Zea (genus)
''Zea'' is a genus of plants in the grass family. The best-known species is ''Z. mays'', variously called maize, corn, or Indian corn, one of the most important crops for human societies over much of the world. Several wild species are commonly known as teosintes and are native to Mesoamerica.
==Recognized species==
The five recognized species in the genus are: ''Zea diploperennis'', ''Zea perennis'', ''Zea luxurians'', ''Zea nicaraguensis'', and ''Zea mays''. The last species is further divided into four subspecies: ''Z. m. huehuetenangensis'', ''Z. m. mexicana'', ''Z. m. parviglumis'', and ''Z. m. mays''. The first three subspecies are teosintes; the last is maize, or corn, the only domesticated taxon in the genus ''Zea''. The species are grouped into two sections, section ''Luxuriantes'', with the first four species, and section ''Zea'' with ''Zea mays''. The former section is typified by dark-staining knobs made up of heterochromatin that are terminal on most chromosome arms, while most subspecies of section ''Zea'' may have none to three knobs between each chromosome end and the centromere and very few terminal knobs (except ''Z. m. huehuetenangensis'', which has many large terminal knobs). The two perennials are thought to be one species by some.
