9. Desmodium ciliare, DC. Hairy Small-leaved Desmodimn. 



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

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

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

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

 obovate hispid joints. — DC. prodr. 2. j). 330 ; Beck, hot. p. 84 ; Dariingt. fl. Cest. p. 413 ;

Stems 2-3 feet high, commonly several from one root, more or less hairy. 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 rigidum, DC. Rigid Desmodium. 



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

 ciliate, rough above, hairy underneath, tlie 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 ; Dariingt. fl. Cest. p. 413 ; Torr. ^ 

 Gr. fl. 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 calyx 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 Desmodium. 



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,
