Evergreen Wood Fern
[EXPLANATION OF TERMS]

A rootstock is an underground, rooting stem. Ferns are propagated by the growth and budding of the rootstock as well as by the ordinary method of reproduction. The fronds spring from the rootstock in the manner peculiar to the species to which they belong. The Osmundas, the Evergreen Wood Fern, and others grow in a crown or circle, the younger fronds always inside. The Mountain Spleenwort is one of a class which has irregularly clustered fronds. The fronds of the Brake are more or less solitary, rising from distinct and somewhat distant portions of the rootstock. The Botrychiums usually give birth to a single frond each season, the base of the stalk containing the bud for the succeeding year.
