Schoenoplectus mucronatus (L.) Palla[FNA23, HC2]
ricefield bulrush, rough-seed bulrush

Publication: Verh. K.K. Zool.-Bot. Ges. Wien. 38(Sitzungsber.): 49. 1888.

Origin: Introduced

selected vouchers: WTU

Notes: FNA23: "Schoenoplectus mucronatus was collected before 1900 in New Brunswick and New Jersey; apparently the plants did not persist. It has also been reported from New York and Pennsylvania; I have not seen specimens. Elsewhere, it has become firmly established. It is an important ricefield weed in California (M. K. Bellue 1947), where it was first observed in 1942 and is called "ricefield bulrush." It was first observed in the Midwest in 1971. Schoenoplectus mucronatus is cultivated for wildlife food near the Columbia River in Clark County, Washington, but apparently is not established in that area. Schoenoplectus mucronatus is very similar to S. triangulatus (Roxburgh) Soják of Asia, which differs in its larger spikelets, spikelet scales, and anthers."
