Caulescent herbs with a chain of corms. Leaf solitary terminating the corm, 

 decaying before the lateral scaly stem arises. Flowers few in a terminal raceme. 

 Perianth brownish yellow, mixed with purple. Lateral sepals narrow, slightly curved.

Epiphytic herbs. Leaves borne on a short club-like pseudobulb, from the base of 

 which arises the lateral flower-stalk. Flowers in a terminal panicle. Perianth mainly 

 brown or yellowish. Lateral sepals relatively broad. Petals longer than the sepals. 

 Lip wider than long, the lateral lobes larger than the middle one, the claw jointed to 

 the slender column-foot. Capsules drooping, 



1. Cyrtopodium punct^tum (L.) Lindl. Pseudobulbs 1.5-4 dm. long: leaf- 

 blades broadly linear-attenuate, 3-7 dm. long: flower-stalks 8-15 dm. long: perianth
