274 CRUCIFEE^. 



pubescence of the preceding, bnt mncli smaller, the branches at length 

 ascending: leaves narrowly linear, entire or with a few narrow divaricate 

 linear lobes: petals little exceeding the sepals or wanting: pods rounded, 

 1}4 lines broad, emarginate, with short aciite wings, finely reticulated 

 and pubescent, exceeding the thick erect pedicels. — Originally found in 

 western Nevada, in alkaline soil, but common in the Livermore Valley, 

 also along the borders of marshes at Alameda. 



3. L. oxycarpum, T. & G. Fl. i. 116 (1838). Very slender, the elon- 

 gated and loosely racemose branches decumbent or assurgent, nearly 

 glabrous: leaves linear, with a few linear segments or entire: sepals 

 caducous: petals 0: stamens 2: pods on slender deflexed pedicels, 

 glabrous, rounded, 1^4, lines broad, the terminal wings tooth-like, short, 

 acute, divergent. — Borders of salt marshes at Alameda, Vallejo, Greene; 

 also in subsaline soils east of Wild Gat Creek in the Berkeley Hills. 



4. L. Oreg'aiium, Howell (1887): L. oxycarpum, var. (?) stricium, 

 Wats. Erect, simple or with few ascending branches, 3 — 6 in. high, 

 ostensibly glabrous (more or less hispidulous under a lens): leaves 

 linear, with few linear segments or entire: sepals and petals less 

 fugacious: stamens 4: pods round-ovoid, 2 lines broad, the terminal 

 teeth more or less prominent and divergent, the body somewhat hispidu- 

 lous or glabrate.— Plentiful in subsaline soil in the Livermore Valley; 

 also at San Diego, Cleveland, and San Bernardino, Parish, beyond our 

 limits. The type is from southern Oregon, and has pods less distinctly 

 reticulate, with shorter and less prominent wings; but this and the Cali- 

 fornian plants are not specifically different. 



-1— -i- Pods faintly or not at all reticulate. 



5. L. iiitidum, Nutt'; T. & Q. Fl. i. 116 (1838): L. leiocarpum, H. & A. 

 (1840). Erect and with few ascending branches, or more diffusely 

 branching from the base, %—!% ft. high, rather slender, almost glab- 

 rous, or the branches distinctly hirsutulous; these racemose almost 

 throughout: lower leaves loosely pinnatifid, segments linear; cauline 

 often entire: petals often present, white: stamens 2 or 4: pods rounded, 

 glabrous and shining, often of a dark purple, or with minute purple 

 dots, 1% lines broad, with a small abrupt sinus between the short 

 terminal teeth. Var. iiisigiie. Stoutish and mostly simple, 4—8 in. 

 high, the mostly solitary fnaiting raceme shorter and denser: pods twice 

 as large, round-obovoid.— Very common, especially toward the seaboard, 

 in the middle and southern parts of the State. The earliest flowers, in the 

 Bay region, appearing in January, have conspicuous petals, but are often 

 sterile; the later and fertile are mostly apetalous. Southward the petals 

 are always present. The variety is of the Mt. Diablo Eange, east of 

 Livermore, Greene; and toward the base of the Sierra, San/ord.
