Discusión taxonómica
(In relation to the synonym Terpsichore mollissima) None of the Mexican and Central America specimens identified as T. mollissima in herbaria matches type material seen, and it may be that continental specimens are specifically different from those of the Lesser Antilles. For the present, we maintain usage of the name in its traditional application.
Generally, T. mollissima occurs at lower elevations than allied species (T. cultrata, T. senilis). The lack of rhizome scales distinguishes T. mollissima from small forms of T. cultrata (q.v.). Terpsichore alfarii (Donn. Sm.) A. R. Sm. of southern Central America also lacks rhizome scales, but has a conspicuous hump along the acroscopic margin of each segment.
Mickel 5561a (NY), cited by Mickel and Beitel (1988) as this species, is T. cultrata.A
