o T D-mc^ ocarPa (Nutt, mss.) : “ root fibrous and tuberous; radical leaf
3-toliolate, the leaflets reniform and lobed; cauline leaf solitary, 3-parted
the segments entire, obtuse; silique very long.
“Woods of the Oregon, with the preceding.—A small species, remarka-
ble for the great length of its silique, its cuspidate and rather long style, and
capitate stigma. On the receptacle, (as in the preceding,) there remain some
time after inflorescence, 2 filiform denticulations, like abortive stamens.—
Described from a single specimen.” Nutt.
8. D. integrifolia (Nutt. mss.): “ rhizoma tuberous; tall and rather robust;
radical leaves trifoliolate, leaflets roundish-oval; cauline 3, alternate
3-parted or trifoliolate; divisions linear-oblong, acute, entire; siliques rather
short, on long pedicels; petals very large.
“ Plains of Monterey, Upper California.—Stem 12-18 inches high. Petiole
of the solitary radical leaf very long; the leaflets large. Flowers
among the largest of the genus.” Nutt.
9. D. Calif arnica (Nutt, mss.): “ rather robust; leaves trifoliolate, cauline
ones alternate; leaflets ovate or ovdte-lanceolate, crenate or incisely
denticulate, acute; siliques lanceolate-linear, rather long.
“Monterey, Upper California.—About the size of the preceding species
but with smaller flowers. Cauline leaves 2-3, nearly as large as the radical
ones, and similar in form.” Nutt.

Silique broadly linear; valves veiny. Seeds in a double series, margined;
the epiderms loose and more or less corrugated : funiculi partly adnate to
the septum. Lobes of the stigma approximate.—Perennial herbs. Leaves
mostly radical, fleshy, entire or toothed. Flowers rose-color or purple.

Arctic America ! confined to the eastward of Mackenzie’s River, as the preceding
species is to the westward of it. Hook.—Plant 2-4 inches high.
Leaves spatulate-lanceolate. Flowers as large as in Cardamine pratensis"
corymbed: petals purple, rarely white; limb obovate. Siliques about an
inch long, racemose, spreading or pendulous, obtuse. Seeds 6-8 in each cell
strongly corrugated.
10. PHCENICAULIS. Nutt. mss.
“ Calyx colored, nearly equal at the base, much shorter than the entire un-
guiculate petals. Silique ensiform, acuminate, flat, not opening elastically; the
cells about 3-seeded; valves with a prominent central nerve. Seeds large,
in a single series, not margined; funiculi flat, short, dilated and slightly
adnate towards the base. [Cotyledons flat; the radicle not applied to their
edge, but lying a little to one side.]—A low perennial herbaceous plant, with
a thick ascending caudex. Scapes slender. Leaves entire, densely and
stellately tomentose. Flowers in simple corymbose racemes, purple. Siliques
diverging horizontally.”
P. cheiranthoides (Nutt.! mss.)
“ High hills to the east of Wallawallah River, and on rocks on the upper
part of the Oregon.—Stem partly subterranean and descending to a considerable
depth. Leaves oblong-lanceolate, entire; the base attenuated into a
long petiole which is dilated and sheathing at its insertion. Scapes 4-6
inches long, with a few small sessile and partly clasping leaves. Sepals oblong,
obtuse, bright purple on the margin. Petals purple, oblong-oval, the
claws as long as the calyx. Stamens about as long as the calyx. Stigma
nearly sessile, somewhat capitate. Pedicels of the flowers erect, of the fruit
divaricate. Siliques straight 1-14 inch long, obtuse at the base, tapering to a
long point: valves obscurely reticulated : [septumopaque, with a distinct single
or double longitudinal nerve : areolae very tortuous, reticulated.] Seeds
oval, smooth, distant, nearly as broad as the septum.—Allied to Parrya macrocarpa;
but differing in the cuspidate siliques, the few seeds in a single
series, without the loose epidermis.” Nutt.—The cotyledons are not truly
accumbent; but the radicle is applied to the back of one of them, not far
from the edge.
