This differs froni the plant, which was collected by Ridley on Thai- 

 ping Hills and named E. pellipes Rchb. f., by the broader acute petals 

 narrowed to the apex, the lip being denticulate in the upper portion, and 

 a differently shaped wholly glabrous anther, and from E. Jacobi>onii J. J. S, 

 especially by the very différent lip and anther. 



The flowers are yellow-green.
