Carex pauciflora

Carex pauciflora, the few-flowered sedge,

cool temperate, subarctic, and mountainous regions of the Northern Hemisphere. The specific epithet pauciflora refers to the Latin term for 'few flowered'.[3][4]

Description

Carex pauciflora grows to 60 centimetres (24 in) tall at most, although it more commonly grows to 10–40 centimetres (3.9–15.7 in) tall. It is a rhizomatous

perennial with culms that grow alone or in diffuse clusters.[5] A survey of populations in Estonia assessed a mean rhizome length of 4.1 centimetres (1.6 in), although rhizomes up to 35 centimetres (14 in) long have been recorded.[6] The blades may be up to 13 centimetres (5.1 in) long and 1.6 millimetres (0.063 in) wide, and no more than three blades occur on each culm.[5] Every part of the plant is hairless.[7]

Each flower only contains either male or female reproductive structures, although the plants themselves are

spike, with female flowers located below the male flowers on the spike.[8] Female flowers may be less well-developed in unfavorable habitats.[9]

Carex pauciflora seeds are dispersed mechanically. The perigynium is launched outward when it comes into contact with an object and tissue at its base is compressed, which then acts as a spring when the pressure is released.[10]

Distribution and habitat

Carex pauciflora has a

Carpathians[13] and in the Ovruch Raion of the Zhytomyr Oblast near the border with Belarus.[14]

Recreational activity threatens some populations in North America.[5] The species has declined in Estonia due to development of its wetland habitats, although it has not been as severely impacted as some other sedge species.[6] Populations in the Ukrainian Carpathians are threatened by climate change. The bogs that Carex pauciflora inhabits in the Ukrainian Carpathians are drying out and being invaded by shrubs, and fens that the sedge also inhabits are being invaded by trees and shrubs such as Pinus mugo, Alnus alnobetula, Salix silesiaca, and Picea abies. Manual removal of more competitive non-wetland plants has been suggested as a conservation measure.[13]
