Schoenoplectiella mucronata
Species of grass-like plant
Schoenoplectiella mucronata is a species of flowering plant in the sedge family[1] known by the common names bog bulrush,[2] rough-seed bulrush,[3] and ricefield bulrush.[4] It is native to Eurasia, Africa and Australia.[5] It grows in moist and wet terrestrial habitat, and in shallow water. It is a perennial herb growing from a short, hard rhizome. The erect, three-angled stems grow in dense clumps and can reach a metre tall. The leaves take the form of sheaths wrapped around the base of stem, but they generally do not have blades. The inflorescence is a headlike cluster of cone-shaped spikelets accompanied by an angled, stiff bract which may look like a continuation of the stem.[6]: 228–30
It is a weed of rice fields in California.[4][7]
