174 DIOECIA— DIANDRIA. Salix. 



oblong stigmas, and subsequently longer. Barren catkins not 

 observed. 



Wahlenberg declares that the figure in Engl. Bot. agrees suffici- 

 ently well with his S. phylicifoUa, but that in this latter the 

 germens are much more elongated, (which his plate expresses,) 

 and by no means silky ; though the young branches are always 

 downy, like the footstalks, and common stalk of each catkin. 

 The last character only answers to our Scottish plant, whose 

 young branches and footstalks are very smooth, while the ger- 

 mens, scales and common stalk are silky. This author therefore 

 must mean a distinct species from our's. The specimens of 

 Lightfoot and Linnaeus precisely agree in leaves, but both are 

 destitute of fructification ; so that the points in dispute, cannot 

 by them be absolutely settled, except that their branches and 

 footstalks are smooth. 



Fl. Dan. t. 1052 bears scarcely any resemblance to the species 

 before usj and t. 10.53 is quite different from S. nigricans. S. 

 Croweana is as unlike phyUcifolia. 



8. S. jBorreria?ia. Dark Upright Willow. 



Leaves lanceolate, with shallow even serratures, very 

 smooth ; glaucous beneath. Stipulas obsolete. Branches 

 upi'ight. Scales of the catkins acute, shaggy.

Shrub. May. 



A bushy shrub, 8 or 10 feet high, with copious, dark-brown or 

 blackish, short branches, quite smooth in every stage of growth, 

 and always erect, by no means spreading or trailing. Leaves 

 perfectly lanceolate, with smaller, more even serratures than the 

 last, dark- green, quite smooth at every period, and about 2 

 inches long ; their under surface very glaucous, or blueish. 

 Footstalks longer, and more slender, than the foregoing. Sti' 

 pulas scarcely ever visible, but, if present, very small and lan- 

 ceolate. Barren catkins, the only ones I have seen, copious, 

 lateral, on short stalks, coming before the leaves ; their scales 

 ovate, acute, brown, densely shaggy with long silvery hairs, 

 quite unlike the silky down of S. phyUcifolia. Filam. 2, bright 

 yellow, smooth, long and slender. Anth. oblong, of a deeper 

 hue. 



Fl.Dan. t. 1052, which has no stipulas, and which the author re- 

 fers, with doubt, to n. 350 of Linn. Fl.Lapp. t.8.f. c, (that is 

 S. nigricans,) comes nearer to phyUcifolia ; but answers better, 

 except the broad-leaved shoot in the plate, to S. Borreriana, 

 whose upright, bushy branches it well expresses. The catkins 

 indeed are drawn much smaller, and their scalesiax less shaggy.
