Type: Cock d'Armandville, le 242

Stems in cross-section elliptic, becoming branched with age, leafy, part examined 12 cm long, internodes 0.7-0.8 cm long, 0.2 cm wide. Leaves patent, narrowly lanceolate, 3.35-4 by 0.65-0.7 cm, above and underneath sparsely furfuraceous-punctate, thinly coriaceous, gradually narrowed towards the apex, at the apex conduplicate and somewhat unequally or almost equally minutely obtusely 2-lobulate, the whole margin irregularly erose, mid-rib grooved above, slightly prominent below; sheaths longer than the internodes, tubular, in cross-section elliptic, 0.25 cm wide, in front especially towards apex finely warty, sparsely furfuraceous-punctate, opposite the blade with an obtuse tooth. Inflorescence capitate, nodding, c. 9-flowered, subtended by 1-2 large, strongly concave-cucullate, partly acuminate, sparsely furfuraceous-punctate sheaths. Floral bracts large, orbicular-elliptic or subovate, obtuse or slightly acuminate, cucullate, 3-nerved, membranous, 0.8-1.1 cm long, 0.6-0.85 cm wide. Flowers 1.1 cm long. Median sepal ovate-elliptic, 0.68 by 0.38 cm, at the apex recurved, obtuse, dorsally near the apex with a laterally compressed thickening, at the base for 0.18 cm adnate to the lateral sepals, in the basal part concave, 3-nerved. Lateral sepals in front highly connate, half-clasping the ovary and wholly enveloping the spur of the lip, free part obliquely ovate-triangular, obtuse, apiculate, at the back 0.3 cm., in front 0.53 cm long, 0.48 cm wide; mentum pointing backwards, saccate, broadly obtuse, at the apex on either side concave-sunken, at the base with two convex inflated parts, 0.35 cm long, slightly over 0.4 cm wide. Petals subrhombic-oblong, obtuse, 3-nerved, 0.63 by 0.28 cm. Lip at the base shortly adnate to the column, to the apex of the ovary 0.3 cm long, to the apex of the spur 0.6 cm long, blade recurved, porrect, concave, when flattened transversely rectangular, truncate, underneath obtusely apiculate, base abruptly thickened, 0.23 by 0.63 cm; spur making an acute angle with the ovary, oblong, obtuse, dorsally near the base with a conspicuous, deeply concave dent, 0.43 cm long. Column dorsally convex, at the apex broadly triangular, obtuse, 0.25 cm long, at the base for 0.1 cm adnate to the lip. Anther cucullate, transversely elliptic, 0.15 cm wide, connective gibbose. Rostellum prominent, broad, truncate. Stigma orbicular, with the lower margin strongly dilated but much shorter than the rostellum. Ovary 6-grooved, including the short and thinner pedicel 0.5 cm long. (After Smith, 1915).
