Taeniophyllum lobatum is a leafless, epiphytic or lithophytic herb that forms small clumps.

Two pale to bright yellow, resupinate flowers about 3 millimetres (0.12 in) long and wide are borne on a hairy white flowering stem 5–15 millimetres (0.20–0.59 in) long.

[2][3] Taeniophyllum lobatum was first formally described in 1956 by Alick Dockrill and the description was published in The Victorian Naturalist.

[4][5] The specific epithet (lobatum) is derived from the Latin word lobus meaning "an elongated projection or protuberance",[6] referring to "the large lateral lobes of the labellum".

[5] The yellow ribbonroot mostly grows on the smallest branches of rainforest trees sometimes on rocks.
