bryo-

Moss.

Greek bruon, moss.

Bryology is the study of mosses and liverworts, small flowerless green plants called bryophytes that belong to the botanical division Bryophyta; Bryozoa (Greek zōia, animals) is a phylum of aquatic invertebrates that comprises the moss animals, sedentary colonial aquatic animals found chiefly in the sea. However, the name of bryony, the climbing Eurasian hedgerow plant, derives ultimately from the related Greek bruōnia, a wild vine.
