We consider the interpretation of this species by Faw- 
cett and Rendle (Flora of Jamaica 1 (1910) 136, t. 30, 
figs. 26-80) to be correct. The lip (fig. 1) is essentially 
entire with only a slight dilation on each side above the 
middle or near the apex. The leaves (fig. 3) of D.echino- 
carpa are as a rule sufficiently different from those of D. 
muricata (fig. 4) to facilitate the separation of these often 
confused species. ‘The thin-herbaceous, elliptic-lanceolate 
leaves of D. echinocarpa taper to a long-apiculate to acu- 
minate apex, whereas the leaves of D.muricata are thick- 
subcoriaceous, ovate-elliptic to oblong-elliptic and round- 
ed and apiculate at the apex. 
Since it was originally described, this species has been 
confused with the invalid Limodorum pendulum Aubl. 
This confusion resulted from the citation by Swartz of 
Limodorum pendulum as a synonym of his Mpidendrum 
echinocarpon. Lindley perpetuated this error by citing 
Limodorum pendulum as a synonym when he made the 
combination, Dichaea echinocarpa. The invalidity of 
Limodorum pendulum is discussed later. 
This species is rare in Costa Rica; it is widespread but 
not common throughout the West Indies. It is found 
on trees and shaded rocks in forest, and grows up to 2400 
meters altitude in Costa Rica.
