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 c" 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.

Asstated 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 c? catkins are very short-stalked and from 3 to 6 em. long; the fruiting aments 
are up to 8 cm. in length and 1 em. 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 little 
recurved.

On account of the two glands of the c? 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 1n >- 
psilostigma Andersson; the solitary gland is about half as long as the ovary; the 
Fours or roundish bracts are glabrous within, and in the male plant lobulate- 
denticulate.
