Corymborchis cubensis usually occurs at much lower 
altitudes than C.flava. Both species are very similar in 
habit, being about the same height, and with coarse reed- 
like terete stems which are leafy above. Corymborchis 
cubensis has a grayish, usually lepidote peduncle ; whereas 
C. flava has a smooth, reddish, glossy peduncle. The ulti- 
mate branches of the inflorescence of C. cubensis are 
usually more in number than in C.flava, and are conspic- 
uously arcuate-descending ; whereas those of C,flava are 
fewer in number and are usually suberect or ascending. 
The flowers of C. cubensis are comparatively thin and 
delicate in contrast to the leathery and fleshy flowers of 
C flava.
