C. asper. Schlecht. et Cham, in Linnoea, v. 1. p. 14.
Radix, ut videtur, animus. Caulis basi ascendens et ramosus, demum erectus, pedalis et ultra, acute angula-
tus, tactu subscaber, pube bipartita subcanescens. Folia remotiuscula, 3-5-pollioaria, patentia, lineari-lanceo-
lata, magis minusve dentata vel integerrima, basi in petiolum longe attenuata, pube bipartita, arctissime appressa,
strigosa: suprema magis angusta, minus basi attenuata. Flores majusculi, in capitulum duas uncias
latum dense racemosi, flavi. Pedicelli 5-6 lineas longi, appresse pilosi. Calyx etiam simili modo pilosus,
sepalis linearibus, 2 basi saccatis. Pet ala limbo ovato, ungue sepalis longi ore. Germen lineare, rectum. Stylus
crassiusculus, lineam longus. Stigma mediocre, capitatum, bilobum, lobis rotundatis. Siliquce nostris ex-
amplanbus absunt: sed, Chamissonis fide, “ 15 circiter lin. longse, lineam late, compressa); plurimis ovulis
abortu haud perfectis, pauca modo aderant semina in quoque loculo; valvulse medio nervo ext us prominente
a basi ad apicem sunt notate. Stylus siliquam terminans, brevis, vix semilineares, crassus, stigmate capitato,
indistincte bilobo. Semen lineam longum, compressum; cotyledcm.es accumbentes.”
EIab. Common on rocky places of the Columbia, near the sea; and at Puget Sound. Douglas. Chamisso
found it on the coast of California.—I regret that I do not possess the fruit of this plant; but there can be no
question of the accuracy of Chamisso and Schlechtendal, who assure us that the cotyledons are accumbent.
It must therefore be separated from Erysimum, with the species of which, and especially with E. lanceolatum,
as is well observed, it bears a very close affinity: It is quite a different plant from the Erysimum asperum,
De Cand., the CheirantJms asper of Nuttall, and which is also supposed to be the Erysimum lanceolatum of
Pursh; but I know not upon what authority. I am indebted for specimens to M. de Chamisso, which agree
in every respect with those from Mr. Douglas: both are remarkable for the gTeat attenuation of the base of
the leaves. It has been found' by no other of our North American travellers: but is now cultivated in the
gardens of the Horticultural Society, from seeds sent by Mr. Douglas from the Columbia.

incumbent cotyledons, and is therefore removed to the Notorhizk®.
