Found in Thailand, penninsular Malaysia, Cambodia, Sumatra, Borneo and the Philippines from montane forests and in lowlands at elevations of 1300 to 2500 meters as a medium sized, cool to cold growing epiphyte with tall, thick, cylindrical stems carrying a few to 4, apical, lanceolate to strap-shaped, thin but tough, gradually narrowing below into the indistinct petiolate base leaves that can bloom at most any time but mostly in the summer with several, to 7.2" [18 cm] long, racemose, arching, densely many flowered inflorescence arising from the nodes near the apex of the stem
The three species, E floribunda, E densa and E pachystachya are often confused, I am sure that these three species are now correct on the site and each one match Seidenfaden's drawings exactly.
