On the sea-shore from Monterey to Mendocino Co., usually stunted and the base of the stems 

 crowded with the persistent petioles of old leaves. It seems also to extend to sandy hills a few 

 miles from the coast, where it is taller and more slender, having much the habit of Erysimum 

 asperum, with which immature specimens may be confounded. 



9. CAULANTHUS, Watson. 



Pod terete, elongated, sessile upon the receptacle ; valves 1 -nerved. Seeds in one 



row, oblong, somewhat flattened, scarcely or not at all margined ; cotyledons more 



or less incumbent. Sepals large, nearly equally saccate at base. Petals but little 



longer, undulately crisped, the blade only a somewhat dilated rhomboidal extension 



of the broad claw. Anthers linear, sagittate at base, curved : filaments included. 



Stigma somewhat 2-lobed. • — Stout biennials ; with pinnatifid or toothed leaves, 



and purple or greenish- white flowers. — Bot. King Exp. 27.

 lines long, on ascending pedicels half as long : pod terete, very slender, 3 to 5 

 inches long, less than a line broad, pointed, erect or somewhat spreading : stigma

Rich clay soils from Monte Diablo to Pacheco Pass ; locally known as "Wild Cabbage" and 

 sometimes used as a poor potherb. 



2. C. Coulteri, Watson, 1. c. Mostly hispid : stems rather slender, 1 to 2 feet 

 high, simple or branched : leaves mostly dentate, sessile, the radical broadly spatu- 

 late and sinuately toothed ; cauline oblong-lanceolate, clasping with a cordate base ; 

 the uppermost entire : sepals 3 to 4 lines long, broad, acute, hispid : pod straight, 

 terete, 3 to 4 inches long, nearly 1| hues broad, pendent upon the hispid pedicel, 

 beaked by the stout style : stigma 2-lobed. — Streptanthus heterophyllus, Gray, 1. c, 

 in part, not of Nuttall. • 



Southern California {Coulter) ; Fort Tejon, Xantus. 



3. C. pilosus, Watson, 1. c. Somewhat pilosely hispid, at least at base : stout,

 angular-toothed : flowers spreading, in a loose raceme, greenish white, the oblong 

 petals narrowed above, 4 lines long ; calyx slightly hairy : pod slender, 3 to 5 inches 

 long : stigma slightly 2-lobed, nearly sessile.

 erect, 2 to 3 feet high, rarely branched : leaves mostly radical, petioled, runcinate or 

 runcinate-pinnatifid : flowers 6 lines long, dark purple ; calyx very woolly : pod 

 terete, 3 to 5 inches long, \\ lines broad, ascending on very short pedicels : stigma 

 2-lobed, sessile. — Streptanthus crassicaulis, Torrey, Stansb. Eep. 384, t. 1. 



From the eastern base of the Sierra Nevada to Utah, on dry foot-hills ; also known as " Wild
