Lyperanthus

Lyperanthus, commonly known as beak orchids, is a genus of flowering plants from the orchid family, Orchidaceae, that is endemic to Australia. There are two species, one in Western Australia and the other in four eastern Australian states, distinguished by their single long, narrow, leathery leaf and dull coloured flowers which have prominent short calli on their labellum. Both form loose colonies which reproduce asexually from their tubers, and sexually using their flowers.

==Description== Orchids in the genus Lyperanthus are terrestrial, perennial, deciduous, sympodial herbs usually with a few inconspicuous, fine roots and an oval-shaped, tuber lacking a protective sheath. Each year, new tubers develop on the ends of long, root-like stolons. There is a single, erect, leathery, stiff, linear to lance-shaped leaf, long, wide with tiny pimple-like glands on the lower surface. The distinctive leaf protruding though surrounding vegetation is often the first part of the orchid apparent to the observer.
