6; see text Mora is a genus of large trees in the subfamily Caesalpinioideae[2] of the legume family Fabaceae (or in some classifications the family Caesalpinaceae of the order Fabales).

There are six species, all native to lowland rainforests in northern South America, southern Central America, the southern Caribbean islands, and Hispaniola.

[3] The genus is particularly noteworthy for the exceptional size of its beans, which are commonly acknowledged to be the largest known dicot seeds, in the instance of M. oleifera being up to seven inches (18 cm) in length, six inches (15 cm) in breadth and three inches (7.6 cm)in thickness,[4][5] and a weight of up to 2.2 pounds (1,000 grams).

[6] These very large beans develop out of tiny flowers with a pistil only one millimeter wide [7] involving a growth of over 2,000,000 fold.

The species M. excelsa is one of the few rainforest trees to grow in pure stands.
