Carex schweinitzii, common name Schweinitz's sedge, is a Carex species native to North America. It is a perennial.[1]

Description

[edit]

Carex schweinitzii is a sedge with long, slender rhizomes that range from 0.2–0.65 m (7.9 in – 2 ft 1.6 in) in height. Its ligules are wider than long. Its peduncles are short, and its male spikelets are solitary while its female spikelets are spreading and erect.[2]

Carex schweinitzii occurs most often in calcium-rich soils near water, such as in springheads, springy seeps, and wet ground along cold spring-fed streams. More rarely the plant occurs in mixed or coniferous cover and even in the open.[3] The plant is mostly local but is abundant where it is found.[4]
