Species are seasonal geophytes growing from globose corms with fibrous netted tunics. The few leaves are lanceolate to linear, prominently nerved to somewhat plicate. The inflorescence is a spirally arranged spike. Flowers are yellow, orange or white, zygomorphic (bilaterally symmetrical) with unequal tepals and a short tube. The upper tepal is larger, held apart and hooded.
