152 WILSON EXPEDITION TO CHINA 
Probably U. Faurie’s No. 178 from Korea, June 26, 1906, “in monte des diamants" 
belongs to this variety. 
In var. cinerascens the young branchlets are pubescent, as are the leaves on both 
surfaces. To var. cinerascens may belong S. vagans, f. hurica Siuzev (in 
.Trav. Bot. Mus. Acad. Sci. St. Pétersbourg, IX. 88 [1912]; in Fedde, Rep. Spec. Nov. 
XIII. 328 [1914]. — Toepffer, Salicol. Mitt. No. 5, 248 [1912]), the leaves of which 
are glabrous on the upper side. : 
The species as a whole is extremely variable, and may be distinguished, from 
S. Caprea Linnaeus and the other related species by its short petioles, hardly 
more than 5 mm. in length, and by its mostly obovate-lanceolate leaves, which are 
more or less attenuate at the base and pointed at the apex. The flowers are 
much like those of S. Caprea Linnaeus.

AFGHANISTAN. Kurrum Valley, 1879, J. E. T. Aitchison (No. 574; fruits). 
This is a doubtful species of which I have seen branchlets with 9 and c? flowers 
of the type. According to Andersson’s description and my own observations S. 
insignis looks somewhat intermediate between sect. Capreae (Salix Wallichiana) 
and sect. Daphnoideae (Salix daphnoides), but on account of the ? flowers I place it 
in sect. Capreae. In Aitchison’s No. 574 the flowers and fruits are very similar to the 
type, but the young twigs and leaves are covered with a somewhat yellowish to- 
mentum. The old leaves are shining green above, only puberulous on the midribs, 
and glaucous beneath with only scattered hairs; they are ovate, somewhat acute 
at the base and apex, and entire or somewhat crenulate-dentate. They measure 
up to 10 em. in length and 4.2 cm. in width; the petioles are about 1 cm. long; 
the beg catkins are 7 cm. long and 1.2 em. thick. The old branches become 
purplish.
