Cyperus mindorensis

Cyperus mindorensis, commonly known as the white water sedge, is a species of perennial sedge in the family Cyperaceae.^[1][2] It is a grass-like plant in the large genus Cyperus and is distributed across the Old World Tropics, Australia, and the Pacific Islands.^[3] This species typically grows in wet habitats and is often considered a weed rather than a cultivated plant.

Cyperus mindorensis is a perennial sedge that grows up to 0.6 m tall. It has a creeping growth habit and spreads through a long rhizome (underground horizontal stem), which produces flowering stems either in tufts or singly.^[4][5]

The leaves are linear, measuring 1.5–3 mm in width and up to 55 cm in length. They arise from a brown to purplish-brown leaf sheath. Its overall appearance is grass-like, with slender stems and narrow leaves.

Cyperus mindorensis reproduces vegetatively through its rhizomes as well as by seed production. It is usually regarded as a weed in agricultural and natural ecosystems due to its rapid growth and spreading habit.
