Leaf sheaths shorter and/or longer than the internodes, glabrous; blades 10-60 x 0.2-0.5 cm, base straight, linear, conduplicate
or flat, glabrous on both surfaces or scabrous-pubescent on adaxial surface, apex acute or subobtuse; ligule 1-1.4 mm long, membranous ciliate.
Leaf erect-arching, chartaceous, light green, narrowly elliptic, obtuse, oblique and emarginated at apex, 4.7-10 x 1-1.2 cm; the base sub-petiolate and conduplicate
. Inflorescence lateral, developing from the base of the upper sheaths of the pseudobulb, 1-2 per pseudobulb and flowering season, longer than the leaf, arching, 10-13 cm long, apparently racemose but rather a panicle since it presents very short branches measuring 3 mm long; peduncle erect, cylindrical, as long as the leaf, 6 cm long, at the base with a tubular bract 3-5 mm long; rachis 7.5-8 cm long, bearing 8-12 flowers which open successively.
2 mm long, base sagittate, apex acute and apiculate, dorsifixed at 1/3 of its length above the base; stigma conduplicate
6 mm, the antesepalous ones 11-12 mm long, free; anthers 1.7- 2 mm long, base and apex obtuse, compressed laterally, green, dorsifixed at middle; pollen sulcate, ellipsoid, exine reticulate, muri narrowed; stigma conduplicate
1 mm in diameter; stigma conduplicate
, lobes erect, slightly if at all twisted, ca.
2.5 mm long, dorsifixed near the base, base sagittate, apex obtuse; pollen broadly ellipsoidal, sulcate, exine microreticulate, lumina irregularly polygonal; ovary 6-7 x 3-4 mm, subtrigonous, greenish-white, glabrous or nearly so; epigynous tube lacking; placentation apical or nearly so; ovules numerous, globose, obtuse; style slightly exceeding the anthers; stigma conduplicate
, white, the styler lobes terete, suberect, ca.
24 mm; stamens completely exposed by the recurved petals at anthesis, radially disposed; filaments terete, white, the antesepalous ones free, the antepetalous ones shortly adnate to the petals; Anthers linear, 13-15 mm long, base sagittate, apex obtuse, fixed near the base, slightly shorter than the petals; Pollen narrowly ellipsoid, sulcate, exine reticulate, lumina rounded, muri slightly thickened; style exceeding the petals, white; stigma conduplicate
, blades spreading-contorted, densely papillose, white, ca.
