Name

Castilla Cerv.

Castilla (sometimes incorrectly spelled Castilloa) is a genus of 3 species of large trees in the flowering plant family Moraceae. The genus is native to Central and South America.[1]

Etymology

This genus is named after Juan Diego del Castillo (d. 1793), a Spanish botanist who was a friend of Vicente Cervantes, who chose the name in his friend's honor.[2][3]
Description

Castilla species are monoecious or dioecious trees up to 40 meters tall, with buttressed trunks and abundant white latex of commercial value.[1] The branchlets have scars left by the fallen stipules. The leaves are oblong to elliptic, with entire margins.[1][4] The inflorescences are surrounded by bracts and have small flowers. The male flowers are borne in lengthwise-folded kidney-shaped inflorescences and female flowers in globose inflorescences.[1][4] The infrutescence varies in shape and has orange or red fruits.[1]

Castilla species exhibit a phenomenon known as cladoptosis, the regular shedding of branches. This may be an adaptation to prevent the growth of climbing plants.[5]

Castilla elastica is a weedy tree which has become invasive in areas where it has been introduced, such as in Tanzania and the South Pacific.[4][6]
Uses

The main species is Castilla elastica, one of several plants from which rubber has been extracted. The vernacular name is Panama rubber tree or castilloa rubber. The pre-Columbian MesoAmericans used the latex of this plant to make a ball used in a ceremonial game.
