Carex ventosa, also known as Chatham Islands forest sedge,[1] is a tussock-forming species of perennial sedge in the family Cyperaceae. It is native to the Chatham Islands.[2]
The sedge has a stout and quite leafy habit with a short and erect rhizome typically with a width of about 20 mm (0.79 in) and is found to grow mostly in well drained soils. It has smooth culms that can be scabrous below the inflorescence. The culms have a triangular cross-section and a length that is usually 0.45 to 1 m (1 ft 6 in to 3 ft 3 in) but can be as long as 1.5 m (4 ft 11 in) and a width of 1 to 4 mm (0.039 to 0.157 in) and are surrounded at the base by drown coloured sheaths. The pale green to light grey-green double folded leaves are usually as long as or slightly longer than the culms and have a width of 5 to 11 mm (0.20 to 0.43 in) and have rough margins. The inflorescences contain 7 to 15 spikes and are 0.2 to 1 mm (0.0079 to 0.0394 in) in length.[1]
