Discussion

Lepanthopsis melanantha is recognized by its small stature and shoots with ciliate sheaths with dilated mouths; a relatively short, distichous raceme of few or several, simultaneous, dark red-purple flowers, usually surpassing the leaf; and a broadly ovate, concave, dorsal sepal, with oblong lateral sepals connate proximal to the middle, minute petals, and a broadly cordate, obtuse lip with a smooth, shallow depression at the base. It is known in the flora area only from the Fahkahatchee Swamp in Collier County, Florida.
