Cecropias

Cecropias are a genus of trees belonging to the family Urticaceae, commonly known as the stinging nettle family. These trees are native to the Neotropics, found from Mexico south to Argentina. They are fast-growing, pioneer species, often colonizing disturbed areas like roadsides, landslides, and cleared forests. Cecropias are easily recognizable by their large, palmately lobed leaves and their distinctive hollow stems. These stems are often inhabited by Azteca ants, with which the trees have a mutualistic relationship. The ants protect the tree from herbivores and competing vegetation, while the tree provides shelter and food for the ants in the form of Beltian bodies.

Several species are commonly found, with Cecropia obtusifolia and Cecropia peltata being widespread. The trees typically have a slender, upright growth habit, rarely exceeding 20 meters in height. Their leaves are a prominent feature, often reaching up to 60 centimeters in diameter, and are a food source for various animals, including sloths and certain insects. The fruit of the Cecropia is a small, fleshy drupe, borne in clusters. In some regions, Cecropia wood is used for light construction, firewood, and in the production of paper. Their rapid growth and ability to thrive in open, sunny conditions make them important for ecological regeneration in tropical ecosystems. The genus name, Cecropia, is derived from Cecrops, a mythical king of Athens.
