Hab. N. W. America. Vallies of the Rocky Mountains. M. Lewis. Between the Mountains and the
Pacific, from the parallel of 38° to 50° N.—This is assuredly a very distinct plant, both as to genus as well
as species, from the Silla esculenta, Fraser, with which Pursh (in Bot. Mag. t. 1574) and Mr Nuttall con-
ounded it, and led others to do so too. Both are eaten in their respective countries by the Indians, the present
one by the Chenooks, who toast the roots on heated stones, and, when dried or compressed into cakes,
they form a great article of consumption during the winter months.

of Mr Bentham, in Hort. Trans, v. 1. N. S. t. 15. ƒ. 2, and Lindl. Bot. Beg. t. 1685, (both of which
figures accurately represent ours, the original species of the genus,) can be distinguished from the present.
It is a beautiful plant, with the habit of the following genus.

species from B. grandiflora, the. only ones found in N. W. America.

have the preference.
