Type: Stocker cult. 7 (holo SING; iso L), from PNG, Erave

(vegetative parts not seen). Inflorescence a rather lax raceme, c. 10-flowered; peduncle erect to patent; rachis c. 16 cm long, arching; floral bracts 11-14 mm long, ovate, the lowermost tubular, acute. Flowers with the lip pointing towards the top of the rachis , wide-opening, many simultaneously. Pedicel-with-ovary 22-32 mm long, basal node flush with the surface of the rachis. Dorsal sepal c. 16 by 8 mm, index c. 2, recurved, sub-triangular with acute edges near the base, acute, margins entire, base narrowly attached, central part thick, but rather thin distally and towards the margins, surface glabrous. Lateral sepals c. 37 by 12 mm, index c. 3.1, free, spreading, falcate, about elliptic with a triangular, acute tooth along its upper margin, at one third of its length, rather thick, otherwise as the dorsal sepal. Petals c. 9 by 3 mm, index c. 3 (not flattened), porrect, more or less obovate, entire top part folded twice, once outwards, with the fold itself formed into a pouch, and then backwards again; top rounded-truncate, margins erose distally; base decurrent, in particular the lower margin which continues as a narrow seam along the column- foot for c. 8 mm, thin, surface glabrous. Lip c. 9 by 7 mm, index c. 1.3 (not flattened), recurved near the base, otherwise more or less straight, ovate-triangular, rounded, margins entire, very thick; adaxially concave, with 3 ridges: an obtuse median ridge starting at the base, continuing up to three quarters of the length of the lip, and bordered on both sides by a deep furrow, and two high, obtuse ridges starting near the base, then converging slightly and running more or less parallel to the margin, distally meeting the margin again, surface glabrous but with fine, transverse wrinkles in the areas between the lateral ridges and the margin; abaxially convex, with a shallow median furrow, surface glabrous. Column c. 6.5 mm long; stigma transversely elliptic, without keels inside, with a slight swelling well below its base; foot elongated so that the attachment of the petals and the lateral sepals are separated by a c. 9 mm long gap, distally widened, with two diverging, obtuse teeth below the attachment of the lip; stelidia c. 1.5 mm long, triangular with a convex upper margin, acute, with a patent, deltoid, rounded wing along the lower margin; anther-cap abaxially without a crest, surface more or less glabrous, front margin not drawn out, widely rounded; pollinia 4 not seen; without appendages (field observation on fresh flower).

Colours: Pedicel-with-ovary light green, dorsal sepal light green, abaxially near the base brownish red, lateral sepals light yellowish green, abaxially the basal one third to half with a brownish red stripe, petals light yellowish green, lip light yellowish green, brownish red towards the margins, column including foot whitish yellow, pollinia yellow.
