TEXAS BRYOPHYTE IMAGE GALLERY

The identification of bryophytes typically requires the microscopic examination of leaves, stems, spores, etc.  However, for the amateur bryologist the availability of microscopes and other tools may be limited.  To aid the user in some very basic identification, a dichotomous key to the three groups of bryophytes is provided below.  The links in the key will direct the user to selected photographs of bryophytes found in Texas.  Or, alternatively (if you are averse to using a key) you can select one of the groups below and go straight to the image galley for that group.

This image gallery is a work in progress, so check back as content is added.

A dichotomous key to the groups of bryophytes in Texas

Plants thalloid  

      Thallus with a single, large chloroplast occupying the majority of the lumen in each cell - ANTHOCEROTOPHYTA (hornworts)

      Thallus with multiple chloroplasts; or if with a single chloroplast, then individual chloroplasts small and not occupying the majority

      of the lumen in each cell - MARCHANTIOPHYTA (thalloid liverworts)

 Plants leafy

      Leaves with one or more oil bodies present in most cells - MARCHANTIOPHYTA (leafy liverworts)

      Leaves without oil bodies

            Leaves costate - BRYOPHYTA (mosses)

            Leaves ecostate

                  Leaves spirally arranged on stem - BRYOPHYTA (mosses)

                  Leaves distichously arranged on stem - MARCHANTIOPHYTA (leafy liverworts)
