100. V. renifolia, Gray, (Proc. of Amer. Acad, of Arts and Sci., VIII.,

"Rhizome and flowers like V. blanda L. or the flowers a little 

 larger. Leaves reniform usually 5 cm. broad, both sides and the 

 petioles villous-pubescent, scape pubescent." Growing with V. 

 blanda and like it except its "reniform leaves are conspicuously 

 beset with pale, soft and tender, lax. hairs." Deep mossy swamps, 

 like the Round-Marshes and Mich. Hollow Sw. ; not uncommon. 

 The hairs are not as conspicuous, in our specimens, nor the scapes 

 or petioles as stout, as in northern specimens. We are probably 

 near the southern limit of the species.
