Quite different fromthe5'.»iacuZates,Nutt.,from the ohtusifolius. Hook. Bot. Mag. t. 8317, as well as from
the S . hyacinthoides. Hook. Bot. Mag. t. 3516. The lower part of the plant is always more or less hispid,
the leaves pinnatifid (the uppermost ones sometimes excepted), with the teeth or segments terminated by a
gland ; the flowers (of the same colour as the last-mentioned handsome species) never drooping, but secund ;
the siliqua always curved, glabrous.

H a b . Snake Country, about Thomas’ Fort. {Tolmie.)— An erect, rather stout plant, a foot to IS inches
high, glabrous, except in the petioles of the lower leaves, which are distantly ciliated. Stem-leaves strongly
sagittate, in our specimens 4-5 inches long ; but in general 2-3 inches.

The few specimens of this plant in our collection appear to have the habit and character of Streptanthus.
They are small, 6-8 inches high, simple, iinbranched ; the cauline leaves sessile, but not amplexicaul, nor in
any way auricled at the base. The flowers are yellow, but the anthers have a purplish tinge. Germen and
young fruit (which is erect) hairy ; style evident ; stigma capitate.

Hab. Pine Creek, in the Snake Country. ( 7 ’oMfe.)_Veryfine specimens of this plant are in the beautiful
collection of Mr Tolmie, from the Snake Country, which enable ns to give a figure of it. Radical leaves
large, oblongo-spatbulate, hoary, with minute, dense, stellated down, tapering into petioles, which are dilated
at the base, quite destitute of pubescence, glossy, and of a bright straw-colour. Scapes, as they may be
called, (rather than stems,) scarcely twice the length of the root-leaves, nearly glabrous, as are the small
oblong leaves which they bear themselves. Corymbs of many large bright purple flowers. Young siliquæ
spreading.*

• Since the above was in type, we have had the pleasure of seeing the fruit of this beautiful plant, sent to Dr
Boott by Mr Nuttall, as his PhcenocaulU cheiranthoides. This fruit indeed differs (as may be seen from that which
we have now added to our figure) from Hesperis (wc more particularly allude to II. aprica), in the pods being
broader, fewer, about (3)-seeded, the seeds without margin ; and in having the cotyledons accumbent ; though in
our seed, which had a third imperfect cotyledon, the cotyledons were incumbent. In every other respect the flowers
and the fruit quite agree with HesperU, on which account we are led, for the present, to continue it in that genua.
