708 ORCIilDES. 



ONCIDIUM. 



resting by their points od broader ones in front. Column slender, with minute ligu- 

 late wings , lacerated at the drooping points , and placed on the lower cdge of the 

 stigma. In ihe single flower I examined I only found a pair of thick deep wrinkled 

 iamellae in the middle of the lip, which is very fleshy and convex except at the edge. 

 The lozenge-form only appears upon llatiening the base.

Trockene BJuthen hellbraun mit rothen Querbinden. lch weiss nicht, dass irgend 

 eine Art dieser Abtheilung eine so merkwurdige Verbindung der Saule und Lippe 

 habe. Angebahnt ist sie bei mehren Cyrtochila und Basilata , indem eine wulstige 

 Vermitilung zwischen Lippe und Sanle Statt hat, und ich betrachte diess Moraent als 

 Fingerzeig, dass ich es mit einem Cyrtochilum und keinem Odontoglossum zu thun 

 babe. Neu-Granada. Purdie.

 in ligulam longam producto. carina antice rostrata. bisulcaia in disco. utrinque tuber- 

 culatii. Jinea lunaia carinata sulcis transversis quodnmmodo polyodonta (sed retusa —

 favoured me corres[>onds with tliis. Tlie lateral sepals are represented as linear- 

 lanceolaip, verv wavy , and coiinate at ihc base ; which separaies the plant from any 

 form of 0. halieratiim.
