Description

edit

Cyperus squarrosus is a small sedge, reaching a maximum height between 10–16 cm (3.9–6.3 in). There are one to three short, thin leaves around the base of the plant. The inflorescence is a single spherical or bunched spike of up to 30 spikelets. Each spikelet is flat and has excurved awns, meaning the tip of each of the two to eight flowers on the spikelet curls outward. The spikelets are bright green to yellowish or brown. The curved awn tips and the small size of this sedge are good identifying characteristics.[4][5]
