Genipa americana (Huito or Jagua) is a species of Genipa, native to northern South America (south to Peru), the Caribbean and southern Mexico, growing in rainforests. It is a small tree growing to 15 m tall. The leaves are opposite, lanceolate to oblong, 20-35 cm long and 10-19 cm broad, glossy dark green, with an entire margin. The flowers are white, yellow or red, with a five-lobed corolla 5-6 cm diameter. The fruit is a thick-skinned edible berry 5-8 cm diameter.

A number of infraspecific taxa have been described:

  • Genipa americana var. americana
    • Genipa americana f. grandifolia Chodat & Hassl.
    • Genipa americana f. jorgensenii Steyerm.
    • Genipa americana f. parvifolia Chodat & Hassl.
  • Genipa americana var. caruto K.Schum.
  • Genipa americana var. riobranquensis Kuhlm.

The leaves are a food source for the caterpillars of the Fadus Sphinx Moth (Aellopos fadus).

[edit] Uses

Genipa americana is cultivated for its edible fruit, which are made into drinks, jelly, sherbet and used in ice cream. It is also useful for treatment of candiru attacks. South American Indians bathe their legs in the clear liquid obtained from the fruit. The liquid has a stringent effect. Furthermore it stains the skin black. These stains disappear after about a fortnight. As South Americans Indians went into battle, they used to paint themselves with Genipa juice and annatto.

The juice of the immature fruit is clear, but induces a chemical reaction on the human skin resulting in a nice tattoo-like dark blue. Used by rainforest natives as body-painting color. The ripened fruit of Huito is often eaten raw or made into jam. The fruit is brewed into a tea and taken as a remedy for bronchitis. Huito prefers alluvial soils, and grows very quickly (producing in 3 years), even in heavily flooded fields. This tree can be planted but more often than not it is dispersed by animals or water. It also serves as a very good climbing tree to reach other trees.
