A very pretty water-plant of wide distribution, inhabiting 
very wet marshes from Virginia to Venezuela and Brazil, and 
likely to become a favourite for cultivation in tropical aquaria, 
where it may be grown in pots standing in the water. As 
far as I am aware, but one species of the genus Heteranthera 
had hitherto been cultivated in Europe, namely the i 
grammea of Vahl, a very insignificant submerged species, a 
native of North America, which was introduced into the 
Glasgow Botanical Garden half a century ago, along with 
Vallisnerea spiralis, and is well figured in Hooker’s “ Exotic 
Flora,” tab. 94, under the generic name of Leptanthus. About 
a dozen species of the genus are described, some of which, 
_—- spikes of blue flowers, are no doubt worthy of cultiva- 
ion, 
Seeds of H. limosa were sent from Santa Martha, in New 
Grenada, to the Royal Gardens by M. Endres, which ger- 
minated and flowered in the short space of a few weeks. M. 
Endres states that it grew in brackish pools. It flowers at 
Kew from May onwards. It isa plant of very wide range,
