(Metzgeriaceae, Metzgeriales), Frullania Raddi (Frullaniaceae, Jungemanniales) and Stephaniella J.
The Metzgeriales species are usually "thalloid plants"; the thallus has a thick and flattened central midrib and thinner lateral wings undivided or more or less dissected into lobes.
While the sister clade is sister includes the "true" leafy liverworts and small group of simple thalloids belonging to the Metzgeriales. In this scheme Pleurozia with decidedly nodal anatomy and classically thought of as a leafy liverwort is shown to be allied to the Metzgeriales.
Although Farmer did not report premeiotic bands, perhaps due to limits of resolution, he did however comment on the lack of observable asters that are so prevalent in the members of the Metzgeriales. Modern studies of two species of leafy liverworts have shown that cytoplasmic quadrilobing of pre-meiotic sporocytes into future spore domains is initiated by girdling bands of microtubules and confirmed the curious lack of asters/POs.
