DIOFXIA— DIANDRIA. Salix. 177 



In Breadalbanc ; also by the river side near the bridge at Kirby 

 Lonsdale. Mr. W. Borrer. 



Shrub. April, May. 



Stem branched^ at first diffuse, 12 or 18 inches high ; afterwards 

 upright, attaining the height of a man ; branches straggling, 

 short, scarcely downy, except partially when young. Leaves 

 an inch or inch and half long, broadly obovate at an early period, 

 afterwards more elliptical, with a small point ; smooth all over, 

 except at an early age, when the upper surface and its midrib, 

 as well as the footstalks above, are now and then finely downyj 

 the under side is glaucous and always smooth, like the back of 

 the footstalks ; veins reticulated at right angles, as in the last; 

 serratures shallow. Stipulas very minute in our specimens, and 

 scarcely discernible in Wulfen's, communicated by Jacquin ; 

 but they are said to appear on the oldest branches, of an ovate, 

 <:cute shape, or clasping the branch in a semicircular form. 

 Catkins accompanying the young leaves, each on a short, la- 

 teral, downy, almost leafless, stalk ; the barren ones an inch 

 long ; fertile when in fruit twice as large. Scales oblong, more 

 or less hairy, always fringed. Stamens thrice their length, as is 

 likewise the awl-shaped, mostly smooth, germen, whose densely 

 hairy stalk is only about half as long as the annexed scale. 

 Caps, smooth, tumid at the base, awl-shaped above. Style and 

 stigmas permanent, smooth ; the latter deeply cloven, about 

 half the length of the style, 



12. S. tetrapla. Four-ranked Willow. 



Leaves elliptic-oblong, pointed, unequally serrated, nearly 

 smooth; glaucous, with prominent veins, beneath. Sti- 

 pulas half-heartshaped. Scales mostly shorter than the 

 hairy stalks of the ovate-oblong smooth germens. Style 

 as long as the stigmas. 



S. tetrapla. Walk. Ess. 408 j according to Mr. G. Anderson, 



In the Highlands of Scotland. 



Gathered in Breadalbane, by Mr. IV. Borrer. 



Shrub. May. 



Nearly related to the last, from which I Will not assert it to be 

 specifically distinct. Yet having long been known by the name 

 of tetrapla, which originated with the late Rev. Dr. Walker, I 

 think it worth noting, for future examination. This name 

 alludes to the spiral insertion of the leaves, of which, according 

 to the learned writer, four complete each circuit of the branch. 

 The whole shrub is larger than S. JVulfeniana ,- the leaves longer, 

 more elliptical, and more pointed, with unequal, coarse and 

 wavy serratures ; deep green above ; finely glaucous, with pro- 

 minent, pale or reddish^ veins beneath ; smooth, except a very
