Haplomitriales is an order of plants known as Liverworts. The order is also called Calobryales in some sources, but the genus Calobryum is a synonym for Haplomitrium. Scientific classification or biological classification refers to how biologists group and categorize extinct and living species of organisms. ... Orders Anthocerales Haplomitriales Sphaerocarpales Marchantiales Metzgeriales Monocleales Calobryales Jungermanniales Takakiales Liverworts are non-vascular plants, also called hepatics. ... Calobryales is an order of plants known as Liverworts. ...
This order contains one family, Haplomitriaceae. Scientific classification or biological classification refers to how biologists group and categorize extinct and living species of organisms. ...
Another Devonian fossil called Protosalvinia also looks like a liverwort, but its relationship to other plants is still uncertain, so it may not belong to the Marchantiophyta.
The Jungermanniopsida includes primarily the two orders Metzgeriales (simple thalloids) and Jungermanniales (leafy liverworts), as well as a smaller orderHaplomitriales.
The Marchantiopsida includes primarily the orders Marchantiales (complex-thallus liverworts) and Sphaerocarpales (bottle hepatics), as well as the problematic genus Monoclea, which is sometimes placed in its own order Monocleales.
Two of these subgroups (Haplomitriales & Monocleales) each contain only one genus with two species each.
In this new classification, the Haplomitriales are part of the Metzgeriidae.
However, we have singled Haplomitrium out for a box of its own in the cladogram above, partly because of its unique combination of physical features and its traditionally separate status, but also because it may be the sister group (nearest relative) of the leafy liverworts (Jungermanniidae).
