Cormophyte

Very careful developmental or anatomical investigation may be required to show that the variously-constructed organs of many cormophytes are derived by the metamorphosis of the three primary organs, root, stem, and leaf, and to ascertain with which of these any particular structure is really homologous.

Botany used to recognize, if vaguely, these two kinds of plant, namely the thallophyte which grew and absorbed superficially, and the cormophyte, which is the root-shoot system with internal accommodation.

The morphology of cormophytes exhibits considerable variations in size, appearance of the various parts, and duration of the life cycle.
