2n = 40

Plant at fl. to 100 cm. long, us. less. Stem us. drooping, completely clad in sheathing lf-bases. Lf-sheaths c. 2–3 mm. diam., not split, forming tube-in-tube structure, each covering the lower third to half of the one above and flattened in the plane of the ± distichous lvs, the exposed surfaces pale with small dark spots; lamina 6–15–(20) cm. × 4–6 mm., widest near base and tapering very gradually to acute, minutely acicular tip, soon falling and leaving lower half of stem with lf-sheaths only. Rhizome slender, pale except for dark nodes. Panicle to c. 10 cm. long, drooping; racemes 2–6–(10), well spaced on very slender axis, each 3–4 cm. long; floral bracts c. 4 mm. long, barely overlapping, longitudinally ridged, hiding short pedicel. Per. c. 10–12 mm. diam., opening widely, pale, slightly greenish cream. Sepals elliptic, subacute. Petals slightly broader and more obtuse. Labellum much broader and more showy, yellowish to apricot, spreading widely in fl., broadly oblong in overall outline, broad proximal part connected by narrow isthmus with almost equally large distal lobe; near base 2 inconspicuous ridges lead down to small pit (nectary?). Column much shorter, narrow to base, wings obsolete; pollinia long-oval.
