Carex abscondita, the thicket sedge, is a North American species of sedge first described by Kenneth Mackenzie in 1910.[1][2]

Distribution and habitat

[edit]

It grows along the central and eastern United States, from eastern Texas to southern Missouri, east to the Atlantic coast, and north to New Hampshire.[3] It grows in moist areas of forests, flood plains, shrublands, and swamps.[4]

Description

[edit]

Carex abscondita is a tussock-forming perennial plant, grown from a rhizome. Leaves are green in colour, flat, smooth, with whitish sheaths. The lowest bract has a sheath in excess of 4mm. The lowest spike has a peduncle, while the uppermost spike bears only staminate flowers.[5]

It is closely related to and sometimes confused with Carex digitalis, which, compared to Carex abscondita, has longer flowering stems relative to the leaves, wider staminate spikes, and often has thinner leaves.[4]
