- Hudson s Bay to the Rocky Mountains. Shore of Lake Superior Dr.
Pitcher! 0. Rocks, Watertown, New-York! May.— Stem 2 feet Ligh
strict terete, simple. Leaves about an inch long. Pedicels of the fruit 3-6
lines long. Siliques 2—3 inches long and scarcely half a line wide, crowned
with the nearly sessile stigma. Seeds with a winged margin. Funiculi slen-
der, about as long as the seed. (Flowers pale sulphur-color, Hook.)—Perhaps
distinct from the European plant, of which our specimens are not sufficiently
advanced for full comparison. We have not seen the fruit in 0.. which has
narrower and rather acute leaves, and may prove to be a distinct species.
2. T. macrocarpa (Nutt.! mss.): “ radical leaves runcinate-dentate, or
simply toothed, hairy ; cauline ones lanceolate, sagittate, crowded, glabrous;
siliques strietly erect, very long and narrow.
“ Rocky situations, in the woods of Oregon.—Stem 3—4 feet high terete
glabrous, simple. Radical leaves sparingly hirsute with stellate hairs ; cauline
ones crowded on the lower part of the stem. Sepals linear. Petals lin-
#ear and narrow, yellowish-white. Stigma capitate, somewhat 2-lobed.
Silique about 4 inches long, rigidly erect and appressed. Seeds somewhat
quadrate slightly margined.” Nutt.—We should rather consider this a spe-
cies of Arabis, as the seeds are placed mostly in a single row in the very
narrow silique. J
3. T. spathulata (Nutt, mss.): “ radical leaves broadly spatulate-oval,
repandly toothed, hirsute ; cauline oblong-lanceolate, clasping: siliques very
long, erect.
“Woods of the Oregon.—Stem 12-18 inches high, branched from near
the base. Upper leaves much smaller than the lower ones. Petals narrow
a little longer than the calyx. Siliques about 3 inches long.” Nutt.
4. T. mollis (Hook.) : erect, hirsute with soft spreading hairs; lower
leaves spatulate, sinuate-toothed ; the upper ones lanceolate, sagittate at the
base; siliques elongated, linear, strictly erect. Hook, fl. Bor.-Am. 1. p. 40.
Arctic America.—© A foot or more high. Flowers white, capitate-co-
rymbed. Petals cuneiform, nearly twice as long as the calyx.—Habit of
Arabis hirsuta. Hook.
5. T. stricta (Graham) : erect, glabrous; leaves lanceolate; radical ones
petioled, toothed ; cauline ones sagittate, partly clasping, somewhat toothed;
siliques linear, elongated, and (like the flowers) strictly erect. Hook.—

Oregon, Rocky Mountains.—® Habit of the preceding, but more slender.
Flowers white: petals obovate, emarginate, twice the length of the
calyx. Silique 2-3 inches long, rather broadly linear; style short, much
narrower than the valves: stigma minute. Hook.
6. T. patula (Graham): erect; leaves lanceolate; radical ones petioled,
toothed or nearly entire, pubescent; cauline sagittate, partly clasping, glabrous
(or sparingly pubescent) ; flowers spreading; siliques linear, elongated,
much spreading.— Graham, in Edinb. jour. 1. c ; Hook. ! ft. Bor.-Am.

Greenland and Hudson’s Bay to the Rocky Mountains! and Oregon.—©
Stem 12-18 inches high, simple. Leaves an inch in length; the radical and
lower cauline ones stellately hirsute. Flowers rather large, purplish or rose-
color. Siliques rather broadly linear, about 3 inches long, straight or a little
curved; valves obtuse: stigma sessile. Seeds very distinctly 2-rowed, margined.
7. T. retrofracta (Hook.): erect, canescently pubescent (or nearly glabrous)
; leaves lanceolate; radical ones petioled, toothed; cauline sagittate,
partly clasping; flowers nodding; siliques linear, elongated, and (with the
pedicels) refracted. Hook. fl. Bor.-Am. 1. p. 41. Arabis retrofracta, Graham,

Hudson’s Bay to the Rocky Mountains; north to lat. 68°.—Flowers nearly
white, or with a purplish tinge.—The (margined) seeds in a young state,
are in two rows, but in the mature fruit they are in a single series. Hook.
Graham.
8. T. brachycarpa: glabrous and glaucous ; radical leaves spatulate,
toothed; cauline ones linear-lanceolate, acute, sagittate and somewhat clasping
; siliques short, rather broadly linear; pedicels of the flowers pendulous,
o f the fruit spreading or ascending.
Fort Gratiot, Michigan, and Shore of Lake Superior, Dr. Pitcher!—©
Stem 1-2 feet high, simple or sparingly branched above. Radical leaves pubescent.
Flowers rather large, pale purple; the pedicels mostly bent downward.
Silique about an inch long and nearly a line wide, straight or somewhat
curved, usually spreading at right angles to the stem. Seeds mostly
abortive, in 2 distinct rows when young; the ripe and perfect ones nearly as
broad as the cell, winged on the margin.—The whole plant is sometimes of
a purple color. Nearly related to the preceding; but distinguished by its
short siliques.
9. 71? diffusa (Hook.): very glabrous and glaucous; stem diffusely
branched; radical leaves spatulate, nearly entire; cauline sagittate, slightly
toothed; siliques linear, spreading, twice as long as the pedicels. Hook. fl.

Shores of the Arctic Sea.—Stems many from the same rodt, a span high.
Cauline leaves about an inch long, obtuse. Flowers small. Petals half the
length of the calyx, white. Silique scarcely an inch long.—Perhaps an Arabis.
