 Nos. 43, 47, and 48) ; ovules 4-6 (in L. truncatus, 8). 



43. L. leptophyllus, Benth. Slender, 1-2° high, villous with both

 slender petioles 2-3 times longer ; racemes becoming loose, 3 - 10' 

 long ; bracts setaceous, much exceeding the calyx ; pedicels 2 - 3" 

 long ; upper calyx-lip narrow, deeply cleft ; petals 5 - 6" long, " bluish-

 and rocky places; Sacramento Valley and southward. A somewhat 

 broader leaved form occurs. 



44. L. sparsiflorus, Benth. Very slender, 1 - H° high; villous 

 with spreading hairs ; upper leaves much reduced ; leaflets 5-9, linear, 

 ^-1' long, the very slender petioles 2-4 times longer; raceme 3-6' 

 long ; bracts linear-setaceous, shorter than the calyx, subpersistent ; 

 pedicels 1 - 2" long ; upper calyx-lip 2-parted, lower entire ; petals 

 violet, 5" long, the banner shorter; pod ^-1' long. — Sacramento 

 Valley to Southern California; spring. 



45. L. truncatus, Nutt. Slender, 1-2° high, finely pubescent, 

 becoming nearly glabrous ; stipules short, subulate ; leaflets 5-7, 

 linear, attenuated from the truncate or sub-3-toothed apex to the base, 

 f - 1 \' long, smooth above, the petioles but little longer ; raceme 3-6' 

 long; bracts short, linear-subulate, subpersistent; pedicels } 2 — 2" long ; 

 upper calyx-lip 2-cleft, the lower subentire ; petals deep-purple, 4 - 5"

 apex, | - 1 }/ long, usually glabrous above, the petioles 2-3 times 

 longer ; racemes 2-3' long, elongating in fruit ; bracts lanceolate, 

 short, subpersistent ; pedicels slender, 2 - 4/' long ; upper calyx-lip 2- 

 cleft, the lower subentire ; petals blue, 4 - 5" long, the banner with a 

 white or yellow centre ; pods 1 )■ long, 4 - 6-seeded. — Texas ;' spring.
