Common Name The Eria-Like Flowered Dendrobium
Flower Size .4 to .6" [.9 to 1.5 cm]
Found in Assam India, Nepal, Sikkim, Bhutan, Myanmar, Laos and Malaysia at elevations of 800 to 2000 meters in primary and secondary broad-leaved evergreen and semideciduous forests of subtropical valleys as a small sized, warm to cool growing epiphyte on tree branches in bright light with clustered, fleshy at the base, attenuate above, yellow stems enveloped by loose sheaths and carrying up to 9, deciduous, oblong or lanceolate, obtuse leaves that blooms in the late summer and fall on a erect to arching, 1.6 to 3.2" [4 to 8 cm] long, laxly, several [6 to 8] flowered inflorescence with upside down flowers that open simultaneously.
Plants should be kept moist as they are growing but as they mature in the fall and winter sets in it is best to keep the watering and fertilizing at a minimum. Resume both water and fertilizer with the intitiation of new growth in the spring.
CAUTION I am not sure of these determinations. There are 3 distinct types here which may represent 3 different species. The first photo is Averyanov's determination. The third photo is closer to Hooker, King and Seidenfaden, the second is closer to Vadhanaphutti, Rajbhandari and Comber. No references make mention of the large anvil-like calli at the middle of the lip on the second photo. Seems it would be mentioned. So use with caution.
