Mosses, ferns such as filmy ferns, and liverworts grow luxuriantly. Their characteristic flora includes lush growth of ferns, mosses and liverworts. Mosses are commonly confused with hornworts, liverworts and lichens. The bryophytes, which include liverworts, hornworts and mosses, reproduce both sexually and vegetatively. It is home to exceptional epiphytic mosses, liverworts and lichens. In the bryophytes, including liverworts, hornworts and mosses, sex chromosomes are common. Glen Coe hosts several nationally scarce species of liverworts and mosses. All bryophytes, i.e. liverworts, mosses and hornworts, have the gametophyte generation as the most conspicuous. They include mosses, liverworts and hornworts. This gives Atlantic mosses, ferns, lichen, and liverworts the chance to grow. In the bryophytes (liverworts, mosses and hornworts), the sexual gametophyte is the dominant generation. Examples include the phyllids of mosses and liverworts. There are also the myco-heterotrophic "Monotropastrum humile", frequent liverworts, many mosses and many ferns. They also include the "bryophytes", of which mosses and liverworts are the most common. About 34% of the mosses and 19% of the liverworts are endemic.
