Tropidia territorialis is an evergreen, terrestrial herb with thin, upright stems 100–200 mm (4–8 in) tall with between three and six thin, pleated, dark green leaves 70–120 mm (3–5 in) long and 15–20 mm (0.6–0.8 in) wide.

Above the leaves is a flowering stem 10–20 mm (0.4–0.8 in) long with between ten and twenty resupinate green and white flowers.

[2][3] Tropidia territorialis was first formally described in 2004 by David Jones and Mark Clements and the description was published in The Orchadian.
