Caricaceae

Papaya ( Carica papaya)

The melon tree plants ( Caricaceae ) are a plant family in the order of the Kreuzblütlerartigen ( Brassicales ).

Description

There are mostly small trees and shrubs, rarely herbaceous plants. The alternate, stalked leaves are lobed or compound.

The flowers appear singly or in zymösen inflorescences. The plants are monoecious monoecious or dioecious dioecious getrenntgeschlechtig. The unisexual flowers are radial symmetry and fünfzählig. There are five small sepals present. The five petals are fused; with a short tube in the female and a long in the male flowers. The male flowers contain one or two circles ( each) five fertile stamens; they are grown together freely in Carica or the other species at their base to a small tube, but they are always adherent to the corolla tube. In the female flowers five carpels are fused into a superior ovaries; there are one or five pens available, which may be partly covered, there are five scars present. Each ovary compartment contains 30 to 100 ovules.

The fruit is a berry.

Dissemination

The area of ​​the family is disjoint. The species are mainly in Central and South America, the so-called Neotropics, distributed; two types there are in Africa ( only in the genus Cylicomorpha ). A molecular phylogeny that includes all species is present ( Carvalho and Renner 2012).

System

In the family of Caricaceae there are six genera with about 34 species:

  • Melon trees ( Carica L.) with only one type: Carica papaya L.
  • Horovitzia cnidoscoloides ( Lorence & Torres) Badillo; it occurs in Mexico ( Oaxaca )
