Vegetative Multiplication.—Extensive experiments seem to indicate that every living cell of a moss-plant can develop protonemata—or in other words is a potential spore. These protonemata like those produced by the germination of spores, produce buds which may develop into mature plants. The production of entire plants or of parts of plants in this way, by portions of the vegetative body, is called regeneration. In some species of mosses the.
