3. L. oxycarpum, Torr, & Gray. Nearly smooth : stems sleiuler, aseendiug, 

 simple or biuneliea, 3 to 6 inches high: leaves linear, pinmitilid with a lew nar 

 rowly linear or lilit'orm se-^ments or entire : raceme lax, elongated : sepals uneijnal ; 

 soon deciduous: i)etals none: stamens 2: ])ods smooth, rounded, 1 J lines hroad, 

 nodding on slender pcdia-ls as long as the pod, the hroad and acute teeth short and 

 divergent. — Kl. i. IK). 



Var. (() Strictum, Watson. lSei)als green, ijersistent : fruiting i-acemes crowded, 

 the pedicels erect : wings less acute anil spreading : lobes of the leaves less elongated. 

 Vallejo, Greene. Also \>y Douijlas and Coaltcr, urobably in the same region. The variety lias 

 been collected only by Kalian, near riacerville. and is liardly referable to this species. 



a- +. ]*od not reticulated or scarcely so. 



4. L. nitidum, Nult. Cilahrous or somewhat pubescent : stems simple or 

 branched, 3 to 1(3 inches high: leaves pinnately cut into narrow hnear acuuanate 

 segments, the uppermost often entire : petals pre.sent, small : pods in a loose raceme, 

 spreading, glabrous and shining, rounded, 1 A to 2 lines broad, acutely margined; 

 the wings sliort, obtu.se ajid slightly spreading: peilicels 1 or 2 lines long : seeds 

 often ash-colored. — Torr. Aj Gray, ¥1 i. IIG. L. Uiocarpuvi, Hook. & Arn. Jiot.

Ill winter and early spring, I'roia above San Francisco to Los Angeles. 



5. L. Menziesii, IX^. Hispid or pubescent : stems 3 to (i inches high, branched : 

 leaves oblong, all pinnatilid with short oblong or spatulate acutish segments, which 

 are rarely sparingly toothed : petals none : poils ghibrous, rounded, 1 to 1| lines 

 broad, not margined except by the short very obtuse teeth at the summit : pedicels 

 spreading cjr recurved, 1 or 2 lines long, slender and often scarcely llattened. —

Santa Harbara (Niillall) U> Los Angeles (linwer) ; r<nadahi|ie Island, Pulvier. Theso sj)eci- 

 inens accord with others raised from seeds cultivated under the name in the garden at Geneva 

 prior to 1840, and with \h' Oandolle's description based upon the original specimens of Men- 

 zies from "California." The Oregon plant referred to this species has been for the most jmit 

 L. intermedium, though the one .so named by Torrey in Bot. Wilkes V^xy. is apparently L. I'ir- 

 ijiuicum with unusually deeply pinnatilid leaves. 



6. L. lasiocarpum, Nutt. Eoughly ])uberulent (n- pubescent with short spread- 

 ing hairs : steni.s rather stout, branched, 3 to 10 inches high, decuiul)ent : lower 

 leaves 3 to 4 inches long, luore or less ciliolate at least on the ])etioles, jtinnate, with 

 ovate to oblong s[)aiingly toothed segments ; upper leaves 1 to 2 inches long, incisely 

 pinnatiful with narrow lobes, or the uppermost entire : petals none or very small : 

 stamens 2 : pods rounded, l.l to 2 lines broad, hisi)id on the margin, winged at the 

 apex with short very obtuse"" teeth, crowdeil in a narrow raceme oji short ascending 

 or horizontal pedicels. ■ — Torr. & Gray, I'l. i. 115. 



Santa Barbara {Nutlall) ; Guadalui)e Island, Palmer. Closely allied to the last species. 



L. WuKJHTil, Gray. A very similar species, hirsute witb spreading liairs ; leaves pinnatilid 

 or toothed ; iwds hispid, rather broadly winged at the sumnut. Of tiie Uio Grande Valley, ranging 

 westward nearly to the Colorado ; a[)peais to be in N. W. Nevada, Torrey, Lcmmon.

7. L. flavum, Torrey. (ilalirous, decundjcnt, dill'usely branch*'d : stems 3 to (> 

 inches long : radical leaves pinnatiliil with short obtuse lobes ; cauline h;aves few, 

 oblanceolate, acutely tootlied or entire : racemes short, nearly sessile : petals bright 

 yellow : pods orbicular, a line broad or more, shortly winged with broad divergent 

 acutish teeth, on spreading or deflexed pedicels 2 to 4 lines long : style nearly as 

 long as the pod. — Pacif. 11. Rep. iv. 67 ; Watson, Bot. King Exp. 30. 



On the Mohave River (Fremtmt, Bigeloxv) ; also about Humboldt Lake and in the upper valley 

 of the Humboldt River, N. Nevada.
