Trichotosia gjellerupii W.Kittr., Bot. Mus. Leafl. 30 (1984, publ. 1985) 98 (as nom. nov.)

Basionym: Eria integra

Stems close together, elongated, terete, in the basal part with appressed red-brown hairs, in the upper part glabrous, only appressed hairy at the nodes, to c. 95 cm long, leafy, internodes 1.4-3.5 cm long. Leaves patent, narrowly lanceolate, at the apex gradually strongly obliquely acuminate, tip narrowly obtuse, at the base conduplicate, the young leaves pilose underneath, mature leaves more or less glabrous, when dried coriaceous, 6.5-11 by 1-1.5 cm; sheaths tubular, as long as the internodes or longer, appressed hairy, especially towards apex on the side apposite the leaf-blade, otherwise more or less glabrous. Inflorescences arising from the internodes of the leafy stems, puncturing 1 or 2 sheaths, hairy, laxly 8-13-flowered, 6-10 cm long; peduncle 1.5-2.2 cm long; peduncle-scales few, basal, small, obliquely funnel-shaped, broadly obtuse, becoming larger away from the base, to 0.6-0.8 cm long, clasping the peduncle; rachis zigzag. Floral bracts widely patent or more or less reflexed, rather large, ovate, narrowly obtuse, concave, dorsally hairy, becoming smaller towards the top of the inflorescence, 0.85-1.3 cm long, 0.38-0.95 cm wide, the lowers ones orbicular, 0.9-1.1 cm long and wide. Flowers rather small, 1 cm wide. Sepals dorsally covered with long and patent hairs. Median sepal oblong, obtuse, obtusely conical-apiculate, concave, 3-nerved, 0.64 by 0.24 cm. Lateral sepals triangular, obtuse, dorsally near the apex long subulate-horn-shaped, concave, 5-nerved, 0.66 by 0.4 cm; mentum short, pointing backwards, making an acute angle with the ovary, truncate, 0.2 cm long. Petals linear-oblong, slightly falcate, obtuse, concave, 3-nerved, glabrous, 0.55 by 0.16 cm. Lip erect, strongly recurved, almost entire, with very indistinct lateral lobes, concave, without keels, 3-nerved, somewhat fleshy, when not flattened 0.37 cm long, when flattened obovate, at the base truncate, 0.53 cm long, epichile (mid-lobe) recurved, crenate-undulate, inside papillose, when flattened angular-semiorbicular, broadly obtuse, very shortly obtusely apiculate, 0.18 by 0.33 cm. Column straight, dorsally convex, 0.25 cm long, at the apex rounded, below the stigma puberulous; clinandrium suborbicular, concave, auricles rounded, slightly crenate; stigma transversely elliptic; column-foot making an acute angle with the ovary, subquadrangular, truncate, with a longitudinal groove, puberulous, 0.17 cm long, almost 0.2 cm wide. Anther cucullate, rounded in front, 0.1 cm wide. Ovary sessile, short, 6-grooved, hairy, 0.38 cm long. (After Smith, 1913)
