Dawsonia longiseta is a species of moss in the family Polytrichaceae endemic to eastern Australia .[2]
Description
D. longiseta is an erect moss with bluish green leaves that grows in open colonies or as scattered individuals reaching 1–3 cm (0.39–1.18 in) tall. The leaves are stiff and pointed, measuring approximately 5–7 mm (0.20–0.28 in) long, with a broad nerve and slightly serrated edge. In dry conditions, the leaves turn brown and rest alongside the stem pointing upwards. When in the sporophyte stage, plants produce capsules on stalks that grow to 2–4 cm (0.79–1.57 in) tall. Developing capsules are covered by hairy, pinkish calyptrae, while mature capsules are small and dark, sometimes with the white hairs of the peristome visible.[2][3]
Distribution and habitat
D. longiseta can be found in south-eastern South Australia, eastern Queensland, New South Wales, Australian Capital Territory, and Victoria. It grows in shaded situations on clay, sandy, or rocky soil across a range of habitats including river banks, roadsides, gullies, and sclerophyll forests. It can be found from sea level up to 1000 metres.[2]
