 Curtis !—Vlant 12-15 inches hish. Leaflets 5-10 lines lon<r. Flowers 3-4 

 lines long. Calyx deeply parted ; the segments lincar-^ubulate, nearly as 

 long as the corolla when the flower first expands. Petals rose-color; the 

 vexillum with deeper minute stripes. Legume an inch or more in length, 

 about 6-secded, with spongy imperfect partitions between the seeds. — A va- 

 riable species in its pubescence and in the size of the leaves. 



27. H. elata (Nmt.l mss.): " sparsely hirsute; stem tall and somewhat 

 branching above; leaves on short petioles; leaflets elliptical oblong, some- 

 what obtuse ; peduncles longer than the leaves ; bract of a single leaflet ; 

 calyx two-thirds the length of the corolla, the segments twice as long as the 

 tube ; legume terete, slender. 



. glabra (Nutt.! mss.): "erect, branching from the base; leaflets oblong 

 and cuneale, rather acute, somewhat fleshy ; peduncles longer than the 

 leaves; calyx nearly as long as the corolla; legume glabrous. 



"Gravelly bars of the Wahlamet and Oregon. May.— Verv near the pre- 

 ceding, but with much smaller and almost white flowers; the leaves are also 

 larger^ and the, stem scarcely branch;'d." Nuttall.—Om specimen of this 

 plant, received from Mr. Nuttall, is about a foot high. It dillers chiefly from 

 some forms of L. sericeus in the distinctly petiolate leaves. 



28. 77. florihunda (Nutt. ! mss.) : " smoothish or pubescent, much branch- 

 ed and decumbent; leaflets efliptical-oblong, the lateral ones narrower; ex- 

 treme branches with unifoliolate leaves; flowers on very short peduncles, 

 approximated towards the extremity of the branchlets; bract of a single 

 leaflet ; legume compressed, few-seeded. 



" Plainsof the Rocky Mountain range, towards the Oregon. June-July. — 

 Also aUied to the two preceding species, but distinguished^ by its numerous 

 almost sessile flowers. Legume about an inch long, 4-5-seeded." Nuttall. 



29. //. pilosa (Nutt.! mss.): "densely clothed with soft hairs, decum- 

 bent and much branched ; leaflets elliptical-oblong, obtuse or slightly acute, 

 branchlets unifoliolate; bract of a single leaf; flowers scattered; peduncles 

 very short ; legume ttattish, few-seeded. 



"With the preceding, which it resembles, but is much smaller. Leaflets 

 3-4 lines long. Peduncles shorter than the leaves. Legume about f of aa 

 inch long." Nuttall.
