Morphology
Description

Trees or shrubs, often poorly branched and pachycaul, rarely herbs or climbers , trunk occasionally covered in spines, often laticiferous , latex transparent or whitish. Stipules normally present, sometimes transformed in spines. Leaves generally petiolate , glabrous , generally with foetid or rank smell, venation generally palmate , entire to deeply dissected , sometimes digitate to trifoliolate , sometimes peltate (in Jarrilla Rusbydeltoid in outline), margin lobed , crenate or dentate , sometimes entire , base often cordate . Inflorescences axillary , cymose, racemose or paniculate, pedunculate or not, flowers sometimes solitary. Flowers hermaphrodite or unisexual in dioecious or polygamo- dioecious plants, hypogynous; calyx 5- merous , lobes free ; corolla 5- merous , lobes fused or free , white, cream or greenish; stamens 5-10, free or fused to the corolla and/or adnate, anthers dehiscing longitudinally; ovary superior , unilocular and with parietal placentation or 5-locular and then axile placentation, many-ovuled, style present, generally stout. Fruita large, green to orange, fleshy berry , indehiscent , many-seeded; seeds enveloped in mucilaginous pulp, testa verrucose , black, embryo straight, endosperm oily.

Distribution
Distribution in the Neotropics
  • Represented by three genera and over 30 species widely distributed in the Neotropics.
General Description
Number of genera
  • Carica L., 22 species throughout the Neotropics, poorly branched trees to shrubs (Carica papaya L. widely cultivated for its edible fruit).
  • Jacaratia A.DC., 6 species in arid regions of the Neotropics, pachycaul trees sometimes with spiny branches, leaves digitate.
  • Jarrilla heterophylla I.M.Johnst., 1 species only found in Mexico, herbaceous, decumbent.
General notes
  • Carica papaya is an important food crop, especially in Northeastern Brazil. This species has two types of plants: one with many-flowered inflorecences comprising staminate and pistillate flowers, that sometimes produce an elongated fruit, and the other with pistillate, sessile flowers, producing abundant rounded fruits, known as Papaya, Mamão (Braz.) and Fruta-Bomba (Caribbean).
Notes on delimitation
  • Together with the Brassicaceae, the Caricaceae is currently placed within order Brassicales alongside Tropaeolaceae (APGII, 2003, Souza & Lorenzi 2005).

Key to genera of Neotropical Caricaceae

1. Herbaceous, decumbent plants, with deltoid leaves .... Jarrilla
1. Shrubs or trees, self-supported, leaves never deltoid ... 2

2. Leaves entire to deeply lobed, branches smooth .... Carica
2. Leaves digitate to trifoliolate, branches often spiny.... Jacaratia

Distinguishing characters (always present)
  • Rank or foetid smell.
  • Mostly shrubby or tree -like.
  • Stamens didynamous.
  • Superiorovary with parietal placentation, stout style.
  • Large fruits with soft epicarp and succulentpericarp.
Key differences from similar families
  • Differs from Brassicaceae and Tropaeolaceae in woody, shrubby to tree-like habit.
  • From Araliaceae (similar due to its palmately compound leaves) in superiorovary and pentamerous flowers (vs. Araliaceae inferior ovary, tetramerous flowers).
  • From Bombacaceae (similar leaf shape and sometimes spinytrunk) in succulentindehiscentfruit (vs. Bombacaceae fruits which are dehiscent capsules with woolly seeds).
Other important characters
  • Spiny stems (sometimes).
  • Palmate leaves.
  • Latex present.
