Plants small, with a short stem up to 5 cm long, 5 mm in diameter. Leaves spaced close together, oblong or oboval, unequally bilobed at the apex, 10-15 cm long, 1.5-2 cm wide. Inflorescences arising below the leaves, 6-10 cm long, 6- to 10-flowered; bracts small. Flowers white; sepals sub-elliptic, obtuse, dorsal sepal 4-5 mm long, 2-3 mm wide, lateral sepals 5 mm long, 1.5 mm wide; petals broadly elliptic, rounded at the apex, 5-6 mm long, 4-5 mm wide; lip broadly rhomboid, 5 mm long, 8 mm wide; spur narrow, inflated at the apex, slightly incurved, ca. 10 mm long, 1.5 mm in diameter.
Epiphyte on trees in montane forest; ca 2000 m.
As given for the genus, cool growing epiphyte.
Easily distinguished from the other species in the genus by its larger leaves, as well as its geographical distribution. Daniel Geerinck (1992) prefers to retain this species in Diaphananthe as Victor Summerhayes originally described it.
