VANILLA. 



Swartz founded this genus, embracing about a score 

 species of sto\-e climbing Orchids belonging to the tribe 

 Ncotticic. The species are scattered over the tropical 

 regions. They are rarely cultivated in Orchid collections. 

 Flowers large but usually dull-coloured and uninteresting, 

 in short spikes; sepals and petals sub-equal, free, spreading; 

 claw of the lip adnate with the elongated wingless column; 

 the limb broad, concave, its base rolled round the column ; 

 bracts ovate. Capsule often elongated, fleshy. ]\inilla is 

 remarkable for being the only genus of the Order that 

 possesses any economic value, the fruits of several of the 

 species being used for flavouring purposes. The species 

 should be grown in large pots or planted out in beds, in 

 a compost of fibrous loam, leaf-soil, peat, and sphagnum, 

 with plenty of sand intermixed. The generic name is 

 from the Spanish vainilla, a little sheath ; in allusion to 

 the shape of the fruit.
