Carex michauxiana, also known as Michaux's sedge, carex de Michaux[1] or yellowish sedge in Canada,[2] is a tussock-forming species of perennial sedge in the family Cyperaceae. It is native to eastern parts of North America and parts of Asia.[3]
The sedge has a tufted habit and is typically 10 to 60 cm (3.9 to 23.6 in) across. It has smooth culms with a triangular cross-section tat are 15 to 70 cm (5.9 to 27.6 in) in length. The yellowish to grenn leaves form from a thin outgrowth at the junction of leafstalk (a ligule). The leaves are flat to M-shaped and 1.2 to 4.6 mm (0.047 to 0.181 in) wide and smooth on the lower surface but covered with small dots on the upper surface particularly toward the end.[4]
Taxonomy
The species was first formally described by the botanist Johann Otto Boeckeler in 1877 as a part of the work Linnaea..[5] It has three synonyms;
- Carex rostrata Michx.
- Carex xanthophysa var. minor Dewey
- Carex xanthophysa var. nana Dewey.[4]
There are also two recognised subspecies;
- Carex michauxiana subsp. asiatica Hultén
- Carex michauxiana subsp. michauxiana.[4]
It is closely related to Carex dolichocarpa, which is found in Asia.[1]
