drawing. Dried specimens of young plants much resemble 
those of Pistia Stratiotes, Linn. The conspicuous yellow | 
flowers seated in the centre of the rosettes of bright 
green, red-edged leaves, render this plant highly decora- 
tive. 
The genus was named after the traveller, Hd. de 
Cadalvéene, author of a work entitled: L’Hgypte et La 
Nubie. Paris, 1836. | 
Our figure was taken from a plant which flowered in a 
stove at Kew in July last, having been grown from tubers 
received in 1903 from Mr. J. McClounie, Head of the 
Scientific Department, Zomba, British Central Africa.
