 somewhat persistent. — L. gracilis, yitU.! in jour. acad. Pliilad. 7. p. 115,

Woodlands in liglit or sandy soil, Canada ! to the Southern States ! com- 

 mon. Also at Ca])c 3Iulgrave, Behring's Straits {Beechey) and Shores of 

 the Arctic Sea, Richardson, according to Hooker. 0. Fort Gratiot, Michigan, 

 Dr. Pitcher! y. South Carolina ! Georgia! and Alabama ! June. — Stem 

 erect, rather stout, striate, 1-2 feet high. Leaflets attenuate at the base. 

 Peduncle naked : raceme 4-10 inches long. Flowers large, showy, purplish- 

 blue. Bracteoles of the calyx very minute and caducous, or often wanting. 

 Legume very hirsute with appressed hairs. Seeds variegated. — Mr. Oakes 

 finds a white-flowered variety, and the same is mentioned by Mr. Curtis in 

 his Catalogue. We have never seen the plant of Dr. Richardson : if it truly 

 belong to this species, it forms the only instance within our knowledge of a 

 phenogamous plant indigenous to the shores of the Gulf of Mexico and of the 

 Arctic Sea ! The lower stipules of this species are frerpiently rather persis- 

 tent and wholly similar to those of L. gracilis, Nutt., of which we have also 

 more glabrous forms. — Common Wild Lvpine.

 in a loose elongated raceme ; bracts aboul the length of the pedicels, cadu- 

 cous ; calj'x minutely bracteolate ; the ujjper lip saccate or slightly spurred 

 at the base, minutely 2-toolhed a* the apex (entire, Agardh), the lower en- 

 tire ; keel naked or sliirhtly ciliate ; legumes silky ; 2-5 seeded. — Dougl. !
