Bijdr. (1825) 354
Sympodial terrestrial plants with short to rather long rhizomes. Pseudobulbs consisting of one or a few internodes, one-leaved. Leaves not sheathing at the base, glabrous, plicate, not deciduous, often with a long petiole, convolute, thin-textured. Inflorescence arising on a specialised leafless shoot (heteranthous), or lateral from the base of the pseudobulb, a few- to many-flowered raceme. Flowers small to rather large, resupinate. Sepals free. Petals free, fairly similar to the sepals. Lip without or with a short spur, not mobile. Column-foot very short to rather long. Pollinia 8, solid, caudicles present, stipe and viscidium absent.

Members of this genus combine the habit of Chrysoglossum with the floral aspect of Eulophia; from both they differ in having 8 pollinia. Tainia is not often cultivated.
