 jointed ; joints triangular, hispid. Hedysarum canescens Linn. H. 

 scaberrimum Ell. ? 



HAB. Dry woods. Can. to Car. June Aug. !. Stem 34 

 feet high, and more scabrous than any other American species. 

 Flotcers pale purple, middle-sized. 



3. D. marylandicum De Cand. : stem erect, pilose, branching ; 

 leaves ternate ; leafets oblong, villous beneath ; stipules subulate ; 

 racemes paniculate ; legumes 3-jointed ; joints rhomboidal, reticulate, 

 somewhat hairy. H. marylandicum Linn.

 Stem hairy above. Flowers purple, in a somewhat loose and 

 slender panicle. 



4. D. obtusum De Cand. : stem erect or ascending, pubescent; leaves 

 ternate; leafets ovate, obtuse, subcordate at base ; stipules lanceolate- 

 subulate ; panicle terminal ; joints of the legume semi-orbiculate, retic- 

 ulate, hispid. H. obtusum NnliL in 11 "illd. 



HAB. Woods. N. Y. to Car. July, Aug. L. Stew 23 feet 

 high, sometimes cespitose. Flowers purple, in a terminal pani-

 obtuse, scabrous on the upper surface, villous and very soft beneath; 

 panicle terminal, very long, naked ; joints of the legume triangular. 

 Hedysarum riridiflorum Linn. Ell. Torr. not of Pursh.

 very scabrous towards the summit. Leares very scabrous on the 

 upper surface, clothed with a velvet-like tomentum on the under. 

 Flowers purple within, greenish without. This is undoubtedly 

 the true H. viridifontm of Linnaeus ; a plant which seems to be 

 quite distinct from the next. See Ell. Sk. ii. 217.

 ternate; leafets ovate-oblong and sub-deltoid, acute, mucronate, sca-

 Hedysarum riridiflorum Pursh. H. aikini Eat. 



HAB. Woods and old fields. N. Y. Penn. July, Aug. It. 

 Stem 3 feet high. Flowers reddish-purple, becoming green when 

 dry. This plant differs from the true H. viridiflorum in the 

 leaves being very scabrous beneath, and was very properly se- 

 parated by Prof. Eaton in the last edition of his Manual of 

 Botany. 



7. D. ciliare De Cand. : stem erect, branching, pubescent ; leaves 

 ternate, on short petioles ; leafets small, oval-obtuse, pubescent under-
