Sphagnales

The Sphagnaceae is a family of moss with only one living genus Sphagnum.

The Sphagnales is an order of mosses with four living genera: Ambuchanania, Eosphagnum, Flatbergium, and Sphagnum. The genus Sphagnum contains the largest number of species currently discovered (about 200, number varying according to the various authors). The other genera are currently limited to one species each.

Ambuchananiaceae is a family of moss in the order Sphagnales with only two genera, Ambuchanania and Eosphagnum.

Flatbergium is a genus of moss with two accepted species. Flatbergium sericeum and Flatbergium novo-caledoniae, originally described as species of Sphagnum, are now considered part of this separate genus on the basis of genetic differences.

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, (b.1944) an Australian botanist from the Tasmanian Herbarium in Hobart, (it was first collected in 1987). A. leucobryoides differs from the family Sphagnaceae in having elongate antheridia. It is entirely restricted to south-west Tasmania's Wilderness World Heritage Area where it occurs on white Precambrian quartzitic sand deposited by all

Eosphagnum inretortum is a species of moss, and the only species of the genus Eosphagnum. Originally described as a species of Sphagnum, it is now a separate genus on the basis of morphological and genetic differences.
