Type: Jongejan cult. 1310 (holo L), PNG, Madang Prov.

Roots sprouting mainly below or near the pseudobulbs. Rhizome 1.8-2.2 mm in diameter, sections between pseudobulbs 1.3-2 cm long, creeping, bracts not persistent. Pseudobulbs 0.9-1.2 by 1-1.6 cm, somewhat distant, shortly ovoid to thickly lenticular. Leaves pendulous; petiole 4.5-6 cm long; blade 16-18 by 0.45-0.75 cm, index (length/width) 24-32, falcate, elliptic, acute. Inflorescence 2-2.5 cm long, 1-flowered; peduncle c. 0.9 cm long, erect to patent; non-floriferous bracts c. 3, the longest c. 3.5 mm long; floral bract tubular, 6-7 mm long, apiculate. Flowers widely opening. Pedicel-with-ovary c. 12 mm long, basal node on a c. 2.5 mm long stump. Dorsal sepal c. 22 by 3 mm, index 7-8, recurved to spreading, ovate, tapering distally, acute, margins entire, base rather broadly attached, thick, surface glabrous. Lateral sepals c. 23 by 4 mm, index 5.7by 6, free, spreading, lower margin sharply folded inwards, slightly erose, otherwise as the dorsal sepal. Petals c. 3 by 2 mm, index c. 1.5, recurved, strongly curved downwards, ovate-triangular, tapering distally and with a distinct, rounded lobe proximally along the lower margin, acute, margins entire, base narrowly attached, thin, surface glabrous. Lip c. 11.5 by1.8 mm, index c. 6.4, attached to the column-foot by a transverse, rather narrow area and partly mobile, gently curved over its entire length, ovate, acute, margins entire, thick and spongy; adaxially with a transverse ridge just above the area of attachment, with a c. 0.8 mm long concave area in front, distally abruptly passing into a more or less flat area, otherwise convex, with a somewhat corrugated surface; abaxially convex proximally, elsewhere with a shallow median furrow, surface glabrous. Column c. 3.5 mm long, gently curved, somewhat more so about half-way; stigma narrowly triangular, without keels inside, with a conical, obtuse callus well below it; foot widened into two thick more or less lateral calli just above the area of attachment; stelidia c. 0.9 mm long, deltoid-triangular, acute, with the upper margin distinctly erose, with a deltoid, apiculate tooth along the lower margin; anther-cap abaxially without a crest, surface finely papillose, front margin drawn out into a small, triangular, acute beak; pollinia 4, obovoid, the inner flat, somewhat enveloped by the recurved lateral sides of the outer; no appendages.
