Ambuchanania
Ambuchanania leucobryoides is the only species in the monotypic genus Ambuchanania. It is a Sphagnum-like moss endemic to Tasmania. Originally described as a species of Sphagnum, it is now a separate genus named after the original collector Alex M. Buchanan, an Australian botanist from the Tasmanian Herbarium in Hobart,. A. leucobryoides differs from the family Sphagnaceae in having elongate antheridia. It is entirely restricted to south-west Tasmanian Wilderness [World Heritage Area|Tasmania's Wilderness World Heritage Area] where it occurs on white Precambrian quartzitic sand deposited by alluvial flows, and on margins of buttongrass sedge land. Species most commonly found in association with A. leucobryoides include: Leptocarpus tenax, Chordifex hookeri, and Actinotus suffocatus. Currently, A. leucobryoides is listed as rare under the Tasmanian Threatened Species Protection Act 1995.
