 brous or minutely pubescent on the veins. 



In dry rich soil, S. Carolina! to Florida! and Louisiana! P. North Ca- 

 rolina! to Louisiana! and Arkansas! Aug.-Oct. — Stem 2-4 feet hiirli. 

 Petioles 1-3 incites long. Leaflets 2-3 inches long, very thick and tiim, 

 sometimes a little narrowed towards the apex but obtuse. Panicle very 

 large : pedicels as long as the flowers. Joints of the legume about 3 lines 

 in length, scarcely convex on the back when mature. — We have a f^jrm of 

 this .species which greatly resembles some varieties of D. viridiflorum, 

 excej)t diat they want the tomentose puliescence of the lower surface of the 

 leaves. Our smoother variety (which uilhrs verv' slightly from the jjlant in 

 Elliott's herbarium) is often taken for D. liEvigatum, but it does not accord 

 with the character of that s])ecies. 



10. D. Ifevigatum (DC): very smooth; stem simple, erect, somewhat 

 glaucous; loaves on long petioles; leiiiiets ovate, acute; stipules subulate, 

 minute and deciduous; panicle teruiinal, nearly simple; flowers by pairs 

 upon lomi pedicels ; bracts ovate, acute, sht)rter tiian the flower-buds. Au<<.

"In the forests of New Jersey, rare. — Ratiier large, and the smoothest of 

 the North American species. Lower petioles about 3 inches long; the 

 larger leaflets 3 inches long and li broad, everywhere perfectly smooth, 

 somewhat glaucous beneath, sometimes elliptic-ovate, constantly diminishing 

 in size upward* : the stem attenuated into the terminal and ra<-pmose ])anl- 

 cle; rachis of the jjanicle and the peduncles minutely pubescent : lowest seg- 

 ment of the calyx conspicuously elongated. The fruit I have not seen. Al- 

 lied to H. cuspidalum but iierfectlj' distinct." Nult. — We have copied Mr. 

 Nuttall's description entire, not having seen tliis species, unless we have 

 mistaken it fi^r a fijrm of D. cuspidatum, from which it ai»[)ears to difler only 

 in having smaller stipules and bracts. Elliott's jdant is, ^\-e suspect, not 

 distinct from D. cuspidatum. 



11. D. glahellum (DC): stem erect, nearly glabrous; leaflets (small) 

 ovate, obtuse, scabrous-pubescent on both sides ; stipules subulate, minute ; 

 panicle terminal ; upper lip of the calyx entire; the lower tooth longest; 

 legume stipitate, nearly straight on the back, minutely hispid, with about 4 

 semi-rhomboidal reticulated joints. — DC. prodr. 2. p. 329. Hedysarum

In shady places, S. Carolina, Michaux! Elliott. N. Carolina, Mr. Cvr- 

 tis ! August-Sept. — Resembles D. Marilandicum in foliage, although the 

 leaflets are often much larger and scabrous with appressed hairs, but the 

 legumes are very like tliose of D. paniculatum. We have apparently a 

 larger form of this s])ecies from Florida, but the fruit is wanting : perhajis it 

 is rather a small-leaved D. DiUenii. 



12. D. Marilandicum (Boott ! mss.) : stem erect, simple, slender, nearly 

 glabrous ; leaflets (small) ovate, very obtuse, often slightly cordate, thin ; 

 petioles as long as the lateral leaflets, glabrous ; stipules Ismceolate-subulale, 

 caducous ; panicle elongated, scabrous-puberulent ; bracts lanceolate-ovate, 

 very small ; upper lip of the calyx ratlier shortest, emarginate ; the lower
