In florescence an elongated, rather dense raceme, erect, c. 43 cm. c. 34-flowered. Peduncle c. 24.5 cm. bracts c. 5 (4 present on portion of inflorescence available), the longest c. 10 mm long. Rhachis slightly thickened, c. 15 x 0.3 cm. finely papillose. Floral bracts triangular, c. 2.2 x 1.2 mm. acute to acuminate. Flowers secund. not fully opening, several simultaneously, anthesis from the top of the rhachis downwards. Pedicel and ovary c. 5.5 mm long, finely papillose distally. basal node ± flush with the surface of the rhachis. Median sepal porrect to recurved, ovatetriangular, c. 7.5 x 2.2 mm, index c. 3.4; acute, margins ciliate, base rather broadly attached; rather thick, surface glabrous adaxially, finely papillose abaxially. Lateral sepals recurved, triangular, c. 7.5 x 3.6 mm, index c.2.1. upper margin ciliolate with scattered longer hairs in between: otherwise as the median sepal. Petals porrect, triangular-ovate, c. 3.4 x 1.4 mm, index 2.4—2.5; subacute, margins long ciliate, hairs longer towards the tip. base rather broadly attached; rather thin, surface glabrous. Lip curved close to the base, oblong, c. 7.5 x 2 mm, index 3.7—3.8; rounded, margins ciliolate proximally, long ciliate distally, glabrous in between; thick; adaxially slightly concave near the base, without a basal callus, with a median furrow reaching up to c. 1/4 of the lip, slightly convex elsewhere, surface glabrous; abaxially with a rounded ridge near the base, surface slightly convex, glabrous but with a finely pubescent patch in front of the basal ridge. Column c. 1.8 mm long, foot slightly swollen, abaxial side with a short, obtuse spur near the tip. Stelidia c. 0.8 mm long, acute, obliquely, rectangular in outline with a distinct, antrorse, triangular, acute tooth along the upper margin, and a similar, but obtuse tooth along the lower. Anther, front margin pilose, abaxial surface finely papillose. Colours: Rhachis yellowish, slightly suffused with red. Bract, pedicel and ovary yellowish green, marked brownish red distally.
