Carex hystericina is a species of sedge known by the common names bottlebrush sedge [1] and porcupine sedge. [2] It is native to North America and Canada through to Mexico and Jamaica. [3]
This sedge produces dense or loose clumps of triangular stems up to a meter tall from short rhizomes. Leaves are green, basal and alternate, sometimes surpassing the stems in height. Basal leaves are fibrous and purplish in colour. [2] The inflorescence is several centimeters long and is accompanied by a bract which is longer than the spikes. There are separate staminate (male) and pistillate (female) spikes on the same plant. [2] The fruits are coated in perigynia with pointed, toothed tips. [4]
Carex hystericina grows in wet habitat such as wetlands and riverbanks, especially on calcareous soils. [4]
