Baumea preissii

Baumea preissii is a flowering plant in the sedge family Cyperaceae, which is native to Western Australia.

The robust grass-like plant is rhizomatous and perennial; it typically grows to a height of 0.2 to 2 m, and colonises easily. It blooms between July and December, producing purple-brown flowers.

It is found in swamps and on the margins of lakes and creeks along coastal areas in the Wheatbelt, Peel, South West, Great Southern, and Goldfields-Esperance, where it grows in water-logged silty-sand soils.
