?Y ?dfc ?m 166. & aliVna f Forbes. The alpine Willow. 



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 revolutc, densely silky on the 

 upper surface; glaucous, reticulated, hairy underneath. Branches slender, and very black when 

 dried. [Sal. lVob.,\i. 279.) " Dr. Graham kindly sent me living cuttings of a willow with this 

 name, alplna, from the Edinburgh Garden, in 1831 ; but I have not succeeded in cultivating it. I 

 think it much resembled S. cordifftlia Pursh, which I formerly had growing.

 Sib., 1. t. 35. f. 3. ; Sal. Wob., No. 140. ; our fig. 1355. ; and fig. 140. in p. 1630. 



Spec. Char., H(c. Leaves obovate, bluntish, with deep tooth-like serratures, glabrous, 

 shining, ribbed, and reticulated with veins on both sides. Capsules ovate, glabrous. 

 (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 much 

 above f in. long, and so deeply toothed as to be almost pinnatifid ; and very 

 happily compared to those of the berberry. (Smith.) A variety with elongated 1S55 



leaves is found in Kamtschatka. Introduced in ?1824, and flowering in May. 



¥ 168. S. tetraspe'rma Roxb. The four-seeded Willow. 



Identification. Roxb. Corom., 1. p. 66..; Willd. Sp. PL, 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. 



Engravings. Roxb. Corom., 1. 1. 97. ; Sal. Wob., No. 31. ; and fig. 31. in p. 1609. 



Spec. Char., S(c. Leaf oblong-lanceolate, with the upper part acuminate ; serrated, glabrous, glau- 

 cous beneath. Flowers blossoming after the protrusion of thej leaves. Male flower having 6 sta- 

 mens. Ovary ovate, stalked. Style short. Wild in mountainous places in India, by the banks 

 of rivers. (Willd. Sp. PI.) A native of India. Introduced in 1796, or soon afterwards. In its 

 native country, it forms a middling-sized tree, with an erect trunk, but short, and as thick as a 

 man's body, bearing a very large branching head, with twiggy branches. It had not flowered in 

 the Woburn collection anteriorly to the date of the publication of that work in 1829. 



1 169. S. llmifo^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., S(C. Stem erect. Leaves ovate-elliptic, serrated ; glaucous beneath, shining above : a 

 little 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 Woburn 

 salictum, in April, and again in August. An upright bushy tree, attaining the height of 18 ft. or 

 more. Branches round, pubescent, of a dark brown colour, and marked with many small red 

 spots towards autumn. The leaves from 2 in. to 2| in. long, and If in. in breadth, of an ovate-elliptic 

 shape, sometimes hollowed out at the base ; finely serrated ; green and shining above, glaucous 

 and besprinkled with minute hairs underneath. Footstalks above fin. long, villous, like the mid- 

 rib. Catkin slender, If in. long when at maturity. Three applications of the epithet wlmifdlia, 

 besides the above, have been made; namely, S. wlmifblia Thuill. Paris., 518., Be Cand. Fl. Fr. 

 5. p. 340. (Koch Comm., p. 37.; Smith Eng. Fl.) ; S. wlmifblia Schl. (Steud. Norn. Rot.) ; and S 

 wlmifolia Hort. Berol. (Koch Comm., p. 42.) Koch has referred the first of these to S. caprea, and 

 Smith to S. aurlta ; the second is referred, in Steud. Nom. Rot., to S. nigricans Smith ; the third by 



t Koch, to his S. phylicifblia. ? Is Mr. Forbes's distinct from all these. S. wlmifolia Thuill. is regis- 

 tered in Hort. Brit., No. 24006., as having been introduced from Switzerland in 1821. 



j* 170. S. villoma Forbes. The viilous-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. ; andfig. 92. in p. 1619. 



Spec. Char., S(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 to 

 the height of 2 ft. The leaves are from 1 in. to If in. long, obovate-lanceolate, tapering towards the 

 base, minutely serrated at their tip, but generally finely toothed in the middle : often appearing as 

 entire; 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 growth 

 of the branches being very different from any other species of the genus. It appears rather impa- 

 tient of cold; and, as it suffers during the winter, that may be .one reason why it has not yet 

 flowered A S. villosa Schleicher is registered in Steudcl's Nomenclator Botanicus ; and such is 

 likely to be indigenous to Schleicher's country of residence, Switzerland, whether the kind noticed 

 above is identical with it, or not.
