Cyperus concinnus (common name - trim flat-sedge)[1] is a sedge of the family Cyperaceae that is native to Australia,[2] and found in New South Wales, Queensland, the Northern Territory, South Australia, Victoria and Western Australia.[3]

Description

[edit]

The tufted perennial rhizomatous sedge typically grows to a height of 0.2 to 0.8 metres (0.7 to 2.6 ft) and produces brown flowers.[2] It has culms with a triangular cross section. The culms are slightly swollen at the base and rough and scabrous above with a length of 15 to 65 cm (5.9 to 25.6 in) and a diameter of 1 to 3 m (3 ft 3 in to 9 ft 10 in). The leaves have a prominent transverse septa and are about the same length of the culms and have a width of 1 to 2 mm (0.039 to 0.079 in). The inflorescences have three to five primary branches with a length up to 4 cm (1.6 in) forming clusters that have a diameter of about 10 mm (0.39 in). There are one to six flattened spikelets per cluster with a length of 4 to 10 mm (0.16 to 0.39 in) and a width of 1 to 3 mm (0.039 to 0.118 in).[1]

Distribution

[edit]

It is found in all the mainland states and territories of Australia except for South Australia.[4] In Western Australia it is found in swamps and around creeks and pools the Mid West, Pilbara and Goldfields-Esperance regions where it grows in sandy-clay soils.[2]

Taxonomy

[edit]

It was first described in 1810 by Robert Brown as a part of the work Prodromus Florae Novae Hollandiae et Insulae Van Diemen.[5][6]
