Carex capillacea, common name yellowleaf sedge in Tasmania, [4] is a species of sedge (in the Cyperaceae family) found in Assam, the far east of Russia, New Guinea, south east Australia, New Zealand, [2] Malesia, China, Japan and India. [5]

Description

Carex capillacea is densely tufted. The culms (up to 30 cm (12 in) long by 0.5 mm (0.020 in)) are erect and slender. The leaves are usually shorter than culms, and the sheath is green to pale brown. The inflorescence is erect and has one spike. The male portion of the spike is above the female portion. The style is divided into three parts. [6]

It flowers from October to December, fruits from October to July, [5] and the nuts are dispersed by granivory and wind. [7]

Distribution & habitat

In New Zealand it is found on the North Island on the Waimarino Plain, and the Moawhango and in the South Island from Nelson and Marlborough south to the lakes of Te Anau, Manapouri, Hauroko and east to Lumsden. Its preferred habitat is bogs, seepages, and the margins of ponds and pools. [5]

Conservation status

Assessments under the New Zealand Threat Classification System (NZTCS), declared it to be "At Risk – Naturally Uncommon" (NU) in 2013, and in 2017 to be "Threatened – Nationally Vulnerable" (NV). [1] In Tasmania, it is declared "Threatened". [4]

Taxonomy & naming

Carex capillacea was first described in 1858 by Francis Boott from specimens collected in the temperate eastern Himalayas at 10,000 to 12,000 feet (3,000 to 3,700 m) by Joseph Dalton Hooker in Sikkim and by William Griffith in Bhutan. [2] [3]

The specific epithet, capillacea, derives from the Latin capillus "hair" or "thread", and thus describes the plant as being thread-like. [5]

Uncinia is a genus of flowering plants in the family Cyperaceae, known as hook-sedges in Australia and as hook grasses or bastard grasses in New Zealand. The genus is characterised by the presence of a long hook formed by an extension of the rachilla, which is used to attach the fruit to passing animals (epizoochory), especially birds, and it is this feature which gives the genus its name, from the Latin uncinus, meaning a hook or barb.
