Inflorescences several, elongated, many-flowered, flowering for a long time; peduncle short, 0.3-0.4 cm long; rachis flexuose, triangular in cross-section, to 4 cm long, internodes 0.15-0.75 cm long. Bracts widely patent, shorter than the flowers, trilobulate, 0.15 cm long, median lobule triangular, acute, concave, dorsally strongly keeled, with the keel decurrent on the rachis, lateral lobules minute, stipulaceous, triangular, acute. Flowers very small, 0.18 cm wide, 0.23 cm long. Sepals and petals connate into a 0.17 cm long, split tube, up to the apex 0.23 cm long. Free parts of the sepals ovate-triangular, subacuminate, acute, 0.1 cm long; free part of the petals similar but smaller, 0.06 cm long; all keeled outside, the keels decurrent on the tube.
