Common Name Treacher's Epigeneium [Colonial Secretary of Labuan [Island near Borneo] 1800's]

Flower Size 1 1/4 to 3 1/5" [3 to 8 cm]

Found in Borneo high in primary forests in the canopy of large rough barked trees on large branches at elevations of 100 to 400 meters and needs high humidity and bright light. It is a small sized, hot to warm growing epiphyte with a stout rhizome with crowded, ovoid, 4 to 6 angled, dull brownish green pseudobulbs carrying 2, stiff, oblong-elliptic to narrowly elliptic, retuse, leathery leaves and blooms on a terminal, porrect to pendant, 4 to 6" [10 to 15 cm] long, few to several [2 to 7] flowered, racemose inflorescence with fragrant [dried coconut], resupinate flowers occuring in the summer. E lyonii is said to be a synonym of this species and is found in the Philippines, I have left it separate at this time, until I can have both species available to me at the same time.
