? 't ? a ?j» 166. S. alpi'na ?Forbes. The alpine Willcfw.

Identification . ? Forbes Sal. Wob., No, 149. Mr. Forbes has not quoted an authority for the name,though he has noted that he was indebted to Professor Don for a specimen.

Engravings. Sal. Wob., No. 149. ; and our fig. 149. in p. 1630.

Spec. Char.,fyc. Leaves obovate, elliptic, entire; margins slightly revolute, densely silky on theupper surface; glaucous, reticulated, hairy underneath. Branches slender, and very black whendried. (Sal. Wob.,p. 279.) “ Dr. Graham kindly sent me living cuttings of a willow with thisname, alpina, from the Edinburgh Garden, in 1831; but I have not succeeded in cultivating it. Ithink it much resembled S. cordifblia Pursh , which I formerly had growing.

(Smith in Rees's Cyclo.) A native of Daiiria, in rocky places on the loftiest moun-tains ; growing, along with Rhododendron chrysanthum, near the limits of per-petual snow. The stems are branched and diffuse. Leaves with disks not muchabove § in. long, and so deeply toothed as to be almost pinnatifid; and veryhappily compared to those of the berberry. (Smith.) A variety with elongatedleaves is found in Kamtschatka. Introduced in ?1824, and flowering in May.

Identification. Roxb. Corom., 1. p. 66.]; Willd. Sp. PI., 4. p. 657.; Smith in’. Rees’s Cyclo., No. 9.;Forbes in Sal. Wob., No. 31.

The Sexes. Both sexes are figured in Rox.'Cor. and in Sal. Wob.

Spec. Char.,$c. Leaf oblong-lanceolate, with the upper part acuminate; serrated, glabrous, glau-cous beneath. Flowers blossoming after the protrusion of the] leaves. Male flower having 6 sta-mens. Ovary ovate, stalked. Style short. Wild in mountainous places in India, by the banksof rivers. (Willd. Sp. PI.) A native of India. Introduced in 1796, or soon afterwards. In itsnative country, it forms a middling-sized tree, with an erect trunk, but short, and as thick as aman’s body, bearing a very large branching head, with twiggy branches. It had not flowered inthe Woburn collection anteriorly to the date of the publication of that work in 1829.

tf 169. S. Plmifo'lia Forbes. The Elm-leaved Willow, or Sallow.

Identification. Forbes in Sal.Wob., No. 158.

The Sexes. The female is described in Sal. Wob., and in the Specific Character.

Spec. Char., %c. Stem erect. Leaves ovate-elliptic, serrated ; glaucous beneath, shining above; alittle heart-shaped and unequal at the base, acute at the tip. Stipules large, half-heart-shaped,serrated and glandular towards the stem. Ovary nearly sessile, ovate-lanceolate, glabrous. Style

• elongated, glabrous. Stigmas notched. Bracteas obovate, dark in their upper half, and fringed.(Sal. Wob., p. 286.) A native of Switzerland. Introduced in 1821, and flowering, in the Woburnsalictum, in April, and again in August. An upright bushy tree, attaining the height of 18 ft. ormore. Branches round, pubescent, of a dark brown colour, and marked with many small redspot9 towards autumn. The leaves from 2 in. to 2£ in. long, and 1$ in. ifi breadth, of an ovate-ellipticshape, sometimes hollowed out at the base; finely serrated; green and shining above, glaucousand besprinkled with minute hairs underneath. Footstalks above J in. long, villous, like the mid-rib. Catkin slender, 1| in. long when at maturity. Three applications of the epithet idmifblia,besides the above, have been made; namely, S. «lmifblia Tkuill. Paris., 518., Be Cand. Ft. Fr.

. 5. p. 340. ( Koch Comm., p. 37.; Smith Eng. FI .); S. wlmifblia Schl. (Steud. Norn. Pot.); and Swlmifblia Hort. Berol. (Koch Comm., p. 42.) Koch has referred the first of these to S. c&prea, andSmith to S. aurlta ; the second is referred, in Steud. Norn. Bot., to S. nigricans Smith ; the third by

; Koch, to his S. phylicifblia. ? Is Mr. Forbes’s distinct from all these. S. wlmifblia Thuill. is regis-tered in Hort. Brit., No. 24006., as having been introduced from Switzerland in 1821.

j* 170. S. villo'sa Forbes. The villous -leaved Willow.

Identification. Forbes in Sal. Wob., p. 183.

The Sexes. The plant in the Woburn collection had not flowered in 1829.

Engravings, Sal. Wob., t. 92.; and fig. 92. in p. 1619.

Spec. Char., &c. Leaves obovate-lanceolate, finely serrated towards the tip ; rather slightly toothed,and tapering towards the base; upper surface shining, and minutely covered with small hairs; be-neath glaucous, reticulated, and slightly hairy. (Sal. Wob., p. 183.) A small shrub, with slender,greenish yellow, villous branches, which are sometimes marked with yellow dots ; growing here tothe height of 2 ft. The leaves are from 1 in. to 1£ in. long, obovate-lanceolate, tapering towards the

■ base, minutely serrated at their tip, but generally finely toothed in the middle : often appearing asentire; their upper surface shining, besprinkled with very minute hairs ; under glaucous, reticu-lated, covered with small shining hairs. The whole substance of the leaves is very thin and tender.Mr. Forbes cannot unite this with the hitherto described species ; the leaves and slender growthof the branches being very different from any other species of the genus. It appears rather impa-tientofcold; and, as it suffers during the winter, that maybe one reason why it has not yetflowered A S. villbsa Schleicher is registered in Steudel’s Nomenclator Bolanicus ; and such islikely to be indigenous to Schlqicher’s country of residence, Switzerland, whether the kind noticedabove is identical with it, or not.
