 Rouxd-leaved DEs:vroi)iu>r. 



J?<k>* perennial. S/em 2 to 4 feet long, slender, trailing, somewhat branched, 

 angular, hirsute with spreading hairs. Leaflets nearly orbicular, 1 to 2 and a half 

 inches in diameter, thin, pilose with appressed hairs on both sides, ciliate on the 

 margin, somewhat glaucous beneath, the terminal one larger, rhomboid-orbicular ; 

 common petioles 1 to near 3 inches long, sulcate-striate, hairy ; stipules obliquely 

 ovate, acuminate, nerved, hairy and ciliate, persistent, mostly reflexed. Floieers 

 in axillary pedunculate racemes, also in a loose slender terminal panicle ; pedi- 

 cels about half an inch long, pubescent; lower bract cordate, acuminate, nerved, 

 ciliate. Calyx smoothish; segments lanceolate, acute, the lower one prolonged^ 

 —or sometimes the segments ovate, nearly equal, densely ciliate. Corolla bright 

 purple, with tinges of violet. Legume subsessile, of 3 to 5 subrhomboid tenaciously 

 hispid joints. 

 Uab. Hilly? rocky woodlands : frequent. Fl. August. Fi\ September—October. 



Obs. This is the canescens, of Willd. according to Muhlenberg,— who, it may 

 be presumed, wa3 correctly informed on that head ; and I apprehend the circum- 

 stance has led several subsequent Botanists to confound it (or at least the descrip- 

 tion of it) with the true cantsccyis, of Linnceus. Eight or tau additional species are 

 enumerated in the U. States ; and probably others remain to be detected. They 

 require to be all brought together, and compared, in order to have them determ- 

 ined accurately. As Prof. I)e Candolle remarks, it is a " genus viatoribus mono* 

 graphis'jue ralde* commendu)idum."

 [Dedicated, by Michaux, to Governor Lespcdez, of Florida.] 



Calyx bibracteatc at base, 5-parted ; segments nearly equal, lance-lin- 

 ear, or subulate. Keel obtuse. Legume lenticular, unarmed, 1-sced-

 ones wanting ; jloivcrs racemose, or spiked ; pedicels mostly in pairs, 

 with 3 nearly equal bracts at base. 



1. L. reticulata, Pers. Stem erect, subsimple ; leaflets narrow, 



oblong-linear, obtuse, mucronate, reticulately veined, hairy beneath ; 



racemes numerous, subumbcllatc, axillary, subsessile ; legumes ovate, 



acute, or acuminate, reticulate, longer than the calyx. Becky Bot. p.
