The plant blooms in the late winter through later spring on a lateral, apical, few flowered, erect to arching, velvet-hairy, 3-8 cm long, raceme with broadly ovate-elliptic, sheaths and broadly elliptic, velvet-hairy floral bracts.

Dorsal sepal is elliptic, 8-10 x 4-5 mm, blunt; lateral sepals slightly shorter and broader. Petals are narrowly elliptic-obovate, 7-8 x 3.5-4 mm; lip broadly heart-shaped or broadly ovate, 3.5-4 x 2-3 mm, with a short sharp point, with a cushionlike callus in basal half. Column is curved forward at right angle. Rigid Eria is found in Central Himalaya to China (S. Yunnan) and W. Malesia, at altitudes of 600-1700 m. Flowering: May-June.
