H a b . Near the summits of the peaks in the Rocky Mountains— A small plant, intermediate, as it were,
between S. reticulata and S. herbacea, yet very distinct from both, especially in the very few-flowered
amenta, the larger, paler coloured, and veined scale, and the evident, though short, style. Leaves small,
quite entire.

£ to 2 inches. These leaves are generally beautifully silky beneath.

H ab. Labrador. Kohlmeister. Dr Morrison. High parts of the Rocky Mountains. Drummond.—The
plant thus named for me by Mr Borrer, who is probably acquainted with the original plant cultivated by Mr
Anderson, little deserves the appellation of cordifolia, its leaves being more frequently acute than retuse at
the base. Many of the specimens approach very near to the following.

Hab. Throughout the barren country of N. America, from lat. 64° to the shores and extreme islands of
the Arctic Sea. Captain Bass. D r Richardson.'brador. Miss Brenton.—This plant has a dispositi onS itro Etu.r nP aalrmryo,s t& bc.l ack in drying, and the catkins hav-e a
peculiarly dingy or sooty hue, from the dark colour of the large scales and of the elongated styles and stigmas.

for me to venture to offer a character from them. Dr Richardson’s “ S. Ammanniana ?" appears to me to
be the same with this.

specimen was brought home).—A very distinct and beautiful species, with glossy, strongly nerved, perennial
leaves, the skeleton nerves remaining in the lower parts of the stem. Ovaries and fruit very large in proportion
to the size of the plant.

H ab . Unalaschka. Chamisso in Herb, nostr.—Chamisso doubts if this be the true S. polaris of
Wahlenberg, on account of the glabrous ovary. It does not seem to have been elsewhere found in Arctic
America; but I have specimens gathered by Sir Edward Parry’s officers in Spitzbergen.
(Many specimens of Salix yet remain in the British N. American Herbarium, in too imperfect a state to
be determined. Chamisso quotes the /S. arctica of Pallas (not Br.), a very dubious species it must be confessed,
as a native of Unalaschka, and S. glauca, L. and Koch. (S. sm'cea, Vill. and Ser.), of Chamisso’s
Island and Cape Espenberg, in Behring’s Straits. Bongard, in his “ Veget. de Sitcha,” gives the following
brief character of “ S. Sitchensis,” Sanson, mst.:—“ amentis fructiferis breviter peduneulatis, pedunculo
subfoliato; capsulis ovato-lanceolatis tomentosis pedicellatis, pedicello nectarium 2-3-superante, stylo elongato,
stigmatibus bifidis (?); foliis oblongo-obovatis obsolete crenulatis, supra pubescentibus, subtus cano-tomen-
tosis.”—A single specimen, with foliage only, which M. Bongard has kindly communicated to me, does not
enable me to refer it to any previously described species).
