Kichornia is a genus of South American, especially Brazilian, 
aquatics, separated by Kunth from Pontederia, and of which our 
Pontederia azurea, Bot. Mag. t. 2932 (now Lichornia speciosa), 
is a very interesting representative, partly owing to the size and 
beauty of the flowers, and partly from its floating habit and the 
power of buoyancy in consequence of the swollen leaf-stalks filled 
with air-cells. The blossoming of that plant is however of very 
rare occurrence; whereas our present species (for the introduc- 
tion of which we are indebted to James Wetheral, Esq., late of 
DECEMBER lst, 1857.
