Spec. Cluir., Sfc. This has, like S. ictulifolia, short catkins, and 

 distinctly serrated leaves ; but these are more acute, and of an 

 ovate-lanceolate figure; and the long style seems to aflbrd a dis- 

 tinctive character. (Burnr in Etig. But. Sup/)/., t. 27 o'-i., in the 

 text.) It occurs cm various Scottish mountains. (/(/.) Wahlenberg '^\i| 

 compares the stems and leaves to those of i/etula nana, from the .'.^^k| 

 glos.sy greenness of the latter, their prominent veins, and their -^ " 

 remaining on the shoots in a withered state till the following year. 

 The whole jdant is very dark, and almost black when dry. (//oo/i. 13+4

Spec. Chnr., Sfc. It differs from S. proeumbens by its smaller, rounder, more 

 conspicuously serrated leaves ; shorter, almost ovate, catkins ; shorter, 

 more truncate, and paler bracteas (scales) ; and more distinctly quadrangular 

 ovary. From the remarkable prima facie resemblance of its leaves 

 to those of jBetula nana, Mr. Forster has suggested for it the 

 name of ietulifolia. (Borrer in Eng. Bot. Suppl.) Mr. Borrer 

 regards it as not certain that this kind is a native of Britain ; and 

 the question resting on whether the kind found by Dr. Stuart in 

 the mountains of Glencoe is identical with S. il/yrsinites of Eng. 

 Bot., or with S. proeumbens Eng. Bot. Suppl., he has stated 

 that, to ascertain this, it would be necessary to inspect the specimens of 

 the kind found by Stuart, preserved in Lightfoot's herbarium. If the kind 

 prove not British, Mr. Borrer does not know its source. Cultivated in 

 the willow garden at Woburn Abiiey, it has flowered in May, and again in 

 August. A sturdy, upright, bushy shrub, 1ft. to 2 ft. high, with abun- 

 dance of short, leafy, dark purplish branches, hairy when young, not downy. 

 Leaves very different from those of all the foregoing species, except ^V. 

 ;);alifolia, in their rigid, thin, crackling, veiny texture; without anything 

 glaucous or cottony about them, the fine hairs on the younger ones being 

 scattered and silky. (Smith E7ig. Fl.) Pursh "has included in his Flor. 

 Amcr. Sept., ii. p. G17., a North American kind of willow, named S. il/yr- 

 sinites : ? is this the same as either of the above.
