''M. acuminata''. When the cultivated plants spread north-west into areas where ''M. balbisiana'' was native (see map), hybrids between the two species occurred and were then developed further into a wide range of cultivars. Hundreds of cultivars of ''M.'' × ''paradisiaca'' are known, possessing characteristics that are highly variable, but broadly intermediate between the ancestral species. They are typically tall when mature. The above-ground part of the plant is a "false stem" or

, consisting of leaves and their fused bases. Each pseudostem can produce a single flowering stem. After fruiting, the pseudostem dies, but offshoots may develop from the base of the plant. Cultivars of ''M.'' × ''paradisiaca'' are usually sterile, without seeds or viable pollen.

'' of 1705. ( plate 12). See also: At one time, to deal with the great diversity of cultivated bananas and plantains, botanists created many other names which are now regarded as synonyms of ''M.'' × ''paradisiaca'', such as ''M. corniculata'' Lour., used for a group of plantains with large fruit resembling the horns of a bull. Cultivated varieties are now given cultivar names, with the cultivars classified into groups and subgroups. Thus ''M.'' × ''paradisiaca'' 'Horn' is a cultivar belonging to the AAB genome group, Plantain subgroup. See
