Castilla elastica Castilla elastica Castilla elastica, the Panama rubber tree, is a tree native to the tropical areas of Mexico, Central America, and northern South America. It was the principal source of latex among the Mesoamerican peoples in pre-Columbian times. The latex gathered from "Castilla elastica" was converted into usable rubber by mixing the latex with the juice of the morning glory species "Ipomoea alba" which, conveniently, is typically found in the wild as a vine climbing "Castilla elastica". The rubber produced by this method found several uses, including most notably, the manufacture of balls for the Mesoamerican ballgame "ōllamaliztli". The Aztec
Site of Ficus superba var. henneana tree a multi-stemmed specimen with stems straddling the site and adjacent properties. The combined trunk diameter exceeds . It is a young and healthy tree, considered against the maximum potential life expectancy for this genus. Based on the synconium being in pairs, the relatively-small size of fruit and presence of a drip tip (to the leaf) there is a reasonable likelihood that the earlier identification (of Ficus superba var.henneana) is now incorrect. Based on the features observed at the two inspections, it would appear that the tree is a white fig, "Ficus virens", probably planted after the first (colonial) settlement in
