Bentham and Hooker retain four genera and estimate the number of species at 
scarcely thirty-five. In Solms-Laubach’s monograph, which appeared very shortly 
after the last volume of the ‘Genera Plantarum,’ Reussia, referred to Pontederia by 
Bentham ard Hooker, is regarded as a distinct genus ; but the total number of species 
described is only twenty-one. They are widely dispersed in warm countries, though 
most numerous in America, extending northward to Eastern Canada.

Pontederia, Linn. Gen. Plant. n. 399; Benth. et Hook. Gen. Plant. iii. p. 837. 
Solms distinguishes only two species of this genus and two of Reussia; all restricted
