This grows on trees, often low down. It seems to be most 
nearly allied to EZ. polystachya, A. Rich., but is quite glabrous, 
and the racemes are produced from below the leaves. The 
flowers are of a remarkably thin texture, very troublesome to 
examine after drying.

I have only seen one specimen of this, and that dried. It 
belonys to the section with a stout stem covered with large 
sheaths, from the axils of which the racemes arise. The few 
distant flowers, and the distinctly three-lobed lip, and very 
short mentum, are peculiar.
