Madagascar, Imerina, Deans Cowan (icon.), Lyalll Serb. Kew. 



This is a very lingular plant, with a stout stem covered with 

 sheathing-leaves, and terminated by a short loose spike of about 

 five flowers. The dorsal sepal is lanceolate, with the edges in- 

 flected so as to be somewhat hooded. The petals are bifid, both 

 the lobes are very narrow, aud the lower one is much longer 

 than the other and directed forward. The lateral sepals are 

 oblong obcuneate, with the upper angle acute. The lip has a 

 short oval-triangular base, and three long, very narrow lobes, 

 the middle one of which is the longest. The spur is twice as long 

 as the ovary, irregularly bent, and thickened at the apex. The 

 whole flower is green, except the anther, which is cinnamon- 

 coloured, and exhales a perfume of vanilla. The auther-lobes 

 are slender, long, and straight ; the stigmatic arms shorter, thick, 

 and blunt. 



The description is taken from the original specimen in Herb. 

 Kew, and a very excellent drawing, with details, by Deans 

 Cowan, in the British Museum Herbarium.
