Another Flower? Plant seems wrong

Drawing Drawing by Seidenfaden


Common Name The Goat-Horned Cleisostoma [refers to the strongly recurved leaves, a diagnostic character]

Flower Size 3/8" [8 mm]

Found in Thailand and Myanmar on karst limestone hills at elevations around 550 meters as a mini-miniature sized, monopodial, hot to warm growing epiphyte occuring on stunted trees or as a lithophyte on the limestone beneath with a freely branching stem enveloped by imbricating old leaf sheaths carrying towards the apex, distichous, terete, strongly recurved [goat horn like], basally grooved leaves that blooms in the summer on an axillary, horizontal to suberect, unbranched, [21 to 55 cm] long, to 20 flowered inflorescence with ovate, acute floral bracts and up to 5 flowers open at any one time.

The leaf shape [crucial] cannot be seen well in the first photo and the photo is not good enough for an exact determination but this represents the closest I can find to the real C capricorne. I await more photos to be certain. The second photo by Pfahl has the flower shape but the leaves are wrong. The Drawing most likely is correct.
