Dockrillia linguiformis is an epiphytic or lithophytic orchid with prostrate stems that produce wiry roots along almost their whole length. The roots are 1–4 cm (0.4–2 in) long and 3–4 mm (0.1–0.2 in) in diameter. There is a single leaf at the end of each branch of the stem. The leaf is oblong to egg-shaped, 2–4 cm (0.8–2 in) long and 8–15 mm (0.3–0.6 in) wide. It is 4–6 mm (0.16–0.24 in) thick and succulent with the upper surface smooth but with ridges and furrows. Up to twenty flowers are arranged in a raceme 5–15 cm (2–6 in) long. The dorsal sepal is linear to narrow lance-shaped, 15–22 mm (0.6–0.9 in) long and 3–4 mm (0.12–0.16 in) wide, the lateral sepals are 18–22 mm (0.7–0.9 in) long and 4–5 mm (0.16–0.20 in) wide, the petals slightly smaller. The petals and sepals are white to cream-coloured. The labellum is cream-coloured with pale purple markings and is 5–6 mm (0.20–0.24 in) long and 3–4 mm (0.12–0.16 in) wide.
