42 WILSON EXPEDITION TO CHINA 
subpycnostachya, 9; and No. 751, ex Burkill); valley of Jerikhou, 
J.A. Soulié (No. 509, ex Burkill). Sikkim: Lachen, “alt. 12000 ped.,” 
J. D. Hooker (type of S. myrtillacea; with fruits). 
There is no marked difference between Pratt’s No. 835 and Wilson's No. 2161. — 
Both closely resemble the co-type in Herb. Gray of Andersson's S. myrtillacea; — 
the descriptions, too, of both authors agree very well. The ovaries are very short- 
stalked or subsessile in all the three specimens before me, the pedicels being about 
half as long as the gland. The styles are more or less elongated and are as long or 
longer than the oblong stigmas. The bracts are acutish, more or less silky, and 
often glabrous at the apex on the outside. The leaves are glabrous or very soon 
become glabrous and are oblanceolate or elliptical, mostly acutish at the ends and 
entire. I have not seen mature leaves; in Andersson's type they measure up to 3 
em. in length and 1.5 in width, the petioles being very short (1-2 mm.). The flat 
appressed acutish leaf-buds are alike in both the types; the purplish-black color 
of the somewhat pruinose branchlets is the same in all the specimens.
