Echinosepala
Echinosepala is a proposed genus of orchids comprising the subgenera Silenia and Satyria of the genus Myoxanthus. There is little reason to resist this change, thus Echinosepala is widely accepted. The genus contains 8 species.
The genus was formerly known as Echinella Pridgeon & M.W.Chase, but as this latter also refers to an algae genus, it has been changed to Echinosepala.
