Shrub. May. 



Stem 2 or 3 feet high, stout, bushy, with numerous short, round, 

 spreading, brown or yellowish branches, downy in their early 

 state. Leaves near 2 inches long, and half, or three quarters, of an 

 inch wide, elliptic-lanceolate, acute, often broadest rather above 

 the middle, somewhat rounded at the base, nearly, if not in every 

 part, quite entire; the upper side of a beautiful glaucous green, 

 remarkably even, perfectly smooth when full grown ; under 

 densely downy, or cottony, of no less elegant and pure a white, 

 with slightly prominent veins, and a reddish midrib. Stipulas 

 small, convex, ovate, or rounded, as represented in Fl. Dan. but 

 often wanting. Footstalks rather stout, reddish, a little downy ; 

 their base dilated and keeled, meeting a similar projection of 

 the branch at their insertion, as in S. lanceolata, n. 3. Buds 

 elliptical, brown, downy, rather large. Catkins solitary, on 

 short, lateral, downy branches, with 2 elliptical, stalked, /oraZ- 

 leaves, which are ve'ry silky at the back, and become near an 

 inch long by the time the seeds are ripe ; erect, cylindrical, 

 stout, dense', many-flowered. Scales ovate, blackish, densely 

 hairy. Nect. a solitary oblong gland. Stamens 2, capillary, 

 yellow, many times longer than the scale. Germen at first ses- 

 sile, ovate, twice the length of the scale, thickly covered with 

 very white down, and afterwards becoming a tawny, less downy, 

 somewhat stalked, capsule. Style short in the flower, with thick 

 ovate stigmac ; much elongated as the fruit ripens, the stigmas 

 linear and deeply cloven. 

 Haller's plate well represents this handsome species, insomuch 

 that one cannot but wonder at its having been enveloped in any 

 obscurity. Authentic Swiss specimens answer precisely to those 

 of Linnaeus, and the plant remains unchanged by many years' 

 culture. Wahlenberg unites it with S. lapponum, which I can- 

 not but think the arenaria of FL Dan. t. 197, whatever t, 1058 

 of the same work may be. S. sericea of Villars, according to his 

 own specimens, is the true lapponum, and I have Swiss ones, 

 properly so named, from M. Schleicher. It is Haller's n. 1643. 

 This species, as yet, has not been noticed in Britain. The leaves 

 are 2 or 2h inches long, greyish, all over very silky, both sides 

 alike, at every period of their growth, and never cottony ; the 

 catkins large, with large Jl oral-leaves, like the proper foliage j 

 and oblong hairy scales ; tlic germens and rnpsvles sessile, pe-
