1. T. curvipes (Hook.): radical leaves pinnatifid or toothed ; cauline ones
lanceolate or linear; silicles roundish-obovate, obscurely crenate, nearly glabrous
; margin broadly winged, entire or perforated with small holes ; petals
shorter than the calyx—Hook. 1. c. t. 18.7. A ; Fisch. & Meyer, bid. sem.

branched, erect, 6-8 inches to a foot high, somewhat leafy. Leaves mostly
radical, spreading. Petals linear-oblong. Silicle about 24 lines long. Hook.
2. T. elegans (Fisch. & Meyer) : petals nearly twice as long as the calyx;
silicles orbicular-obovate, membranaceously winged; the wing (often) perforated

California, Douglas! Deppe. (ex Fisch. 4 Meyer.)—Stem 12-18 inches
high, branching, nearly glabrous. Leaves in 0. lanceolate, sagittate, repandly
toothed ; in y. linear, the upper ones almost subulate and sagittate-clasping.
Silicles 2J lines long ; the winged margin perforated with a row of 12-14
oblong holes, or marked with thin diaphanous spots, the opaque coriaceous
substance of the centre extending between them, and thus giving the sEicle
a radiated appearance.
3. T. pulchellus (Fisch. & Meyer): petals longer than'the calyx ; silicles.
glabrous, the wing not perforated, truncated at the apex; style much exserted.

California—Petals white, or somewhat violaceous. Near T. curvipes.

4. T. crenatus (Nutt.! mss.): “ petals about as long as the calyx; silicles.
orbicular-obovate, crenate, glabrous, slightly emarginate, membranaceously
winged; the wing perforated; style not exserted; leaves linear-lanceolate,
runcinately and remotely denticulate.
“ St. Barbara, California, March-Apiil.—Stem 12-14 inches high, branching
above. Leaves an inch long; the lower ones somewhat hirsute. Silicles
abouthalf as large as in T. curvipes; the wing more or less perforated.” Nutt.
5. T. laciniatus (Nutt.! mss.): “petals as long as the calyx; silicles
elliptical, glabrous, winged; the wing entire or crenate, not perforated, entire
at the apex, and acuminate with the conspicuous style; leaves Enear, remotely
and incisely toothed.
“ With the preceding.—Decumbent, deep green and glabrous. Stem
about a foot long. Leaves 14 inch long, and scarcely a line wide; teeth
long and subulate. Silicile about 2 lines long, acute at each end ; the wing
diaphanous.” Nutt.
* * Silicles slightly doubly convex, wingless.
6. T. oblongifolius (Nutt.! mss.): “petals about twice as long as the calyx;
silicles nearly orbicular, wingless, hispid with uncinate hairs; leaves oblong,
toothed, and (with the lower part of the stem) densely and steEately hirsute.
“Rocky banks of the Oregon, near the junction of the Wahlamet.—
About a foot high, much branched, sometimes partly decumbent. Radical
leaves attenuate into a short petiole at the base; cauline sessile. Petals cuneiform,
rather conspicuous. Silicles about 14 line long, rather acute at the
base, very obtuse at the summit, and without a notch: style very short, but
distinct.” Nutt.

7. T. pusillus (Hook.) : flowers apetalous ; sihcles nearly orbicular, wing-
less, hispid with uncinate hairs; leaves oblong, toothed, and (with the lower
part of the stem) steEately hirsute.—Hook.! ic. t. 43.
Monterey, California, Douglas ! Banks of the Oregon, with the precedin
g Nuttall. April.—Stems filiform, branching from the base, .3-5 inches
long. Leaves about half an inch long, ovate and oblong, sparingly toothed.
Flowers very minute. Silicles scarcely a line in length, rather acute at the
base: style very short.—Nearly related to the preceding; but much smaEer
and more slender, the sEicles about halt' the size, and the flowers apetalous.

excluding Cakile, which he incorrectly says has the cotyledons (at least in the upper
cell) always incumbent. See Torr. in aim. lyc. New-York, 4. p. 91.
