Description

edit

Chiloschista segawae is an epiphytic, leafless herb that forms clumps with many flattened greenish, photosynthetic roots up to 350 millimetres (14 in) long radiating from inconspicuous stems. Between six and fifteen slightly fleshy, whitish green or yellow resupinate flowers are arranged along a pendulous flowering stem 50–150 millimetres (2.0–5.9 in) long. The dorsal sepal is broadly elliptic, 3–5 millimetres (0.12–0.20 in) long, 2.5–4 millimetres (0.098–0.16 in) wide, the lateral sepals are broadly elliptic to egg-shaped, 4.5–6 millimetres (0.18–0.24 in) long, 3.5–4 millimetres (0.14–0.16 in) wide and the petals are elliptic, 4–6 millimetres (0.16–0.24 in) long, 3.5–4 millimetres (0.14–0.16 in) wide. The labellum is 5–6 millimetres (0.20–0.24 in) long with three lobes. The side lobes are erect and the middle lobe is small with a sac-like base. Flowering occurs from April to May.
