its mostly simply pirate bran* lies diffusely, occurring near 

 the roots of trees, that are often under water and mi vrei 

 rocks, in (louse tufts. The uATEs are unc;' imbricate, 

 often a little distant, and generally alternate, obliquely 

 ovate, (resembling in shape an car,) undulated slightly in 

 the margin, and, when dry, much inflected. The stipu- 

 lae are small, roundish, the middle one much larger than 

 the two lateral ones ; obliquely arranged, and so distant, 

 that the naked caulis appears between the pairs or threes. 

 Calyx distichous, imbricate, stipitate, compressedly cylin 

 drical.

Common here, particularly in the ripples of brooks, 

 floating. The color of the broad leaves is a blackish blue : 

 they are thin and flat. Dv. Torrey has sent me speci- 

 mens, although it is not in New-York catalogue. 



The calyx and seta are said by Dickson to be as in the 

 former ones. No botanist, except he and Dillenius, has 

 however seen them. With us it is always sterile.
