 2500 m., August 1907 (No. 3361; bush 2.5 m. tall, flowers Hlac); Hsing- 

 shan Hsien, 2000 m., July 1907 (No. 3361^; bush 1-2.5 m. tall, flowers

 3361^; bush 1-3 m. tall, flowers pale lilac, orange eye); Changyang 

 Hsien, thickets, alt. 1600-2500 m., July 1907 (No. 3361°; bush 3 m. 

 tall, flowers lilac-pink); without locality, July 1901 (Veitch Exped. 

 Nos. 2247, 2247*), A. Henry (Nos. 156% 2351 in part, 4689, 6193). 



Owing to inaccurate information supplied by one of Henry's Chinese coUectore, 

 this plant was originally described as a tree 20-30 ft. tall, with white flowere, 

 whereas it is a bush never exceeding 4 m. in height and the flowers are always 

 lilac colored. It is a variable species but may be easily distinguished from 

 B. Davidii Franchet which has four-angled stems by its round stems and small 

 flowers, with the stamens inserted immediately below the mouth of the corolla- 

 tube. 



Buddleia Hemsleyana Koehne differs only in the usually pubescent caljoc; in 

 this and in other respects it is intermediate between the type and the var. Giraldii. 

 Koehne describes his plant without an orange-colored corolla throat but in speci- 

 mens from cultivated plants before us we find this color present but covered by 

 the zone of villose hairs. To us the differences seem too slight to warrant the 

 separation of Koehne's plant from Hemsley's Buddleia albiflora. 



Buddleia albiflora is a common shrub in the mountain thickets up to 2500 m., 

 especially in open, moist situations. Henry's No. 10915, a fruiting specimen, from 

 Mengtze, Yunnan, probably belongs here.
