Since the first edition of Carl Linnaeus's Species Plantarum in 1753, plants have been assigned one epithet or name for their species and one name for their genus, a grouping of related species. Related genera are in turn grouped into families. Each family's formal name ends in the Latin suffix -aceae and is derived from the name of a genus that is or once was part of the family.
LG: derived from a Greek word (G), a Latin word (L), another language (–), or a personal name (P)

Linked numerical citations in the last column refer to Plants of the World.
Except for Plants of the World, these books list genera alphabetically. "Latin plant name" or "Greek plant name" in the fourth column means that the name appears in Classical Latin or Greek or both for some plant, not necessarily the plant listed here.
