tained examples of S. daphnoides, named upon good authority, both 
from Germany and Scandinavia; but I was unacquainted with 8. aeu- 
tifolia, except by descriptions. At first, from its somewhat hairy 
young leaves (the leaves and stipules being scarcely narrower than 
those of the Scandinavian daphnoides), I supposed that the Cleveland 
plaut might belong to a narrow-leaved form of that species. But 
upon sending it to Mr. Borrer and the Rev. J. E. Leefe, they both 
decided that it was S. acutifolia; the former kindly favouring me with 
a specimen showing that the young leaves of that species are also 
somewhat hairy ; and the latter taking the pains to ascertain its iden- 
tity with authenticated examples from Professor Koch. 
So that with a description of Salix acutifolia, as it occurs in Bri- 
tain, I will conclude. 
S. acutifolia, Willd.—A tall bush, or shrub, moderately branched ; 
inner bark lemon-coloured in the latter half of the year; branches 
long and wand-like, glossy, glabrous, dark purple, covered with a 
loose, easily disturbed coating of czsious bloom, especially when 
pressed ; stipules large, persistent, lanceolate-acuminate, glanduloso- 
serrate ; petioles glandular like those of the Pentandre ; leaf-buds 
somewhat downy and villose; leaves elongate-lanceolate, much acu- 
minated, dark green above, lighter and somewhat glaucous beneath, 
rigid in texture, very brittle when dry, prominently vemed, mode- 
rately glanduloso-crenate-serrate. Female flowers unknown. Male 
catkins lateral, subsessile, bracteated at the base, sparingly produced, 
oblong, rounded at the apex; scales shaggy; filaments two, free ; 
anthers yellow when matured, afterwards gray. Amongst British 
willows, most resembling the Purpurez in its habit of growth; the 
Fragiles, in the shape and serrature of its leaves; and Salix Lappo- 
num (S. arenaria, Auct. Brit.) or 8. lanata, in its female flowers ; but 
very unlikely to be mistaken for, or confounded with, any of them.
