somewhat longer and narrower than specified by the type 
description. The record of Reichenbach’s species shows 
a distinctly 8-lobed lip and the other perianth organs are 
the exact counterpart of those of Sarcoglottis pubilabia 
and Sarcoglottis zamororae. 
It appears that there is no justification for regarding 
Sarcoglottis zamororae as distinet from S.pubilabia tor 
the lips of both species show the presence of pilose hairs 
on the lower part of the disc in varying distinetness. The 
flowers of S. pubilabia appear to be somewhat smaller and 
are denser in the upper portion of the raceme than those 
of S.zamororae. 
The concept Sarcoglottis is preferred to Spiranthes 
because the lateral sepals are long-decurrent on the ovary 
unlike true Spiranthes, but they do not form a distinct 
spur as in the genus Pelexia.
