Cyperus bulbosus is a species of sedge found across Africa, the Middle East, Indian subcontinent, Southeast Asia, and Australia.

Typically green to straw in colour, the slender plant propagates via rhizomes (horizontal, underground stem extensions), ending at bulbs.

They consist of involucre bracts, meaning that a collection of leaf and petal-like extensions support the flower (just beneath the petals).

Lastly, glumes (membranous bracts) subacute (slightly rounded), with 3-5 nerves on either side of the keel, which in itself is approximately 3–5 mm long.

[2] A 12-year study, assessing the diet of Central Australian camels, found that Cyperus bulbosus was a common food plant as indicated by a "palatability index" score of 3.

[3] The Raso lark, endemic to the Cape Verde Islands, is heavily dependent on Cyperus bulbosus for food.

It has a particular impact on rice crop cultivation, in agriculture; competing for nutrients in spaces that may already be finite in supply.

[9] The small tubers which form on short stolons are a traditional bush tucker food for Australian Aboriginal peoples.

Due to invasive couch and buffel grass, Cyperus bulbosus numbers are known to be declining, particularly in central Australia, with reports that they may face eventual extinction.
