Marchantia polymorpha : Taxonomy, Phylogeny and Morphology of a Model System

Liverworts Marchantiophyta , including Marchantia , occupy a pivotal position in land plant phylogeny and are thus useful for exploring the diversity and universality of various biological phenomena from an evolutionary viewpoint. Few existing specimens and the description do not support the taxonomic status of these names ,. Upper two cells of the four celled filament are known as primary antheridial cells and lower two cells are known as primary stalk cells Fig.
