MOSSES AND ALLIES

"The mosses, liverworts, and hornworts are relatively small plants, many less than 2 cm long and most less than 20. When clumped together, they can be conspicuous components of forest and other habitats. Traditionally these three divisions have been grouped together as the bryophytes. Recent research has confirmed, however, that they are quite distinct, especially the hornworts. Although they are often abundant in relatively moist areas all over the world, many can remain alive for years in a dry condition, recovering quickly if moistened."
