Scotland. FL May. Tj . — Shrub 6 feet or more high, resembling S. 

 purpurea, but the sterile Jiuwers are unknown, and Mr Borrer considers 

 it correctly placed in the present division, on account of its stalked 

 germens which have little resemblance to those of the Monandrcc, but 

 are closely analogous with those of S.fusca, to which species he thinks 

 there is considerable afKnity in the foliage also.

Moist and dry heaths, moors and sandy situations. Fl. Apr. May. Tj . 

 — I am happy to learn, from Mr Borrer, that he not only consents to the 

 union of the above-mentioned species of other authors, but has suggested 

 the order of their arrangement; with the single exception of S. fusca 

 of Sm., which he is disposed to consider different from that of Linn., at 

 least as seen growing in the garden ; for he allows that " the dried spe- 

 cmiens show !io character ;" in which latter opinion I cordially agree 



with him The plant itself is usually a small ])rocumbent shrub, with 



rather long straight branches ; but varying exceedingly, according to 

 situation and otlier circumstances, as do the leaves also, which are more 

 or less glabrous above, and more or less silky beneath where the nerves 

 arc prominent. 



9. Ambiguse. Borr. 



'22. S. ambigua, Ehrh. (cimbiguous Willoio); leaves obovato- 



' The Ejjping- Forest ^' prostrata," mentioned in E. FL, is, on the authority 

 of Mr E. l-orster, one of the varieties of S. ambigua.
