Wilson’s and Purdom’s plants belong to the same species, but Fedde’s description 
agrees well enough with the specimens before me. It was drawn from a flowering 
plant only with probably rather young flowers because the author says: “ flores 
circiter 3 mm. diamet." The living plants in this Arboretum look somewhat dif- 
ferent from those of the preceding species, forming a more spreading, loosely branched 
shrub. The leaves are mostly narrowly elliptic and acute, but those of the vigorous 
young shoots are much more obtuse and broader, and more distinctly whitish 
beneath. The inflorescences are variable, being shorter and almost fasciculate- 
racemose at the top of the branches and longer and more or less paniculate at the 
base. The fruitshave avery short, sometimes very indistinct style. It needs further 
investigation to determine if B. Dielsiana represents a good species or only a 
variety of B. Henryana. Wilson's plant from western Szech'uan when fully known 
may even represent another distinct variety. <

Western Szech'uan: northeast of Tachien-lu, thickets, alt. 2800—3100 m., 
July 9, 1908 (No. 2862; bush 1.8-2.4 m. tall; flowers yellow). 
Wilson's specimen consists of old branches with very straight, apparently up- 
right, 4-13 em. long inflorescences which in the somewhat verticillate arrangement 
of the rather small flowers are similar to those of B. dasystachya Maximowicz. 
The leaves are almost entire or very indistinctly serrate. The type, A. von Ros- 
thorn's No. 2044, was collected in Nanchuan, southeastern Szech'uan, and has the 
same kind of inflorescences the flowers of which had fallen, and the fruits are un- 
known. The leaves are similar in shape but distinctly serrulate. I described the 
racemes as pendent, but probably they are upright. The flowers of Wilson's speci- 
men are about 5-7 mm. wide and similar to those of B. dasystachya, and I sup- 
oes that B. Feddeana may rather belong to the following than to the section 
gares. 
Here may be added the following species representing in my opinion a distinct 
section:

The type of B. dolichobotrys was collected on the Tai-pei-shan, and I cannot 
detect in Fedde's description any character sufficient to separate his species
