Phylum Hepatophyta -- liverworts Hepatophyta, along with Bryophyta and Anthocerotophyta are sometimes jointly called "bryophytes" since earlier classification systems placed them in a single phylum. All three of these phyla are said to have the gametophyte generation as the "dominant" generation. In central Texas, large liverworts are fairly common on moist, rocky slopes, on moist tree-trunks, and on boulders in shallow streams. Smaller liverworts are common on soil and tree-trunks. Genus Marchantia

Marchantia antheridiophores (central Texas population)

Marchantia domingensis is the most commonly encountered species of Marchantia in central Texas. Most teaching labs utilize M. polymorpha.

Marchantia archegoniophores- from one population in central Texas

M. domingensis archegoniophores exhibit a range of size and shape when growing wild. Many central Texas populations are entirely female.

Marchantia polymorpha antheridiophore	Marchantia bears antheridia and archegonia on separate thalli.
