 /. c. «. 350. 



In falicetis Fl. Aprili. 



At Wrongay fen, Norfolk, and in ofier grounds in other places 

 not uncommon. Mr. Crowe. 



No writer except Linnaeus appear to have known Willow, this 

 but he furely has erred in making it a variety of his phylicifolia, from 

 which it differs in the much greater fize of all its parts, as well as in 

 the totally different form of its ferratures, a part fo peculiarly cha- 

 ra£teriftic in \\\g phylicifolia. 



This fpecies I have named nigricans from the dark colour of its 

 branches, as well as its black hue when dried, which laft indeed is 

 not abfolutely pecuUar to it. The trunk fcarcely rifes to the height 

 or form of a tree. The branches are upright, round, rather brittle, 

 fmooth. Leaves 2 or 3 inches long, elliptic-lanceolate, acute, a 

 little rounded at the bafe, crenate in almoft every part, but more 

 flightly in the female plant; dark-green and very fmooth above ; 

 glaucous, veiny, rarely a little hairy beneath. Foot-ftalks verv 

 broad at their bafe. Stipulse (if prefent) rather large, obliquely 

 heart-lhaped, ferrated, fmooth. Catkins from an inch to an inch 

 and half long, thickifli, with, obovate, brown, hairy fcales. Stamina 

 2, diftind, more or lefs hairy about their bafe. Style fliort, fmooth. 

 Stigmas thick, ovate, united at their bafe, permanent, undivided. 

 Capfules on footftalks, long and tapering, clothed with white filky 

 down, as are the general and partial ftalks. 



The leaves in the female plant are fhorter, and lefs crenate, as 



well as more tapering towards the bafe. Such differences between 



the two fexes of Willows arc rare, but I can hardly conceive thcfe 



to be different fpecies, as they agree in every part befuics.
