9. Desmodium ciliare, DC. Hairy SmaU-leaved Desmodium. 



Stem erect, mostly simple, rather slender, hairy ; leaves crowded, on short hairy petioles ; 

 leaflets (small) ovate or oval, obtuse, rather coriaceous, pubescent and somewhat ciliale ; 

 stipules subulate-linear, rather persistent; lower branches of the panicle mostly elongated; 

 pedicels little longer than the flowers ; legumes with 2-3 semiorbicular or obliquely roundish- 

 obovate hispid joints. — DC. prodr. 2. p. 330 ; Beck, hot. p. 84 ; Darlingt. Jl. Cest. p. 413 ;

Stems 2-3 feet high, commonly several from one root, more or less hairj-. Leaflets 

 about three-fourths of an inch long, and half an inch or more in breadth. Petioles of the upper 

 leaves very short ; those of the lower ones a little longer. Panicle scabrous with short hooked 

 hairs. Calyx hairy ; the upper lip notched : lower tooth lanceolate, one-third longer than the 

 2 oblong, obtuse lateral ones. Corolla and fruit as in the preceding species. 



Sandy fields, hill-sides and copses. August - September. Very near D. Marilandicum, 

 and best distinguished by its hairy stem and leaves, short hairy petioles and pedicels. 



10. Desmodium rigii>um, DC. Rigid Desynodium. 



Stem erect, branching, clothed with a rough pubescence ; leaflets ovate-oblong, obtuse, 

 ciliate, rough above, hairy underneath, the lateral ones smaller, much longer than the hairy 

 petiole ; stipules ovate-lanceolate, acuminate, ciliate, caducous ; racemes paniculate, erect, 

 very long ; pedicels a little longer than the flowers ; legumes with 2 or 3 semiobovate or 

 obliquely ovate hispid joints. — DC. prodr. 2. p. 330 ; Darltngt. Jl. Cest. p. 413 ; Torr. ^ 

 Gr. jl. 1. p. 362. Hedysarum rigidum., Ell. sk. 2. p. 315. 



Stem 2 — 3 feet high, paniculate-branched and somewhat rigid, striate ; the pubescence 

 consisting of short hooked hairs. Leaflets 1-3 inches long, rather coriaceous ; the veins 

 strongly reticulated and elevated. Petiole varying in length from 3 to 8 lines. Flowers 

 small ; the pedicels rather thick. Calyx pubescent ; segments of the caly.x rather acute, 

 lowest one longest. Stamens diadelphous nearly to the base. Legume nearly sessile, 5-8 

 lines long. 



Dry hill-sides and borders of woods in sandy soil ; Island of New-York, Staten Island, 

 and Long Island. August. This species sometimes has the leaves smaller and broader, 

 when it is not easy to distinguish it from D. ciliare. 



11. Desmodium paniculatum, DC. Panicled Des?nodium. 



Whole plant nearly smooth ; stem erect, slender ; petioles about one-third the length of the 

 oblong-lanceolate, rather obtuse leaflets ; stipules subulate, deciduous ; racemes forming a 

 large spreading panicle ; pedicels rather longer than the flower, slender ; legume straight,
