The Lycaste leucantha was discovered by J. de Warscewicz in 
Costa Rica. It has flowered since in many continental gardens. 
It would appear to have been sent recently to England. We 
obtained it in Hamburgh Botanical Garden from Mr. Carmiol, 
one of whose plants is just flowering (Jan. 1869). 
Adventitious roots filiform, hairy towards the point, usually 
subterraneous. Sheaths beneath the pseudobulbs three to four, 
seldom only two, triangular, soon scariose, imbricate in the young 
shoots. Pseudobulb compressed, pyriform, bluntly two-angled, at 
length with two to five blunt ribs on each side, quite smooth
