EARLY 
Common Name Dyer's Platanthera [Kew Director in later 1800's-early 1900's]
Flower Size .2" to .32" [5 to 8 mm]
Found in the eastern Himalayas and Bhutan at elevations around 3660 meters as a miniature to small sized, cold growing terrestrial with a thickly fusiform rhizome giving rise to an erect, slender stem with 1 or 2 basal overlapping, oblanceolate, obtuse sheaths and carrying 3 to 4, along the stem, sessile, oblong-lanceolate, subacute leaves that blooms in the early summer on an erect, terminal, .8 to 3.6" [2 to 9 cm] long, 5 to 8 flowered inflorescence with ovate-lanceolate, acute floral bracts.
"A very distinctive species with leaf-like floral bracts and gradually decrease in size upwards. The size and position of the very large stigma stgretching across the wide column almost to its edges and situated above the opening of the spur are good distinguishing charcteristics of this species." King & pantling 1898
Kew has this one as a synonym of P concinna and it may be but I have left them separate pending better references.
