DIOECIA— DIANDRIA. Salix. 177 



In Breadcilbanej also by the river side near the bridge at Kirby 

 Lonsdale. Mr. M\ Borrer. 



Shrub. April, May. 



Stem branched, at first diffuse, I '2 or 18 inches high: afterwards 

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

 short, scarcely downy, exce))t 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 downy ; 

 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 j 

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

 acute 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. Stijle and 

 stigmas permanent, smooth • the latter deeply cloven, about 

 half the length of the style. 



12. S. tetrapla. Four- ranked Willow. 



Leaves elliptic-obloiio', pointed, unequally .serrated, nearly 

 smootli ; <rhiucous, with prominent veins, beneath. Sti- 

 }nilas lialf-hearisliaped. Scales mostly shorter than the 

 hairy stalks of the ovate-oblong smooth germens. Style 

 as lono; as the sti^jmas. 



S. tetrapla. Walk. Ess. 408 ^ according to Mr. Ci. Anderson. 



In the Iligldands of Scotland.

Nearly related to the last, from wliich 1 will not assert it to he 

 specifically distinct. Vet having long been known by the name 

 of tetrapl'iy which originated witii 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 shrnh is larger than N. fl'itffeniana ; the leaves longer, 

 more ellij)tical, and more pointed, with unequal, coarse and 

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

 minent, pale or reddish, veins beneath j smooth, except a very
