Carex albicans

Carex albicans, commonly called whitetinge sedge,[1] is a species of flowering plant in the sedge family (Cyperaceae). It is native to the eastern North America, where it is found in Canada and the United States.[1][2] Its typical natural habitat is dry forests and woodlands.[2][3]

Carex albicans is a perennial graminoid. It produces fruits in early spring, which are dispersed in part by ants.[4]

Carex section Acrocystis is known for being taxonomically difficult, with new species still being described in eastern North America.[5] Two species in this section, Carex emmonsii and Carex physorhyncha, have historically been treated as varieties of Carex albicans due to the three taxa's strong morphological and biochemical similarities.[4] However, modern treatments of the 2010s often separate them at the species level.[2][6]
