DIOECIA— DIANDRIA. Salix. 197 



somewhat silky at the back. They are ovate and short j erect, 

 but hardly rising above the floral-leaves, very dense, with brown, 

 oblong, notched scales, clothed with copious, long, silky hairs. 

 Nect. an oblong, tumid, notched gland. Stam. not observed. 

 Germ, on a longish smooth stalk, elevated somewhat above the 

 scale, ovate, densely downy. Style scarcely any. Stigmas 

 ovate, obtuse, yellow, large and thick, at an advanced period 

 perhaps divided. 



The short ovate catkins, in which the present Salix differs from all 

 we have hitherto described, and agrees with a few other dwarf 

 species, particularly the rosmarinifoUa and Arbuscula, as soon 

 as they appeared in Mr. Crowe's garden proved this to be dis- 

 tinct from S.myrtilloides, for which it had previously been taken. 

 No Willow is more decidedly smooth in every part but what be- 

 longs to the fructification ; nor is the shape or proportion of the 

 leaves liable to variation. Its name commemorates that great 

 British botanist, who discovered it among his own native hills, 

 and who has gathered and discriminated more species perhaps 

 of this genus than any other person. His discoveries are every 

 day confirmed, as well as his remarks, 



The germens of the real .S. mijrtilloides, not yet found in Britain, 

 are quite smooth, in lax cylindrical catkins, and the leaves per- 

 fectly entire. Willdenow has mistaken smooth for downy in my 

 description of the leaves of S. Dicksonianu.

Shrub. April. 



Larger and more erect than S prunifolia or venulosa, to both which 

 it is nearly related in the fertile catkins. These are cylindrical, 

 slender, erect, twice the length of the sWky -hacked Jioral-leaves, 

 and quite unlike the short, dense, ovate catkins of the last-de- 

 scribed species. Their scales are rounded, concave, abrupt, half 

 as long as the germen, and clothed at the outside with long hairs. 

 Germen sessile, ovate, densely silky. Style smooth, very short. 

 Stigvias ovate, short and thick, finally notched. The branches 

 are elongated, brown, very slightly hairy when young. Leaves 

 elliptic-ovate, near an inch and half long, dark green, minutely 

 and copiously toothed, acute, smooth on both sides, except in 

 the bud, where they are externally silky. They are very re- 

 markably recurved, keeled, and folded, so that, having a con-
