Mosses could not transport water within their bodies. Mosses did not even engage in sex. (Or at least they did not engage in sex in any obvious manner, unlike lilies or apple blossoms—or any other flower, in fact—with their overt displays of male and female organs.) Mosses kept their propagation a mystery to the naked human eye. For that reason, they were also known by the evocative name Cryptogamae—“hidden marriage.”
