CATALOGUE. 27 



1 J-2 J' long. Collected by Douglas and Nuttall on the Columbia River, and by 

 Bloomer near Virginia City, Nevada. Found on the Mount Tobin range, 

 Nevada, and in the adjacent Regan's Valley ; 5-6,000 feet altitude ; June. 

 (111.) 



Cadlanthus^ crassicaulis. (Streptanthus, Ton: Stansbury^s Rep., p. 

 384, 1. 1.) Glaucous; stem glabrous, fistular, inflated; leaves oblong, runcinate 

 or runcinate-pinnatitid, with long petioles ; flowers ascending, the dark-purple 

 petals linear, rather obtuse, scarcely a half longer than the very woolly calyx ; 

 siliques elongated, linear, terete ; seeds subcompressed, irregularly angular ; 

 cotyledons very obliquely incumbent. — Stem erect, simple or rarely branched, 

 2-3° high ; leaves mostly radical, the terminal lobes largest and triangular or 

 deltoid ; sepals oblong, 6" long ; petals sHghtly dilated above the short claw ; 

 pods on very short pedicels, ascending, 3-5' long and 11" broad, cylindrical, 

 terminated by the conspicuous stigma-lobes. On dry foot-hills of Nevad and 

 Utah ; known as " Wild Cabbage," and sometimes used as a barely tolerable 

 substitute for the cultivated plant. This fancied affinity to the cauliflower- 

 tribe of more favored regions has suggested the generic name. In flower 

 and fruit, May-July. (112.) 



Caulanthus pilosus. Biennial, pilosely hispid, branched ; leaves 

 petioled, lyrate-pinnatifid, lobes sparsely angular-toothed ; racemes loosely 

 flowered ; flowers greenish-white, spreading ; petals a little exceeding the 

 sepals, oblong, contracted above ; siliques linear, elongated, subterete ; style 

 none, or a mere contraction between the ovary and the somewhat lobed 

 stigma ; seeds oblong, flattened. — A coarse, unsightly plant, 3-4° high, the 



'CAULANTHUS. (See note to Streptanthus, on p. 19.) Sepals large, nearly equally saccate 

 at base. Petals but little longer than the sepals, undulate-crisped, the lamina only a somewhat dilated 

 rhomboidal extension of the broad claw. Anthers linear. Siliques sessile or with a short and thick stipe, 

 terete, elongated ; valves convex, more or less distinctly 1-nerved ; stipe short or none ; stigma 2-lobed, or 

 slightly emarginate. Seeds in one row, oblong, flattened, immarginate or scarcely margined ; cotyledons 

 more or less incumbent. — Stout biennial or perennial herbs; leaves mostly pinnatifid ; flowers in long 

 loose racemes ; pods 3-5' long. 



Though technically to be classed with the Sisymbriw, yet, like Thelypodium, the genus is so closely 

 related to Aralia and Streptanthus that some less artificial arrangement, that would bring them nearer 

 together, is desirable. We refer to it the following additional species : 



C. PBOCEKUS. {Streptantlms, Brew. Froo. Amer. Acad. 6. 519.) Biennial, stout, glabrous and 

 glaucous, 4-6° high ; leaves petioled, coarsely laciniate-pinnatifid ; flowers greenish- white, 6" long ; pod 4' 

 long, terete, acumiaate with the nearly entire style ; cotyledons decidedly incumbent, shorter than the 

 radicle. California. 



C. CouLTERi. {Streptanthus, Gray MSS. S. heterophyllus, Gray, Proc. Amer. Acad. 6. 185, in part, not 

 of Nuttall.) Canline leaves cordate lanceolate, entire or rarely dentate, hispid ; pedicels hispid, spread- 

 ing; sepals oblong-lanceolate, 4" long, often hirsute at base; pods deflexed, the valves nerved; stigma 

 strongly 2-lobed. S. California.
