21. S. tenuifolia (thin-leaved Willow], " leaves elliptical acute 

 serrated srnoothish glaucous beneath, stipules obsolete, cap- 

 sules very smooth," Sm. E. B. t. 21 86. 



HAB. Drawn in E. B. from the garden of Mr. T. Forster, who receiv- 

 ed it from Scotland. Various parts of Scotland, D.Don. Ft. May, 

 June, fy . 



This species I never saw. There are no germens figured in E. B. 



22. S. myrsmites (green Whor tie -leaved Willow), leaves oval 

 serrated veined shining quite glabrous, germens nearly sessile 

 lanceolate slightly downy, style elongated, stigmas bifid. E.B. 

 t. 1360. 



HAB. Mountains of Glen-co, Dr. Stuart. Fl. June. T? . 



A low,, shining, bushy shrub, with thick, much branching stems and 

 roundish-oval leaves, not unlike some Vaccin'mm, or more like, 

 both in habit and dark colour, as Wahlenberg well observes, Be- 

 tula nana. Leaves rigid, often keeled at the back, much veined. The 

 jlowers appear when the plant is in full leaf. Scales small, blackish, 

 with silky long hairs. 



23. S. pruni/olia (Plum-leaved Willow), leaves ovate serrated 

 more or less veiny glabrous glaucous beneath, germens sessile 

 oblongo- ovate extremely silky, style short, stigmas notched. 

 Ligktf.p.599 (S. myrsinites), according to Smith. E. B. 

 t. J361, and t. 1362 (S. vtnulosa.). 



/3. leaves ovato-oblong. S. vacciniijolia, E. B. t. 2341. 



HAB. Breadalbane mountains, Dr. Stuart. Blair, in Athol, Mr. 

 M'Nab. Marsh south from Huggenfield Loch, rare (?), Hopk. 

 B. South of Scotland. FL April, May. J? . 



Leaves ovate, not shining like the last, and paler green. The Jlowers 

 appear before the expansion of the leaves. Germens smaller, much 

 more silky, and the scales longer and extremely silky j forming a 

 very compact, cylindrical, obtuse catkin. I can see no difference 

 whatever in the S.vacciniifoUa,but in the leaves being narrower j they 

 are silky beneath only in a young state. I think the veiny leaves 

 of the S. venulosa cannot constitute a species j besides which the 

 veins are more or less apparent on different individuals : and in the 

 specimens I have from Sir James Smith there is no other character 

 whatever. 



24. S. carinata (folded-leaved Willow\ leaves ovate serrated 

 glabrous glaucous beneath frequently folded so as to form a 

 keel, germens sessile oblongo-ovate extremely silky, style 

 short, stigmas notched. E. B. t. 1363. 



Plant 2 feet high. Leaves generally longer than the last, and mostly 

 remarkably carinated by the laterally folding together of the two 

 halves ; but I see no other difference. 



25. S. Dicksoniana (broad- leaved Mountain Willow}, "leaves 

 elliptical acute slightly toothed glabrous glaucous beneath, 

 young branches very glabrous, catkins ovate short erect silky," 

 Sm. E. B. t. 1390.
