Tropidia viridifusca, commonly known as the dark crown orchid,[2] is an evergreen, terrestrial plant with thin, pleated, dark green leaves on a thin, upright stem with up to seven green and brown flowers crowded on a short flowering stem on top.

Tropidia viridifusca is an evergreen, terrestrial herb with thin but tough, upright stems 150–300 mm (6–10 in) tall with between four and seven thin, pleated, dark green leaves 50–150 mm (2–6 in) long and 10–20 mm (0.4–0.8 in) wide.

[2][3] Tropidia viridifusca was first formally described in 1929 by Friedrich Wilhelm Ludwig Kraenzlin and the description was published in Vierteljahrsschrift der Naturforschenden Gesellschaft in Zürich.

[1][4] The specific epithet (viridifusca) is derived from the Latin words viridis meaning "green"[5]: 837  and fuscus meaning "dusky" or "tawny".

[5]: 168 The dark crown is only known from Grande Terre in New Caledonia, Vanuatu and Norfolk Island where it grows on slopes in shady forest.
