Cyperus bulbosus

Description

Cyperus bulbosus is a species of sedge found across Africa, the Middle East, Indian subcontinent, Southeast Asia, and Australia. In Australia, it is commonly called (Australian) bush onion or "wild onion", but is not related to the onion or other Alliaceae. It is a component of Australian bushfood, but is considered an agricultural weed in other areas. C. bulbosus is perennial and rhizomatous, with fine grassy foliage and triangular culms. The inflorescence is rarely branched and consists of a cluster of spikes of reddish-brown bracts, eventually producing small, three-sided seeds. The small tubers which form on short stolons are a traditional bush tucker food for Australian Aborigines. They are dug up on creek banks when the grass of the onion has dried out. The husk can also be eaten. They are eaten raw or cooked in the hot earth by the fire.
