and 
Common Name The Many Haired Habenaria
Flower Size 3 1/2" [9 cm]
Found in Thailand, Cambodia and Laos at elevations around 600 meters as a small sized, hot to warm growing terrestrial orchid with an erect stem carrying 2 to 5, cauline, scattered in the lower 2/3's of the stem, lanceolate, acute to acuminate, mucronate leaves grading above into 1 to 3, erect, lanceolate to ovate, acuminate, minutely denticulate to shortly hairy margined sterile bracts that blooms spring and summer on a glabrous, 7.6" to 16" [19 to 40 cm] long, lax, few flowered inflorescence with a 1.2" to 1.6" [3 to 4 cm] long, rachis carrying narrowly lanceolate, acuminate, margins sometimes shortly hairy leaves that needs a dry winter rest
This species seems awfully close to H medusa and if so then H medusa takes precedence. Kew has this one as a valid speciecs. I leave them together pending more research.
