Spec. Char., Src. Leaves elliptic-lanceolate, nearly entire; villous above, whiteand cottony beneath. Stipules not apparent. Catkins nearly 1 in. long.Bractea reddish. Anthers yellow. (Sal. Wob., p. 185.) A native of Switzer-land. Introduced in 1820, and flowering in April and May. A low uprightshrub, with round, yellowish, pubescent, slender branches, which soon turnblack in drying, the old ones becoming glabrous and brown. Leaves from2 in. to 2J in. in length ; elliptic-lanceolate, bright green, wrinkled, andpubescent; beneath, somewhat glaucous, whitish, densely pubescent, reticu-lated with prominent arched veins, their margins slightly revolute ; at firstseeming entire, but, on minute investigation, appearing furnished with a fewdistant glandular serratures towards the apex. Barren catkins from £ in.to 1 in. long. Anthers yellow. The twigs are brittle, and, though ratherelongated, Mr. Forbes thinks them unfit for basketwork. Mr. Borrerremarks of this kind, that, perhaps, it is not of the group Viminales, inwhich he has placed it. According to a specimen of it which has been sentto us by Mr. Brooks of Flitwick House, it has rounded rather tumid buds,and the shoot is rather angled ; and in these characters, and in those of its
