The genera Heter anther a of Pai.isot de Beauvois. 
and Leptanthus of Michaux, are perfectly synonymous, and 
considered by all authors as having, besides other characters, 
a capsule of three cells. The present individual having onl) 
one cell, Wili.denoav thought proper to construct a ne\\ 
genus for it, which he denominated Schollera. It appears tc 
me, however, that, by modifying the character of the genuf 
Leptanthus, it may with propriety be allowed to remain as pe- 
culiar to this species, the remaining Leptanthi of Michaux 
being retained in the older established genus Heteranthera 
Besides the more important character of the capsule, our Lep- 
tanthus seems to differ remarkably in habit, and in the coloui 
of its flowers, from the other individuals that have been ar- 
ranged with it. 
This plant is a native of Pennsylvania and Virginia, ac- 
cording to PuRSH. Mr MuRUAY of our Botanic Garden be- 
ing desirous to introduce the curious %lisneria spiralis to ouj 
collections from Canada, wrote to his correspondent Mr Kippi> 
at Montreal, to request he would send some of the mud con- 
taining roots and seeds of that curious vegetable. Along witl 
the Valisneria, there came up abundance of Najas canadensis 
and Leptanthus gramineus; the latter, alone, however, has a1 
present produced flowers and seeds. 
The plant grows entirely submerged, and has a striking re- 
semblance, when out of flower, to the Potamogeton granii- 
neum.
