Glomera retusimentum J.J.Sm., Nova Guinea 18 (1935) 26, pl. 6, 13

Type: Docters van Leeuwen 11335 (holo BO)

Stem elongated, in cross section elliptic, not branched(?), rooting, collected part 60 cm long, when dried 0.25 cm thick, internodes 1.7-2.6 cm long. Leaves patent, lanceolate-linear, coriaceous, 5.25-9 cm long, 1-1.1 cm wide, narrowed towards the apex, apex unequal, obtuse to rounded-bilobulate, midrib grooved above, slightly prominent below; sheaths tubular, laterally compressed, in cross section narrowly elliptic, at the apex opposite the blade with a short, broad, appressed tooth, with longitudinal, thin, prominent nerves, minutely transversely rugulose, surpassing the internodes. Inflorescence head-like, strongly nodding, slightly elongated, few-flowered, secund, basal sheaths large, strongly concave, orbicular-ovate, apex narrowed and conduplicate, obtuse, keeled, keel apiculate, when not flattened 1.1 cm long. Lower bracts about as large as the sheath, orbicular, strongly concave, rather membranous, the upper ones the smallest and narrower. Flowers 8, 0.9 cm long. Median sepal incurved above the base, oblong, obtuse, dorsally below the apex long subulate-apiculate, 5-nerved, 0.95 cm long, 0.35 cm wide. Lateral sepals deeply connate, 5-nerved, obliquely falcate-triangular, when flattened the whole synsepal suborbicular, about 0.7 cm long, 0.75 cm wide, free apex obliquely rounded-triangular, 0.1 cm long, obtuse, dorsally below the apex long subulate-apiculate, free apex with the mucro 0.15 cm long; mentum saccate, pointing backwards, appressed to the ovary, shortly broadly retuse-bilobulate, 0.17 cm long. Petals incurved at the base, obliquely subspathulate-oblong, apex rounded-truncate, about 5-nerved, concave, 0.95 cm long, 0.38 cm wide. Lip at the base adnate to the column, shortly saccate, in total 0.45 cm long, to the apex of the ovary 0.38 cm long, adnate part 0.06 cm long, blade separated from the column at an almost right angle, slightly surpassing the column, somewhat recurved, at the base separated from the spur by a conspicuous transverse rib, when flattened transversely quadrangular, apex truncate, basal angles rounded in the middle, almost obtuse, at the base shortly narrowed, 0.23 cm long, 0.26 cm wide; spur pointing backwards, making an obtuse angle with the ovary, much shorter than the ovary, large, obliquely elliptic-conical, slightly laterally compressed, obtuse, along the dorsal side 0.2 cm long. Column short, in basal 1/3 adnate to the lip, dorsally convex, 0.23 cm long, clinandrium hollow, triangular, back wall equilaterally trapeziform, apex denticulate, auricles obliquely triangular, subulate-acuminate, front margins rounded-dilated, back margin minutely denticulate. Anther cucullate, in outline orbicular, 0.13 cm wide, apex thin marginate and retuse, at the base conical-gibbose and dorsally grooved. Pollinia 4, compressed, obliquely obovate, viscidium on either side with a triangular falcate tooth. Rostellum porrect, as long as the auricles, broad, broadly retuse, shortly rounded-bilobulate, with the lower margin of the stigma forming a broadly rounded bilabiate structure. 0varium with pedicel somewhat 6-grooved, 0.63 cm long.
