H ab. Throughout Canada (Mrs Sheppard, Cleghom), from Lake Huron (Dr Todd) to the Saskatchawan
and Jasper's Lake in the Rooky Mountains (Drummond), and to the Columbia River (Douglas,
Scolder, Dr Gardner), and as far north as Fort Franklin on the Mackenzie River. Dr Richardson.— This
is perhaps one of the most generally diffused of all the Willows in British N. America, and is nearly allied
to our European S. pentandra.

H a b . Canada. About Quebec. Mrs Sheppard.—The long, falcate leaves, and large, broadly lunate,
reflexed stipules, readily distinguish this species. I am not acquainted with the male catkins.

H a b . Moist woods and prairies of the Saskatchawan. Prummond.—A Lake Winipeg and the Saskatchawan.
P r Richardson.—y. Great Slave Lake and the Mackenzie River. P r Richardson.—So variable
are the leaves of this plant in point of size, shape, and texture, that all kinds may be seen between lanceolate
and almost exactly cordate. It is only fair to observe, that Dr Barratt is disposed to consider the A and y.
good species ; but I really do not possess sufficient materials to give satisfactory characters. The branches
vary from bright yellow to deep brown.—Another state probably of this plant is found by Mr Douglas on
the Columbia River with quite entire leaves.
