STYRACE AE . — STYRAX 291 



type); Kiangsi: Ruling, side of streams, alt. 1300 m., July 29, 1907 



(No. 1734). 



The specimen from Kiangsi apparently belongs here, though it is without flowers 

 or fruits; it bears the same large galls as are found in S. Benzoin Dryander and other 

 species.

Western Hupeh: Changyang Hsien, woods, common, alt. 1300- 

 2000 m., June 1907 (No. 2574; tree 6-10 m. high, flowers white); 

 South Wushan, June 1900 (Veitch Exped. No. 915); without precise 

 locality, A. Henry (Nos. 5676, 5977, 6895). Western Szech'uan: 

 Wa-shan, thickets, alt. 2000-2700 m., June 1908 (No. 2578; tree 5-8 

 m. high, flowers white); Nanch'uan, A. v. Rosthorn (No. 2078). 



No. 2578 differs from the type in the somewhat larger flowers and shorter racemes, 

 also in the generally narrower leaves which are finely denticulate. 



Styrax Hemsleyanus, var. griseus Rehder, n. var. 



A typo recedit foliis subtus laxe pilis stellatis griseis facile deter- 

 gendis obtectis supra sparsius pilis stellatis conspersis, petiolis 

 et axibus inflorescentiae stellato-tomentosis, calyce brunneo-fusco- 

 tomentoso. 



Western Hupeh: Changyang Hsien, woods, alt. 1300-2000 m., 

 June 1907) No. 2574*; tree 6-10 m. high, flowers white). 



Though at first sight this form looks rather distinct, I am not able to find any 

 other character except the pubescence to separate it from typical S. Hemsleyanus; 

 the leaves are rather large, 10-13 cm. long and 7-8.5 cm. broad and only finely 

 denticulate.

Western Szech'uan: Ta-hsiang-ling, Chingchi Hsien, thickets, 

 alt. 1000-1300 m.. May 1908 (No. 2577; bush 2-3 m., flowers white); 

 Mupin, thickets, alt. 1000-1300 m., June 1908 (No. 2575; largo bush 

 3-7 m. high); Wa-shan, rare, alt. 2800 m., July 1903 (Veitch. Exped. 

 No. 4065, type; bush 3 m., flowers white). 



The flowers are white according to Wilson's notes on the labels, though in the 

 dried state they have a pinkish hue which also appears in specimens of other specieB, 

 The bright orange-yellow color of the calyx and of the winter-buds seems to be 

 characteristic of this species.
