F O R this new fpecies of Salix we are obliged to Mr. Dick-
fon, who found it in fome part of Great Britain, the exafit
place is not remembered, and fent it in a growing date to
Mr. Crowe. We only know the female, which is a fmall
fpreading tree, flowering in April. The branches are (lender,
flexible, round, fmooth, more or lefs purple or brown.
Leaves 4 or 5 inches long and almoft an inch broad when
full-grown, lanceolate, pointed, ferrated throughout, generally
unequal at their bafe; bright-green and fmooth above;
glaucous and often a little hairy beneath; in drying they turn
almoft black. Footftalks remarkably long and (lender.
Stipulse fmall, lunate, fmooth, toothed. Female catkins
fcarcely an inch long, on (talks. Scales fmall, obtufe, often
notched, black and hairy. Germen on a long (talk, ovate,
filky, with two feflile, ovate, blunt, cloven ftigmas. The
very young leaves are tinged with an elegant ferruginous hue,
efpecially in the radical (hoots which fpring up when a tree is
cut down. Such (hoots in fome fpecies differ greatly from the
general appearance of the plant, and require in this genus to
be particularly attended to. The ftigmas and germen are alio
of great moment in difcriminating many fpecies.
