116 WILSON EXPEDITION TO CHINA 



The typical S. Daltoniana is easily distinguished by the brownish pubescence 

 mixed with white of the lower surface of the elliptic-lanceolate indistinctly crenulate- 

 dentate leaves, the short cf catkins, the bracts of which are oblong and truncate 

 and denticulate at the apex, and by the long female catkins. In the 9 flowers 

 with their large bracts and the long deeply cleft style S. Daltoniana much resembles 

 S. Ernesti Schneider and other species of sect. Eriostachyae,

INDIA. Assam : " Khasi Hills, 4-5000 ped.," J. D. Hooker & Thomson (type 

 of S. eriophylla, of which I have seen only a sterile branch ; the type of S. psilostigma 

 was collected by Jacg'weTOoni in India). Sikkim : "reg. temp. 5-8000 ped.," J. D. 

 Hooker (type of 5. viminalis, var. Smithiana, a doubtful sterile form). Eastern 

 Bengal: without locality, W. Griffith (No. 4500; &). 



As stated above, p. 51 , the specimen from Hupeh resembles S. phaidima Schneider 

 in its pubescence, but agrees with S. psilostigma Andersson in its short petioles and 

 short aments. The typical *S. psilostigma has a dense silky and woolly pubescence; 

 the <f catkins are very short-stalked and from 3 to 6 cm. long; the fruiting aments 

 are up to 8 cm. in length and 1 cm. thick; the style is deeply cleft and hidden at the 

 base by the hairs of the ovary. The stigmas are bifid, oblong and often a Uttle 

 recurved.

On account of the two glands of the cf flowers I put this species in this section. 

 It differs from the other species, however, in being a very small shrub with small 

 lanceolate-elliptic leaves. The ovaries and styles are much the same as in S. 

 psilostigma Andersson; the soHtary gland is about half as long as the ovary; the 

 broad-ovate or roundish bracts are glabrous within, and in the male plant lobulate- 

 denticulate.
