Inflorescence terminal, 8-25 cm long, dependent, with 1-3 sterile flowers at the base and 6-15 flowers above, 8-15 mm apart, peduncle narrowly 4-winged at the base, becoming 3-winged and wider (5-6 mm) towards the apex, glabrous. Flowers small, nonresupinate, pale orange to brownish yellow, with green nerves on the lip. Floral bracts 3-4 mm long, linear, acuminate, membranous. Pedicel and ovary 0.8-3 mm long, straight, slender, glabrous. Dorsal sepal 5.5-10 mm long, 1.1-1.5 mm wide, oblong-lanceolate, acute to acuminate, margins revolute, thin, delicate, glabrous.
