The Bryophyta are the mosses, the largest living group of non-vascular land plants. Mosses are distinguished by the presence of distinct leaves and multicellular rhizoids on the gametophyte (which is the dominant part of the life-cycle, supporting the dependent sporophytes), and of a columnella (a cylinder of sterile cells) within the spore capsule (De Luna et al. 2003). Within the mosses, all authors support a division between the basalmost Sphagnopsida and the remaining mosses, with the Polytrichopsida and Bryopsida together forming a clade distinguished by a spore capsule opening through an operculum rather than dehiscently as in more basal forms. Sphagnopsida are represented in the modern flora by the genera Sphagnum and Ambuchanania; Ambuchanania leucobryoides is a rare species found growing in sandy washes in a small number of localities in Tasmania (Threatened Species Section, Tasmania, 2008).

Polytrichopsida and Bryopsida are distinguished by the forms of the teeth around the capsule opening (forming the peristome): in Polytrichopsida, they are nematodontous (formed from entire cells) while in Bryopsida they are arthrodontous (formed from fragments of cell walls). Within the Bryopsida, the peristome comprises a single circlet of teeth in members of the subclass Dicranidae whereas members of other subclasses typically have a peristome of two circlets (reduced or lost in some taxa).
