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: KiatingFu, June 1903 (Veitch Exped. 

 No. 4066; 4 m. 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 .eaves 

 this variety agrees exactly with the type and therefore I cannot consider it an /thing 

 else but a variety of S. dasyanthus.
