 Herb. Brit. Mus. 



A very handsome plant belonging to the spurless group, and 

 remarkable for the shortness of the lip. The leaves are a foot 

 long by 3 inches broad, gradually tapering to the base ; the stems 

 bear racemes of about 13 flowers. The sepals and petals are 

 rose-pink ; the lateral lobes of the labellum are yellow with pink 

 spots, the middle lobe pink with a yellow centre ; the callus, 

 which consists of two slightly curved diverging horns, is yellow ; 

 in front of it lies a patch of yellow hairs ; the column is also 

 yellow and the bracts brown. 



The plant was introduced into cultivation by Leon Humblot.

EtJLOPHIA. 



This genus, which is most abundant in the Cape and tropical 

 Africa, extending also to India and Malaya, is very well repre- 

 sented in Madagascar. 



All the Madagascar species known to me belong to the section 

 Genuine, in which the flowering scape is leafless, i. e. bears only 

 sheathing-leaves, and springs from the side of the leaf-bearing 

 pseudobulb. In most the leaves appear not to attain their full 

 development till after flowering. In one species, E. beravensis, 

 Eeichb. f., the leaves are borne at the top of a tall stiff stem, naked 

 except for a few sheathing-leaves. Most of the species are 

 terrestrial, but at least one is epiphytic. Out of the nine species 

 all but one, a native also of Mauritius, are endemic. The flowers 

 are usually yellow, plain or variously marked.
