Flower Size .2" [5 mm]

Found in Thailand in seasonal evergreen forests and tropical rainforests within usually limestone rock crevasses at elevations of 50 to 800 meters as a miniature to small sized, hot to warm growing terrestrial with a tuber giving rise to a short stem carrying 3 to 5, in a basal rosette, large for the genus, light olive brown with dark brown reticulation above and light brown to dull olive green below, lanceolate, gradually narrowing below into the petiolate base leaves that blooms in the fall and again in the late winter and earlier spring on an erect, very thin, glandular-pubescent, 5 to 12" [12.5 to 30 cm] long peduncle, rachis to 3" [7.5 cm] long, 1 to 7 flowered inflorescence with an acuminate, shorter than the ovary floral bract.

Said to be a synonym of C spathulata and most likely is but I have kept them separate for now.
