Carica

Carica is a genus of flowering plants in the family Caricaceae including the papaya (C. papaya syn. C. peltata, C. posoposa), a widely cultivated fruit tree native to the American tropics.
The genus was formerly treated as including about 20-25 species of short-lived evergreen pachycaul shrubs or small trees growing to 5–10 m tall, native to tropical Central and South America, but recent genetic evidence has resulted in all of these species other than C. papaya being reclassified into three other genera.
Taxonomy
The genus name comes from the botanical name of the fig, Ficus carica, because of the species' leaves or fruits resemble that of it. The carica epithet comes from Caria in southwest Anatolia (Asia Minor), Turkey, where the fig was mistakenly thought to have come from.
Species
According to World Flora Online, the genus Carica lists 21 species. Most of the other species have since been transferred to the genus Vasconcellea, with a few to the genera Jacaratia and Jarilla. According to the Catalogue of Life, the four remaining species in the genus are:
Carica aprica V. M. Badillo
Carica augusti Harms
Carica papaya L. (Papaya)
The species that have since been transferred to their new genera are as follows:
