24 CBUCIFERvE. 



with short acute wings, finely reticulated and pubescent, exceeding the 

 thick erect pedicels. — Livermore Valley; also along the borders of 

 marshes at Alameda. 



3. L. oxycarpum, Torr. & Gray. Very slender, the elongated and 

 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% lines 

 broad, the terminal wings tooth-like, short, acute, divergent. — Borders of salt 

 marshes at Vallejo, Oreene; also in subsaline soils east of Wild Oat Creek 

 in the Berkeley Hills, and near Alameda. 



4. L. Oreganum, Howell. Erect, simple or with a few ascending 

 branches, 3 — 6 in. high, ostensibly glabrous (more or less hispidulous 

 under a lens): leaves linear, with a 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 some- 

 what hispidulous or glabrate. — Plentiful in subsaline soil in the Liver- 

 more Valley. March — May. 



H— ■)— Pods faintly or not at all reticulate. 



5. L. nitidum, Nutt. Erect and with few ascending branches, or 

 more diffusely branching from the base, % — V?i ft- high, rather slender, 

 almost glabrous, or the branches distinctly hirsutulous; these racemose 

 almost throughout: lower leaves loosely pinnatifid, segments linear; cau- 

 line often entire: stamens 2 or 4: pods rounded, glabrous and shining, 

 often of a dark purple, or with purple dots, V-,4. lines broad, with a small 

 abrupt sinus between the short terminal teeth. Var. insigne, Greene. 

 Stout, mostly simple, 4 — 8 in. high; fruiting raceme shorter and denser: 

 pods twice as large, round-obovoid. — Very common, especially towards 

 the seaboard. The variety is of the Mt. Diablo Bange. Jan. — June. 



6. L. Menziesii, DC. Low and diffuse, herbage light green, hispid- 

 puberulent or glabrate; branches 3—6 in. long; racemes numerous, 

 rather narrow and dense: leaves of oblong outline, pinnatifid, the seg- 

 ments usually 3-cleft or -toothed: petals 0: pods rounded, 1 — 1% lines 

 broad, glabrous, or around the margin more or less hispidulous, faintly 

 reticulate: teeth at the summit very short and obtuse; pedicels short, 

 ascending or spreading, often very little flattened.— Common, especially 

 by waysides and in hard clayey soil; late flowering, i. e., April — June. 



* * Stouter and taller; pedicels terete. 



7. L. intermedium, Gray. Erect, branching above the middle, %— 

 \% ft. high, puberulent or glabrous: lower leaves 1—2 in. long, toothed 

 or pinnatifid: upper entire or only sparingly toothed, oblanceolate or
