long ; calyx nearly equalling the petals, the lips subequal and toothed, 

 bracelets setaceous ; petals pale-red, the rounded banner with a dark- 

 purple centre ; keel naked ; ovules 4 - 6 ; pods densely villous, in a 

 crowded cylindrical spike, V long, 2-4-seeded. — Dry sandy barrens ; 

 Georgia to Florida and Alabama ; April. 



2. L. diffusus, Nutt. Resembling the last ; procumbent ; pubes- 

 cence shorter, appressed, rarely subspreading ; leaves short-oblong, 

 1 — 3' long, obtuse and.mucronulate, sometimes acutish, mostly exceed- 

 ing the petioles ; stipules 3 - 9" long ; bracts lanceolate or oblong, 

 shorter than the calyx ; calyx considerably shorter than the petals, 

 and with shorter bractlefs; flowers mostly smaller, 4 - 6" long, light- 

 blue, the banner with a greenish-yellow centre, less decidedly rounded, 

 or acutish; ovules 6-10; pod densely covered with shorter stiffish 

 hairs. — North Carolina to Florida. 



* * Perennials; leaflets 5 - 15. — Spec. 3-39. 

 f Shrubby, at least at base, tall, branched, and leafy ; pubescence 

 silky, mostly appressed; leaflets 7- 11 ; petioles rarely much ex- 

 ceeding the leaves ; bracts deciduous ; flowers large ; calyx-lips 

 nearly equal ; ovules mostly 8-12. 



3. L. arboreus, Sims. Shrubby and often 4-10 6 high; pubes- 

 cence not dense, short and silky, mostly appressed; leaflets 7-11, 

 mostly 9, glabrate above, narrowly lanceolate, J -If long, acute ; ra- 

 ceme loose, 3-8' long ; bracts linear, equalling the calyx ; flowers 

 verticillate or subscattered, sulphur-yellow, fragrant ; pedicels 3 - 4" 

 long ; calyx-lips broad, entire or the upper obscurely 2-toothed ; bract- 

 lets minute ; petals 6 — 8" long, equal, keel slightly ciliate ; pod 

 10-12- (rarely 8-) seeded, 1^-3' long, 4-6" wide, pubescent. — 

 California, common, from Sacramento Valley to San Diego ; April to 

 August. Specimens from Punta de los Reyes (Bigelow) are remark- 

 able for their more abundant villous pubescence, spreading upon the stem. 



4. L. albifrons, Benth. Stems 1-4° high ; pubescence dense, 

 silky, appressed ; leaflets 7-9, cuneate-obovate, %-V long, obtuse and 

 mucronulate, or acutish, silky on both sides ; racemes loose ; bracts 

 lanceolate, shorter than the calyx ; flowers subverticillate, blue, violet, 

 pink, or white ; pedicels 2 - 3" long ; calyx with small setaceous bract- 

 lets, upper lip deeply cleft, the lower subentire ; petals 6" long, equal 

 or the banner slightly shorter, keel naked or ciliate ; ovules 6 - 8 ; pod 

 \\' long, 4 - 6-seeded, silky. — From Oregon (Hall) to Southern Cali-
