The Bruchiaceae are a modest-sized family of about one hundred species and traditionally placed in general relationship with the Dicranaceae. Trematodon, the largest genus and the only one occurring in New Zealand, is most diverse in temperate regions of the southern hemisphere, and probably has about 80 species worldwide. Species of Trematodon are terrestrial in insolated and ephemeral sites and recognisable by their distinctive erect or curved capsules with long, narrow, often strumose necks that equal or exceed the urn length. The capsules are operculate and often peristomate. Three species of Trematodon are accepted for the N.Z. flora. The other significant genus in the family, Bruchia, also consists of terrestrial plants growing in disturbed terrestrial habitats. They also have long-necked capsules, but in Bruchia these are cleistocarpous. Bruchia is a less speciose genus, most diverse in North and South America; although it does not occur in N.Z. it has been recorded from Australia. The other three genera sometimes placed in this family are small genera of limited geographic distribution. The members of the Bruchiaceae are often interpreted to represent a sporophytic reduction series, with the operculate and peristomate members of Trematodon representing one end of the series and the cleistocarpous and smaller species of Bruchia the other evolutionary extreme. Throughout the family, species are defined primarily using sporophytic characters and they are rarely collected when sterile.
