and

Common Name Lyon's Epigeneium [English Trader and Orchid Enthusiast in the Philippines early 20th cen.]

Flower Size to 5" [to 12.5 cm]

Found in the mountains of Luzon, Philippines as a small sized, cold to warm growing epiphyte at elevations around 1600 meters with remote, obscurely angled pseudobulb that has a sharp apical tooth that is left after the deciduous elliptic or oblong, leaves fall that blooms on a terminal or subterminal, erect to arching, several to many [6 to 20], loosely flowered inflorescence that occcurs in the spring. Diagnostic to this species is the fact that, after leaf-fall, at the apex of the pseudobulb, will be a distinct tooth-like point.

This species is most likely E treacherianum but I have left them separate at this time just to be sure.
