Inflorescence Photos by © John Varigos
LATE 
Common Name Floriferous Eria - In China Ni Mao Lan
Flower Size 1/4" [55 mm]
Found in Myanmar, penninsular Thailand, Vietnam, Malaysian penninsula, Sumatra, Java, Borneo and the Philippines in primary montane forests as a small to medium sized, warm to cold growing epiphyte on large trees along streams at elevations of 500 to 2400 meters with erect, stem-like, narrowly ellipsoid pseudobulbs carrying 2 to 5, apical, linear-lanceolate to elliptic, acute, soft leaves that blooms in the spring on an axillary, 8" [20 cm] long, densely many flowered, racemose inflorescence that arise, several at a time, from the nodes on the upper half of the pseudobulb.
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.
Plant in a pot with medium fine bark and treefern mix and give bright shade with a regular weekly fertilizing while growing and a lessening when not.
