p. intermedia : pubescent; stem erect; leaves all liifuliolate; leaflets 

 strongly ruifose, middle one roundiNh, lateral ones ovate. 



y. volubili.s\- pubescent; stem twining (2-4 feet long); upper leaves tri- 

 foliolate ; lowest ones unifoliolale; leaflets roundish or broadly ovate, some- 

 times rather acute, rugosely veined ; racemes iew-flowered, shorter than the 

 leaves. — R. dillormis, DC. I. c. Glycine tomentosa p. volubilis, Michx.! I.e.

i.erecta: velvety-pubescent; stem erect (1-2 feet high) ; leaves trifolio- 

 late ; leaflets oval or oblong, nearly acute, slightly rugose ; racemes usually- 

 shorter but often longer than the petioles. — R. erecta, DC. I. c. Trifolium

 Bay, Florida, Dr. Bnrroics ! y. North Carolina! to Georgia. <5. Maryland! 

 to Florida! and Louisiana ! c. Si. Mary's, Florida, Baldwin. — Leaflets, 

 particularlv on the lower surface, and the calyx, sprinkled with minute yel- 

 lowish resinous dots, w^hich are very distinct in the more glabrous varieties, 

 but are concealed by the pubescence in 6. and probably also in c. Calyx two- 

 thirds the length of the corolla ; segments lanceolate, strongly veined ; upper 

 segment deeply 2-cleft. Vexiilum orbicular or broadly obovate, generally 

 (particularly in y. and i.) with 2 very minute gibbous projections near the 

 base of the limb. Wings a little longer than the keel. Legume about J of 

 an inch long and 3 lines Avide. Seeds mottled. — From a careful examina- 

 tion of an extensive series of specimens, Ave are persuaded that all the varie- 

 ties described above are merely forms of one species, as indeed they were 

 regarded by Michaux. The var. monophylla sometimes bears trifoliolate 

 leaves, and late in the season produces long axillary branches, which are 

 sometimes twining. The racemes are extremely variable in length; but we 

 have never seen them so long as they are said to occur in the var. moUissima. 



4. R. latifolia (Nutt. ! mss.) : softly hirsute ; stem angular, twining, sti- 

 pules subulate-lanceolate; leaves trifoliolate; leaflets somewhat rhomboidal, 

 dilated, u?uallv obtuse ; racemes longer than the leaves, many-flowered ; 

 flowers rather distant, on very short pedicels; segments of the calvx at length 

 oblong-lanceolate, acuminate ; vexiilum obovate; legume oval-oblong. 



p.l more glabrous ; leaflets smaller, orbicular-obovate, with a short abrupt 

 acumination. and conspicuously mucronate; racemes about as long as the 

 leaves; vexiilum orbicular, with minute gibbous projections on the inside. 



Forests of Arkansas, Nultall ! Dr. Ijeaveinrorth ! Red River, Louisi- 

 ana, Dr. Hale ! — Stem 3-4 feet long, clothed with a soft pubescence. Leaf- 

 lets li inch (in P. scarcely 1 inch) in diameter, canescent, minutely dotted 

 beneath; the terminal one nearly orbicular; the lateral ones more or less 

 rhomboidal-ovatc. Raceme 4-8 mches long, 10-14-flowered ; the flowers 

 scattered, nearly half an inch long. Corolla bright yellow. Legume three- 

 fourths of an inch long, and one-third of an inch wide. — Scarcely distinct 

 from an unnamed West Indian species in our herbarium.
