the tube, upper lip marked with a broad g-reenlsh spot, 

 unexpanded flowers arid filaments of the stamina thickly- 

 covered with round, blackish, glandular? atoms; tube 

 perforated with 3 gashes. Three. lower stamina some- 

 times longer than the corolla. 



Of this singular genus of aquatics there are 3 species 

 in India and 2 in tropical America. I'he P. Umosa belongs 

 to the genus Heterantheva, having a capsule ot" 3 cells, a 

 character very erroneously retained to Pontederia in which, 

 there is no capsule at all. 



fit Flowers naked.

Corolla tubulous, ovate, summit 6-cleft, ru-

■\ I am not satisfactorily acquainted with the mode by which
