DIOECIA— DIANDRIA. Salix. 213 



German, and Linnaean specimens, however various in the size 

 and breadth of their foliage, agree with Mr. Forster's Hopton 

 plant, is the prominence of the transverse and marginal veins, 

 forming a strong network, on the naked upper surface of each 

 leaf. The common S. repens alone has nearly the same cha- 

 r^icter ; but the much greater size of the present plant, its long 

 spreading branches, and a total difference of habit, surely must 

 keep it distinct ; yet I have it from Germany as the repens of 

 Linnaeus, and depressa of Hoffmann. The ungustifoUa of Jac- 

 quin from himself, precisely what is represented in all the wood 

 cuts above cited, has longer narrower /eaues, and shorter catkins 

 when in seed ; yet I have various Swiss specimens connecting 

 this with our Norfolk plant, some of them altogether the same 

 as what Linnaeus has marked incubacea, though the latter speci- 

 men is not of Swedish growth. 

 Whatever this Salix may be, which I must at present be content 

 to add to our Flora, under Mr. Forster's sanction, as incuba- 

 cea ; it has nothing to do with my fcetida, prostrata, fusca, or 

 argentea.

Sent from Scotland, as British, by the late Mr. George Don, to 

 the late Mr. George Anderson. Mr. Borrer. 



Shrub. Ma7j. 



Stem 5 or 6 feet 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 are opposite, all nearly upright, flat, an inch 

 and quarter long, uniform ; broadest, and most evidently ser- 

 rated, in their upper part, towards the point ; green, minutely 

 veiny, and smooth, 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 evident on 

 the older ones. Footstalks stout, very broad at the base, paler 

 than the branches. Stipulas none. Catkins before the leaves, 

 numerous, scattered, on short lateral stalks, each accompanied 

 by 3 or 4 elliptic-oblong, partly silky, bracteas ; erect, cylindri- 

 cal, three quarters of an inch long, obtuse, dense, many-flowered. 

 Scales obovate, partly blackish, bearded, about half the length 

 of the germen with its stalk. Germ, ovate, covered, as well as 

 the stalk, with long silky hairs. Style short. Stigmas short
