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 Reboulia

Reboulia population at Enchanted Rock, Texas. Note archegoniophores.

Reboulia is a common liverwort on soil in central Texas. It often endures drought by curling and becoming dormant. When wet, it quickly uncurls and resumes growth. Reboulia bears antheridia and archegonia on the same thallus.
