Hab. Common on dry rocky places of the Columbia and Salmon Rivers. Douglas.—The lower decumbent
part of the stem sends forth fibrous roots, the rest is erect, simple, leafy. Leaves, according to Mr. Douglas,
for they are almost destroyed in drying, obovato-spathulate, gradually smaller and narrower upwards.
Flowers yellow, very similar to those of S. stenopetalum, as far as can be judged from the dried state of
the plant.
3. S. Douglasii; caule erecto superne ramis recurvis prolifero, foliis lineari-subulatis
acutissimis intus planis dorso subcarinatis margine siccitate membranaceis, cyma dichotoma,
floribus sessilibus decandris, petalis anguste lanceolatis calyce duplo longioribus.
H ab. Common on rocky places of the Columbia to the mountains. Douglas.—Flowers resembling
those of S. spathulifolium and S. stenopetalum, as far as can be judged from the dried specimens; but the
leaves are widely different, and of such a nature that I am doubtful whether the plant should be referred to
this or to the third section: those at the base of the stem, and those on the numerous proliferous shoots on
the upper part of the stem, remain attached by their broad and almost membranaceous bases, they are
thickened in the middle, but thin and scariose at the margin. The root is annual: the plant a span high:
the proliferous shoots, which are entirely confined to the upper half, an inch long.

It is greatly to be regrettéd, that of tins interesting family, from the impossibility of drying them, no
specimens were collected. Species were met with, if I mistake not, by Mr. Drummond in his route, and
certainly by Mr. Douglas on the west side of the Rocky Mountains, as far as the 44th or 45th degree of
north latitude, and at a considerable elevation upon the mountains. The species are probably the same as,
or nearly allied to, those which Mr. Nuttall detected upon the high mountains of the Missouri, and in the
Mandan country:—these are Mammillaria simplex, Haw., M. vivipara, Haw., and Opuntia fragilis, Nutt.
