Bulbophyllum chlorolirion J.J.Verm., Nordic J. Bot. 26 (2008) 147, fig. 11
Type: Jongejan cult. 658 (holo L), PNG, Daulo Pass
Roots sprouting mainly below the pseudobulbs. Rhizome 2-3 mm in diameter, sections between pseudobulbs 0.5-0.6 cm long, creeping, bracts not persistent. Pseudobulbs 1-1.8 by 0.6-1.2 cm, borne close together, erect, ovoid, surface rugose. Leaves: petiole 0.4-1.2 cm long; blade 2.8-6.5 by 1.4-1.6 cm, index (length/width) 2-4.7, elliptic, obtuse to subacute. Inflorescence 6-8 cm long, 1-flowered; peduncle 5.5-6.5 cm long, erect to patent; non-floriferous bracts c. 2, the longest c. 4 mm long; floral bract c. 3 mm long, tubular, acute. Flowers moderately opening. Pedicel-with-ovary c. 4 mm long, basal node coinciding with the bract attachment. Dorsal sepal c. 15 by 3 mm, index c. 5, recurved, ovate, acute, margins entire, base rather broadly attached, thin, surface glabrous. Lateral sepals c. 16 by 4 mm, index c. 4, free, otherwise as the dorsal sepal. Petals c. 14 by 3.5 mm, index c. 4, recurved, ovate, acuminate, margins about entire, base narrowly attached, thin, surface glabrous. Lip c. 4.5 by 1.2 mm, index 3.7-3.8, recurved near the base, triangular, acute, margins with two pairs of auricles: one pair close to the ligament, retrorse, ovate, rounded, one pair reaching up to about one fifth of the length of the lip, low and wide, broadly rounded, beyond these the lip margins long-ciliate, rather thick; adaxially concave proximally, more or less flat distally, with three ridges, an obtuse median starting near the base and soon grading into the lip surface, and two more ridges close to the median, obtuse, continuing up to about half of the length of the lip and with their crests touching over the furrow in between for a short distance beyond the median ridge, adaxial surface very finely and densely papillose to shortly hairy; abaxially with a short, rounded median ridge near the base, elsewhere more or less flat, somewhat furrowed, surface glabrous. Column c. 1.2 mm long; stigma transversely elliptic, without keels inside; foot not widened; stelidia c. 0.8 mm long, oblong, slightly tapering, tip deeply emarginate, with obtuse lobes with finely papillose margins; anther-cap abaxially with a large, wide, rounded crest, surface papillose, front margin drawn out into a truncate, thin beak; pollinia not seen.

Colours: Sepals and petals metallic green at the base, purple towards the tip and the margins, and with three purple nerves, lip purple, abaxially white near the base.
