Epiphytic plants with stems 10 cm long or more, with numerous adventitious, fleshy roots. Leaves 4—5, lying in one plane, 5-5 x 2 cm, oblong to spathulate, narrowing at the base, bilobed at the apex. Inflorescence as long as the leaves, 1-2-flowered; peduncle slender, 3-4cm long; bracts brown, ovate, 3.5 cm long. Flowers fleshy, greenish-white. Sepals 10 x 4mm, spathulate, rounded or somewhat apiculate at the apex. Petals similar, but slightly longer and broader. Lip entire, glabrous, horizontal, subpandurate (fiddleshaped), 20 x 12 mm; spur 13 cm long, filiform. Column 2.5 mm long, with rounded auricles at the apex.
This charming species was described in 1962 by J Toilliez-Genoud and J Bosser and named in honour of Mlle Keraudren, who collected the type specimen.
This very rare species occurs in humid, high altitude forest east of Lake Alaotra.
It has a long spur, like Neobathiea grandidieriana, but differs mainly in the subpandurate lip.
