
In general appearance, in the flowers and in the shape and venation of the leaves 
his variety agrees exactly with the type and therefore I cannot consider it anything 
else but a variety of S. dasyanthus.
