Common Name The Arunachal Pradesh Gastrochilus

Flower Size .7" [1.8 cm]

Found in Arunachal Pradesh India and Myanmar in limestone forests on tree trunks or on rocks at elevations of 150 to 750 meters as a mini-miniature sized, hot to warm growing epiphyte with an erect stem carrying 3 to 4, nearly basal, distichous, oblong, slightly fleshy to leathery, obtuse to unequally bilobed leaves that blooms in the late summer and fall on 1 to 4, basal, peduncle straight, .4 to .8" [1 to 2 cm] long, stout, provided with 2 cupular bracts, sub-umbellate, 8 to 10 flowered inflorescence.

"Morphologically, G arunachalensis is closely related to G. pechei in having the sub-triangular epichile of lip and the hypochile of lip not laterally compressed. However, it can be easily distinguished from the latter by the small stature of plant with leaves less than 6" [15 cm] long, green or yellow green flowers, oblanceolate sepals and petals, and a triangular epichile without a central cushion.
