Type: Kempf s.n. (border between German and English New Guinea, Waria region) (holo B, lost)
Terrestrial, erect, up to more than 80 cm high. Rhizome and pseudobulbs not described. Leaves erect, narrowly lanceolate, acuminate, at the base gradually narrowed in the petiole, to 80 cm long, near the middle 2.2-2.4 cm wide. Inflorescence erect, straight or nearly so, slender, glabrous, more than 60-70 cm high, with a few, distant, tightly clasping, apiculate peduncle-scales, near the base c. 3 mm diam.; rachis rather laxly 6-12-flowered, short, to 10 cm long. Floral bracts pendent, oblong-lanceolate, acute, 3-4 times shorter than the slender pedicellate ovary. Flowers erect. Sepals elliptic, subobtuse, glabrous, c. 0.8 cm long. Lateral sepals oblique, a little broader than the median sepal. Petals broadly elliptic, obtuse, glabrous, almost as long as the sepals but broader. Lip deeply tripartite, c. 0.65 cm long, when flattened between at the tips of the lateral lobes 0.85 cm wide; lateral lobes divergent, at the base oblong, in apical half obliquely obovate-dilated; mid-lobe at the base broadly ligulate, very broadly obovate, minutely and obtusely apiculate, a little longer than the lateral lobes; basal callus double, fleshy, glabrous, near the base of the calli sparsely pilose, otherwise glabrous. Column slightly curved, semiterete, 0.7 cm long, glabrous. Ovary slender pedicellate, slender cylindrical, glabrous, c. 2.3 cm long. (After Schlechter, 1921)
