Carex archeri, known as Archer's sedge,[3] is a species of sedge in the genus Carex, endemic to south-eastern Australia.
Description
[edit]Carex archeri grows up to 25 centimetres (10 in) high, with leaves less than 0.5 millimetres (0.02 in) wide.[4] Its inflorescence comprises a single spike subtended by a bract that is longer than the inflorescence. The spike contains few flowers, with the female flowers towards the base of the spike, and a very short portion towards the tip containing male flowers.[4] The glumes of the female flowers are 2.5–4.0 mm (0.098–0.157 in) long, and the utricles that form in the female flowers are 3–5 mm (0.12–0.20 in) long, with a 1.3–2.5-millimetre (0.05–0.10 in) notched beak.[4]
Specimens of C. archeri may be mistaken for stunted examples of either of two species classified in the same section, C. raleighii and C. hebes.[4]
Distribution and ecology
[edit]Carex archeri grows in bogs, alpine heath and tussock grassland in upland areas of Tasmania and the Australian Alps of Victoria and New South Wales.[4][5] Within New South Wales, it is limited to parts of Kosciuszko National Park around Club Lake and the upper reaches of the Thredbo River.[5]
Conservation
[edit]Carex archeri is not listed on the Environment Protection and Biodiversity Conservation Act 1999,[6] but it is subject to protection by the state of New South Wales as an endangered species,[5] and as a vulnerable species in Victoria.[3]
Taxonomy
[edit]Carex archeri was first described by Francis Boott in 1858,[3] and named in honour of William Archer.[7] Archer had collected the type material in the western mountains of Tasmania.[1]
