Morphology of Mosses (Phylum Bryophyta)

The other two phyla are Marchantiophyta or liverworts and Anthocerotophyta or hornworts. The term “bryophytes” is a general, inclusive term for these three groups though they are only superficially related. Mosses are widely distributed from...

متن کاملGuidelines for the Use of Native Mosses
These guidelines on the use of mosses are of strategic importance in that they make it possible to harmonize the indications obtained from differing environments in terms of extent and, thereby, to compare them with results obtained using other methods. Thanks to their morphological features, mosses can be used as bioindicators to obtain fallout information for a significant number of organic a...
