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

 unexpanded flowers and filaments of tlie stamina thickly 

 covered with round, blackish, glandular? atoms; tube 

 perforated with 3 g-ashes. 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. The P. limosa belongs 

 to the genus Heteranthera, having a capsule of 3 ceils, a 

 character very erroneously retained to Pontederia in which 

 there is no capsule at all.

Probably not exactly a congener with the New Holland

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

 gose, persistent. Stamina inserted upon the 

 margin of the orifice. Style triquetrous, tri- 

 partile. Capsule semisuperior, 3-celled, many-

Root preemorse, tuberous, bitter; leaves radical, dis- 

 posed in a stellate rosette; scapes simple; flowers spiked. 

 (Capsule opening horizontally all round?t seeds minute, 

 subcylindric.) 



"i" I am not satisfactorily acquainted with the mode by which 

 the capsule opens; it certainly does not open above, the sum- 

 mit being firmly closed and indurated.
