Pterygodium leucanthum flowers

The flowers of Pterygodium leucanthum grow in a lax or loose inflorescence on a sturdy scape. They have pale green sepals and nearly white petals and lip. The specific name, leucanthum, means white flower.

The shallow cup-shaped hood made up of the median sepal and the rounded, concave lateral petals becomes 8 mm in diameter. The dorsal sepal, overshadowed by the petals, is concave, the lateral ones oblong and spreading below the flower centre. The lip is two-lobed, only 1,5 mm long, the lip appendage erect, about 6 mm long (Pooley, 1998; Wikipedia).
