Type: Janowsky 318 (holo BO)

Synonyms:

Epiphyte, very small. Rhizome very short, pendulous, the apex ascending, c. 2.75 cm long, covered with rather large, subulate-apiculate sheaths. Pseudobulbs close together, subcylindric, in front channelled, 0.6-0.65 by 0.16-0.26 cm. Leaf linear-lanceolate, obtuse, laterally compressed-apiculate, convex, fleshy, in total c. 2.4-4.2 by 0.5-0.37 cm; base long contracted in a conduplicate-channelled petiole, above on either side of the longitudinal groove convex, groove obtusely angled; petiole 0.4-0.7 cm long. Inflorescences 1-flowered, from the base of the pseudobulbs, short; peduncle short, covered with a few small, each other laxly clasping, in the basal part tubular, acuminate, acute, keeled, enlarging, to 0.46 cm long peduncle-scales. Floral bract very small. Flower very small, widely opening, 0.73 cm wide. Median sepal erect, oblong-ovate, conical-apiculate, concave, 3-nerved, 0.36 by 0.16 cm. Lateral sepals widely patent, obliquely ovate-triangular, shortly conical-apiculate, convex, 3-nerved, 0.37 by almost 0.2 cm; apex somewhat concave. Petals very small, porrect, parallel, appressed to the column, linear, acute, finely ciliate, convex, 1-nerved, 0.15 by 0.03 cm; apex slightly falcate-incurved. Lip submobile, porrect, 0.4 by 0.07 cm high; claw quadrangular, concave, 3-nerved, margins above incurved, below the apex of the column-foot inserted, fleshy, laterally compressed; above the base with 2 very small, reversed, subtriangular, parallel, slightly incurved, obtuse auricles distinctly shorter than the claw, the upper margin at the back extended in 2 backwards pointing, horizontal, slightly curved, upwards semiorbicular, somewhat fleshy short auricles; in lateral view narrowly obliquely oblong, in front somewhat higher, lower margin above rounded; apex slightly incurved, subobtuse, upper side slightly below the apex with c. 3 reversed seti; upper margin in the upper third of the lip slightly obtusely angled, dilated, largely verruculose-papillose. Column near the middle obtusely angled, recurved, oblong, in the basal part dorsally compressed, 0.13 cm long, the apex broadly obtuse; clinandrium concave; stelidia hardly longer than the anther, porrect, parallel, triangular, somewhat acute, lower margin obtusely angled.; stigma quadrangular, almost as wide as the column.; column-foot almost with a straight angle to the ovary, making an obtuse angle with the column, rather thick, linear-oblong, straight, the apex free, obtusely angled, incurved, rounded and underneath sloping down, in front convex, to the apex of the ovary 0.08 cm long, to base of the column slightly over 0.1 cm long. Anther cucullate, suborbicular, 0.03 cm wide; connective thickened; apex elongated, apiculate. Pollinia 4, oblong-pear-shaped, outside convex, inner ones smaller than the outer ones and thinner textured. Ovary 6-grooved, 0.08 cm long; pedicel 0.28 cm long. (After Smith, 1916)
