Agave Agave (US: , UK: , , Anglo-Hispanic: ) is a genus of monocots native to the hot and arid regions of Mexico and the Southwestern United States. Some agave species are also native to tropical areas of South America. The plants are perennial, but each rosette flowers once and then dies (see semelparity). Some species are known by the name "century plant".
Paraspecies A paraspecies (a paraphyletic species) is a species, living or fossil, that gave rise to one or more daughter species without itself becoming extinct. Geographically widespread species that have given rise to one or more daughter species as peripheral isolates without themselves becoming extinct (i.e. through peripatric speciation) are examples of paraspecies.
