Basionym: Eria hapalostachys

Epiphytic, stout, probably pendent. Stems unbranched, terete, leafy, entirely covered with the densely puberulous, tightly clasping leaf-sheaths, 30-50 cm long, 0.5-0.65 cm diam. Leaves erect-patent, lanceolate-ligulate, acute, with slightly recurved margins, soon becoming almost glabrous above, very shortly and densely puberulous below, 12-14 cm long, below the middle 1.5-1.9 cm wide, fleshy-coriaceous. Inflorescence erect-patent, very shortly pedunculate, rather densely 10-18-flowered, to 8 cm long, densely stiff-hairy. Floral bracts slightly recurved, suborbicular, apiculate, usually a little longer than the ovary. Flowers recurved-patent, outside densely stiff-hairy. Sepals oblong-ligulate, subobtusely acuminate, 1 cm long. Lateral sepals oblique, at the base along the front margins strongly produced; mentum shortly cylindrical, towards the apex somewhat dilated, broadly obtuse, 0.5 cm long. Petals obliquely ligulate, subobtuse, above the middle a little dilated, sparsely pilose, a little shorter than the sepals. Lip above the narrow base gradually obovate-dilated, c. 1.2 cm long, above the middle 0.4 cm wide, in apical fourth abruptly expanded into a very broadly reniform, 0.6 cm wide blade, apex notched, minutely apiculate; keels 3, parallel, rather abruptly evanescent towards the base (the central keel a little longer). Column suberect, pilose; foot narrow, somewhat incurved. Ovary sessile, cylindrical-obconical, very densely stiff-hairy, 0.5 cm long. (After Schlechter, 1919)
