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.
Description
Castilla species are monoecious or dioecious trees up to 40 meters tall, with butressed trunks and abundant white latex of commercial value. The branchlets have scars left by the fallen stipules. The leaves are oblong to elliptic, with entire margins. 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. The infrutescence varies in shape and has orange or red fruits.
Ecology
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.
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.
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.
