Hémérochorie
thumb|300px|Le coquelicot est une plante hémérochore, classée parmi les archéophytes. Sa splendeur écarlate remplace ici l'or des fleurs du champ de colza qui sont fanées. Par hémérochorie, on entend – surtout en Europe – la diffusion des plantes par la culture. On utilise souvent le synonyme anthropochorie, en assimilant la culture à l’action de l'humain.
Archaeophyte
An archaeophyte is a plant species which is non-native to a geographical region, but which was an introduced species in "ancient" times, rather than being a modern introduction. Those arriving after are called neophytes. The cut-off date is usually the beginning of the early modern period (turn of the 15th or 16th century). In Britain, archaeophytes are considered to be those species first introduced prior to the year 1492, when Christopher Columbus arrived in the New World and the Columbian Exchange began.
Escaped plant
Escaped plants are cultivated plants, usually garden plants, that are not originally native to an area, and due to their dispersal strategies, have escaped from cultivation and have settled in the wild and bred there, whether intentionally or unintentionally. Escaped plants are purposefully introduced plants that have naturalized in the wild and can develop into invasive plants, the settlement of which is to be assessed as problematic. Other commonly used terms include escaped garden plant, garden escapee, escaped ornamental or garden refugee.
Adventive plant
Adventive plants or adventitious plants are plants that have established themselves in a place that does not correspond to their area of origin due to anthropogenic influence and, therefore, are all wild species that have only been established with the help of humans, in contrast to the native species. The term "adventive" is used to describe species that are not self-sufficient, but need an episodic population assistance from their homeland. If, however, an adventive species becomes self-sustaining in its new geographic area, it is then naturalized.
Espèce introduite

On qualifie d'espèce introduite une population identifiée/isolée d'une espèce donnée -- qu'elle soit présente ou maintenue présente artificiellement (espèces domestiquées, espèces « adventives ») en cours de naturalisation ou déjà naturalisée -- dans un territoire donnée, considérant qu'elle n'est pas une espèce indigène dudit territoire mais y a été importée par une intervention humaine (délibérée ou non).
