Description

edit

Feldmark grass is a small and inconspicuous tufted bunchgrass, with its leaves growing to about 3 cm in height, and its flowering stems to about 7 cm. The leaves have broad, papery sheaths which are often curved or twisted spirally. The two to four spikelets are held against the flowering stem, with each containing two to four flowers.[2]

Distribution and habitat

edit

In Australia feldmark grass has a very restricted occurrence, being limited to about 3 ha of the Main Range of Kosciuszko National Park between Mount Lee and Mount Northcote. It also occurs in alpine parts of New Zealand. It is found only in feldmark communities, which are subject to freezing conditions and severe winds.[2]

Conservation status

edit

Feldmark grass is listed as being Vulnerable under Australia's Environment Protection and Biodiversity Conservation Act 1999.[3]
