Distribution

Chamaeanthus consists of three species distributed in southern Thailand, Java, and Borneo, north to Taiwan and the Philippines.

Ecology

All three species are epiphytes from 0 to 900 m. Chamaeanthus brachystachys is recorded as epiphytic in hill forests on ultramafic substrate in Sabah and in swampy podsol forest in southern Kalimantan, Borneo. Comber (1990) recorded C. brachystachys growing in dry areas on isolated trees in Java. Chamaeanthus wenzelii Ames occurs on trees along seashores in the Philippines.

Inflorescence lateral, simple, with up to about 20 flowers; rachis usually clavate. Flowers ephemeral, only a few open at a time, greenish yellow, superficially resembling Bulbophyllum. Sepals and petals similar, often linear and acuminate, to 4–6 × 3 mm; lateral sepals adnate to column foot.
