Western Szech'uan: west of Kuan Hsien, Pan-lan-shan, upland 
thickets, alt. 3300 m., October 1910 (No. 4354, type; bush 2-3.6 m.; 
with fruits; No. 4356; sterile); Mupin, alt. 1600-2000 m., June 1908, 
(No. 1402; bush 2.4-3.6 m.; with fruits). 
Mr. Wilson sent cuttings of both No. 4354 and 4356 to the Arnold Arboretum. 
Plants raised from these agree exactly; the twigs get black in drying, and the leaves, 
which do not differ from the larger ones in No. 4356 and measure up to 5 cm. in 
length and 1.8-2.5 em. in width, are nearly sessile. No. 1402 is a little more pubes- 
cent, but has the same kind of long buds. The leaves are nearly as narrow as 
those of the type specimen and measure up to 4 cm. in length and to 1.2 in width. 
In its leaves and buds the species looks very distinct, but is certainly nearly re- 
lated to S. cathayana Diels. 
The specific name is derived from paxpés, long, and BAacrós, bud.
