Carex adusta, commonly known as the lesser brown sedge,[1] swarthy sedge,[2] browned sedge,[3] or Carex brûlé,[4] is a species of sedge (Carex) in the section Ovales. First described scientifically in 1839 by Francis Boott, Adusta is Latin for "burnt," probably referring to the color.

Description

[edit]

Carex adusta is a densely tuft-forming, perennial, rhizomatous, grass-like plant growing up to 32 inches in height. Leaves are simple and alternate, and are linear in shape.[5] The plants have densely clustered culms that grow 2.5–8 cm (1.0–3.1 in) high, and leaves measuring 7–25 cm (2.8–9.8 in) long by 2–3.5 mm wide.[3] Inflorescence consists of up to 15 spikes, clustered together.[6] The fruit is an obovate to elliptic achene.[4]

Distribution and habitat

[edit]

This species is found in Canada and the northeastern United States, where it grows in dry, acidic, sandy soils,[7][8] woodlands, road beds and disturbed sites.[9]
