The author proposes the term “hemerophytes” to include plants introduced by cultivation, as being more accurate than “anthropophytes.” These plants are divided into two main groups — (1) Apophytes, which have been introduced without direct human interference, and (2) Anthropochores, whose introduction is directly due to transport by man. Apophytes are classified according as they colonise cleared soil (kenapophytes), grass lands (leimonapophytes), cultivated fields (ergasiapophytes) and roadsides (chomapophytes, ruderal plants), or are cultivated indigenous plants (oikiophytes). Anthropochorous plants are divided into (a) those introduced unintentionally, including ephemerophytes (casuals), epoikophytes (colonists, aliens) and archaeophytes (naturalised plants), and (b) those introduced intentionally, including ergasiphytes (foreign cultivated plants) and ergasiphygophytes (escapes from cultivation). It is, however, recognised that a classification of this kind cannot be always applied strictly, and should not be pushed too far, since, for instance, a plant may be introduced in several of these ways.
