72 WILSON EXPEDITION TO CHINA 



subpycnostachya, 9 ] and No. 751, ex Burkill); valley of Jerikhou, 

 J.A.Soulie (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 

 cm. 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.
