Type: Docters van Leeuwen 10215 (holo BO; iso BISH)

Tuber subglobose, 0.33-0.5 cm diam. Subterranean stem coarsely pilose, 0.8-4.5 cm long, emitting pilose stolons. Stem above the ground 0.5-1.3 cm long; near the base with a tubular, filiform-subulate-acuminate, 0.5 cm long sheath. Leaf sessile, cordate, shortly acutely acuminate, basal lobes rounded, not overlapping, midrib dorsally prominent, 1.1-1.5 cm long, including the basal lobes 1.25-1.8 cm long, 0.5-1.5 cm wide. Floral bract at the base appressed to the ovary, otherwise patent, concave, at the base triangular, gradually long filiform-narrowed, 1-nerved, 0.68 cm long, at the base 0.14 cm wide. Median sepal pointing backwards, strongly incurved, strongly concave, narrowly oblong, somewhat dilated towards the apex, obtuse, long abruptly subulate-acuminate, 1.55 cm long, acumen about 0.2 cm long, at the base 0.23 cm wide, in apical part 0.42 cm wide, at the base somewhat contracted, nerves 5, dorsally prominent, especially the midrib. Lateral sepals elongated, linear-filiform, triangular, channeled, 1-nerved, 2.35 cm long, at the base 0.08 cm wide. Petals similar to the lateral sepals but longer, 3.8 cm long, about 0.1 cm wide. Lip pointing backwards, parallel to the median sepal, strongly recurved, margin incurved, narrowly overlapping, in the basal part tubular, blade strongly dilated, transversely reniform-ovate, irregularly dentate-serrate, apex in the middle apiculate, without callus, inside especially in the middle very minutely papillose, 17-nerved, when almost flattened 1 cm long, 1.3 cm wide, with 2 short, divergent, conical, obtuse, 0.15 cm long spurs. Column pointing backwards, making an obtuse angle with the ovary, dorsally convex, at the base with a callus adnate to the base of the lip, including the anther 0.23 cm long. Anther cucullate, porrect, quadrangular, conduplicate, apex rounded-bilobulate. Stigma suborbicular, concave, margins raised, weakly incurved. Ovary strongly recurved, rather thick, 6-grooved, 0.3 cm long. Fruit (immature seen) sessile, oblong, 0.63 cm long. (After Smith, 1935)
