PART J II. 



This species is readily distinguished from the remaining ones be- 

 longing to this section (with the exception of S, ineubacea), by its 

 \er\ silvery leaves and upright mode of growth. Both sexes are 

 described in Eng. Fl. ; the female is figured in Sal. Wob. and Hayne 



Abbild. There are plants at Wobnrn Abbey, Henfield, and Flitwick 

 House, ami also in the Goldworth Arboretum.

Spec. Char. i d}c, Leaves obovate-lanceolate, partly opposite, acute, slightly 

 serrated, even ; livid and somewhat silky beneath. Stipules linear. Branches 

 erect. Catkins erect, cylindrical. Ovary stalked, silky, longer than the 

 obovate bearded bractea. (Smith and Borrer.) Sent from 

 Scotland, as British, by the late Mr. George Don. It 

 flowers in May. Stem 5 ft. or 6 ft. high, with straight, 

 wand-like, round, leafy branches, of a reddish or rusty 

 brown, scarcely downy, except when very young. Leaves 

 mostly alternate, but several of the lowermost pairs oppo- 

 site ; all nearly upright, flat; l^in. long, uniform; broadest, 

 and most evidently serrated, in their upper part, towards 

 the point; green, minutely veiny, and glabrous above ; livid, 

 or in some measure glaucous, as well as finely downy or silky, beneath, 

 with a prominent reddish midrib, and slender veins ; the silkiness less evi- 

 dent on the older ones. Footstalks short, very broad at the base, paler 

 than the. branches. Catkins of female flowers appearing before the 

 leaves, on short lateral stalks. (Smith.) S. Doniana, in the female, which is 

 the only sex at present known to British botanists, assimilates to the kinds 

 of the group Purpureas, except S. rubra Uuds., in the aspect of the branches, 

 shoots, leaves, and catkins ; in some of the leaves being opposite ; and in 

 the old bark being internally yellow, though less remarkably so than that of 

 these kinds ; but it differs from them in having its leaves silky beneath, 

 and its ovary stalked, and Mr. Borrer believes that, in the relation of 

 affinity, it is nearest to S. fusca ; but he notices that we are without the 

 means of proof, which the male flowers would afford. There are plants 

 at Woburn Abbey, Henfield, and Flitwick House, and in the Goldworth 

 Arboretum.
