 There nro no very large-flowered species in ihis group, which approaches Odonto- 

 glossum nearly in 0. cimiciferum , etc. The leaihery lip remains characteristic , for 

 which reason I douht, whether 0. scansor can belong here.

This plont is very uiuch like 0, orgyale , and the figure of 0. undulatum in 

 ,.HBK,"; but I think ihey are rightly distinguished by Rchb., who has pointed out the 

 peculiarities of the crest. In this species it consisls of flve erect keels , of which 

 ihree are parallel, and in front of two which diverge almost at a right angle, in ad- 

 dition to which ihere are several lateral tubercles. The colours of ihe flower are 

 also different. According to Warscewicz, 0. orgyale has whole-coloured flowers with 

 brown sepals and deep violet lip , but 0. ventilabrum has cinnamon-brown sepals 

 and peials, with ihe upper half of ihe latter yellow, and a deep rose-coloured lip 

 yeliow al ihe basc.

 brown. wllh red bands in a dried state. The coiumn is abrupily bent back, and
