T V e have this from Mr. G. Anderson under the above name,
flowering in April. Mr. W . Borrer gathered the same on the
rocks of Craig Challoch and Mael Ghyrdy in the Highlands.
It is doubtless very distinct from all we have hitherto published,
but we have no means of being certain that it is not included
under some name in Willdenow’s Sp. PI. having had only an
occasional inspection of the volume containing his Salices.
S. rupestris is a trailing or depressed shrub; the branches
very finely downy, of.a dark hue. Leaves about an inch long,
obovate, acute, broadish, even and flat, not wrinkled, finely and
regularly serrated, veiny, silky on both sides. The scales or
small leaves of the flowering buds are very smooth above. Stipulas
small, ovate, hairy. Catkins ovate and thick, their scales
very h airy; the female ones soon elongated and cylindrical.
The germen, which is stalked, hairy, and at first rather ovate,*
becomes lengthened and awlshaped. Style prominent, smooth.
Stigmas ovate, scarcely notched, never deeply cloven.
