CHEIRANTHUS. 
Tribe 1. Arabidewx DC. Stigma when lobed prolonged over the

scent, flattened parallel to a broad partition or terete. Cotyledons 
accumbent (incumbent to convolute in Chieranthus).

Low perennial herbs with mostly radical entire or toothed 
somewhat fleshy leaves, and rose-colored or purple flowers. Sep- 
als erect, equal or the lateral ones saccate at base. Petals spatu- 
late unguiculate. Anthers usually linear, Styleshort; stigma 
lobes connate. Pods compressed, the valves plane, 1-nerved. 
Seeds in 1 or 2 rows in the cells, large, somewhat compressed, 
orbicular. Cotyledons various.

des Nutt. T. & G. Fl. 1, 89. Cheiranthus Menziesiti Watson Bot. King, 14. 
Caudex stout and branching, the branches densely clothed with the persist- 
ent petioles of former seasons: radical leaves spatulate or oblanceolate, 
entire, 1-4 inches long, persistent, canescent, with a dense stellate pubesce- 
nce, the petioles nearly glabrous: scape-like stems several from each branch 
of the caudex, twice longer than the radical leaves, nearly glabrous, often 
leafy-bracted below: flowers large dark purple or red, to ochroleucous, in 
rather dense many-flowered racemes: pods spreading, on short, stout ped- 
icels, 1-2 inches long, 1-2 lines broad, not carinate, attenuate to the slen- 
der style, glabrous few-seeded. On stony hillsides, northern California 
and Nevada to Brit. Columbia east of the Cascade Mountains.

2 CHEIRANTHUS L. Gen.n. 815. 
Cheiranthus and Erysimum of authors. 
Biennial or perennial herbs with narrow entire or sparingly- 
toothed leaves and yellow or purple flowers in simple racemes. 
Sepals erect, oblong to linear-oblong, equal at base or the lateral 
ones somewhat saccaté. Petals commonly large with broad obo- 
vate blade and slender elongated claw. Stamens 6, free and un- 
appendaged. Pods strongly compressed, broadly linear with flat 
l-nerved valves or narrow and quadrangular with convex and 
more or less distinctly keeled valves. Seeds numerous, oblong 
and turgid, or suborbicular and flattened or winged. Cotyledons 
incumbent or accumbent or the radical very oblique. 
* Petals 2-216 lines long, yellow: pods subterete, 5-10 lines long: 
cotyledons incumbent or nearly so. 
C. turritoides Lam. Encycel. ii. 716. Erysimum cheiranthoides L. 
Stem erect, subterete, simple or with few subterminal branches: leaves 
lanceolate, acute at each end, entire or remotely and obscurely denticu- 
late, 1-3 inches long, thin, green on both faces, sparsely and finely pubes- 
cent: flowers small, yellow: pods obtusely angled, 5-10 lines long, on 
somewhat spreading and rather slender pedicels, glabrous, slenderly short-

nent.

subterete or obviously 4-angled, not strongly compressed, 1-4 inches
