that of the Faccinium ^fyrsinites; and it may be supposed that this cha- 

 racter obtains more or less in all the kinds of the group. 



-t* 153. S. .MYRSINI'TES L. The Whortleberry -leaved Willow.

JSpec. Char., $c. This has, like S. fctulifolia, short catkins, and 

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

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

 tinctive character. (Borrer in Eng. Bot. Suppl., t. 2753., in the 

 text.) It occurs on various Scottish mountains. (Id.) Wahlenberg 

 compares the stems and leaves to those of 2?etula nana, from the 

 glossy greenness of the latter, their prominent veins, and their 

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

 The whole plant is very dark, and almost black when dry. (Hook. 1344 

 Br. Fl.) 



jk 154. S. .SETULIFO'LIA Forster. The dwarf Birch-leaved Willow. 



Identification. Forster MS., cited by Borrer in Eng. Bot. Suppl., t 2753., in the text. 



Synonymes. S. 3/yrsinltes Smith Eng. Sot., 1. 1360., exclusively of the references to HoffYnann (Smith 



in Eng. FL), Eng. Fl., 4. p. 195., exclusively of the var. /3, Forbes in Sal. Wob., No. 60., Hook. 



Br. FL, ed. 2., p. 429., exclusively of the var. /3, not of Linn. (Borrer) ; S. jl/yrsinltes Koch, part 



of, Koch Comm., p. 60. 



The Sexes. The female is described in Eng. Fl., and figured in Eng. Bot. and Sal. Wob. 

 Engravings. Eng. Bot., 1. 1360. : Smith in Eng. Fl. has quoted, besides, Lin. FL Lapp., t. 7. f. 6. t. 8. 



f. / ; and Villars Dauph., 3. t50. f. 12. : but has designated this as "bad : " Sal. Wob., No. 60. ; 



our fig. 1345. ; and fig. 60. in p. 1615. 



Spec. Char., $c. It differs from S. procumbens 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 primd facie resemblance of its leaves 

 to those of 2?etula 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. -Myrsinites of Eng. 

 Bot., or with S. procumbens Eng. Bot, Suppl., he has stated 1345 

 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 Abbey, it has flowered in May, and again in 

 August. A sturdy, upright, bushy shrub, 1 ft. 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 S. 

 walifdlia, 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 Eng. Fl.) Pursh has included in his Flor. 

 Amer. Sept., ii. p. 617., a North American kind of willow, named S. Myr- 

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



Jc 155. S. PROCU'MBENS Forbes. The procumbent Willow. 



Identification. Forbes in Sal. Wob., No. 61., exclusively of the synonymes. The figure is not a cha- 

 racteristic one. (Borrer in Eng. Bot. Suppl., t. 2753.) Hook. Br. Fl., ed. 2., p. 429. ; Borrer in Eng. 

 BoL Suppl., t 2753. 



Synonymet. S. la'vis Hook. Br. Fl., ed. 1., p. 432. ; S. retDsa Wither. Sot. Arr., ed. 4., 2. p. 49., and

has not come under our notice. (Borrer.) 

 Engravings. Wither. Bot. Arr., ed, 4., vol.2. ; Sal. Wob., No. 61., the figure not a characteristic
