Type: Jongejan cult. 1236 (holo L, spirit only)

Rhizome pendulous perpendicularly, to 70 cm long; flattened and winged, large, diam. 0.08-0.15 cm Rhizome portion between two pseudobulbs usually without a node approximately half-way, sometimes with a node at approximately 2/3 of its length. Rhizome scales of the longest internodes distinctly shorter than those internodes, leaving bare large portions of the rhizome. Roots generally close to the base of the rhizome. Pseudobulbs cylindrical, 1.2-3.5 cm apart, 0.1-0.35 by 0.08-0.15 cm, not flattened. Petiole 0.8-1.5 mm. Leaf blade ovate to elliptic; base often cordate, 0.8-2.5 by 0.7-2.2 cm, index 1.1-2; tip acuminate. Inflorescence 3.5-5 cm, 1-3-flowered; peduncle 0.5-2 cm. Floral bracts c. 3. the longest 0.35-0.5 cm. Rachis 0.2-0.6 cm. Floral bracts triangular, 2.8-4 mm; tip acuminate. Pedicel and ovary 4.5-7 mm, with the node 0.13-0.2 cm from the floral bract. Flowers all open time, moderately opening. Median sepal ovate, 22-28 by 3 mm, index 7-10; tip long acuminate to caudate, thin, glabrous. Lateral sepals free, oblique, triangular, 22-28 by 3-3.5 mm, index 7-10. otherwise as the median sepal. Petals elliptic, 3-4 by 1.8-2.5 mm, index 1.6-2; tip acute, thin, glabrous. Lip curved, general outline ovate, in lateral view highest near the base, 0.35-0.45 by 0.18-0.2 cm, index 1.6-2 (not spread); tip obtuse, thick but soft, glabrous; adaxially concave near the base; abaxially with an inconspicuously, retuse median ridge. Column from ovary to the tip of the stelidia 1-1.3 mm; stigma protruding at its base (base of stigma rounded in lateral view), approximately triangular. Column-foot approximately without accessories. 5telidia inconspicuously, triangular; tip acute; with a small, approximately subacute, tooth along the upper margin. Anther abaxially with a ridge towards its tip; front margin protruding. Pollinia 2. (After Vermeulen, 1993)
