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. manshurica Siuzev (in 

 Trav. Bot. Mtis. Acad. Sci. St. Petersbourg, 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 cf 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 9 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 cm. in length and 4.2 cm. in width; the petioles are about 1 cm. long; 

 the fruiting catkins are 7 cm. long and 1.2 cm. thick. The old branches become 

 purplish.
