In frond-form and venation agreeing with T. keckii, differing in rather densely hairy lower surface of rachis and costae, thick hairs 0.5 mm long between veins on upper surface and indusia fringed with short hairs. The type consists of an apparently creeping short caudex bearing two fronds which are not quite fully expanded, the lamina probably 20 cm long when mature; apical section 9 cm long, deltoid and deeply lobed, pinnae 2 pairs, basal ones 11 cm long (stalks 15 mm), deeply lobed with one pair of adnate pinnules. On the same caudex are bases of much larger stipes which would have borne larger fronds
