Type: Yumte 280 (holo L), from Indonesia, Papua, Bird's head Peninsula

Roots sprouting near the base of the rhizome, growing backwards along it until reaching the substrate. Rhizome up to 7 cm long, c. 1 mm in diameter, sections between pseudobulbs 0.15-0.2 cm long, patent to pendulous, bracts rather persistent. Pseudobulbs 0.45-0.55 by 0.15-0.25 cm, porrect, distant, cylindrical-obovoid, the new shoot arising about 1 mm from the base of the pseudobulb. Leaves sessile, blade 1.4-3.2 by 0.9-1 cm, index (length/width) 1.46-3.6, elliptic to ovate, acute. Inflorescence 1.7-2 cm long, 1-flowered; peduncle 0.5-0.8 cm long, porrect, non-floriferous bracts 2, the longest c. 2.3 mm long; floral bract c. 2 mm long, tubular, acute. Flowers moderately opening. Pedicel-and- ovary c. 5 mm long, basal node on a c. 1.7 mm long stump. Dorsal sepal c. 4 by 1.8 mm, index c. 2.2, more or less porrect, ovate, acute, margins entire, base rather broadly attached, rather thin, surface glabrous. Lateral sepals c. 4.3 by 1.9 mm, index 2.2-2.3, free, ovate-triangular, otherwise as the dorsal sepal. Petals c. 2 by 0.8 mm, index c. 2.5, porrect, ovate-oblong, subacute, margins finely erose, base broadly attached, thin, surface glabrous. Lip c. 3 by 1 mm, index c. 3, only slightly recurved, ovate, rounded to obtuse, margins finely papillose and distinctly ciliate except near the base, thick; adaxially concave and furrowed in the proximal two fifths of its length, with a flat, oblong, c. 0.6 mm long median callus, flat or slightly concave for the distal three fifths of its length, adaxial surface glabrous except for the papillose proximal end of the median callus; abaxially with a flat median ridge proximally, convex and deeply furrowed distally, surface long-hairy except near the base. Column c. 1.7 mm long; stigma ovate, without keels inside; foot widened and with patent, rounded lateral teeth just above the ligament; stelidia c. 1.2 mm long, downwards falcate, triangular-subulate, acute; rostellum not protruding; anther-cap abaxially with a crest, surface colliculate, front margin drawn out into a rounded beak; pollinia 4, more or less obovoid, all moderately flattened, the inner slightly shorter than the outer; no appendages.
