The Kapok, Silk Cotton or Ceibo Tree (Ceiba pentandra)
One of several species of the genus
Ceiba, the kapok tree, a.k.a. the silk-cotton tree or
ceibo, produces conspicuous white flowers only at night that attract pollinating bats or moths, depending on the species.
Ceibas grow along edges, river banks, and in disturbed areas, which make them one of the rainforest’s most widespread trees. The smooth, gray trunk often reaches 50 m/164 ft high before spreading into a flattened or rounded crown, and the major branches radiating horizontally from the trunk are usually covered with epiphytes, such as orchids and bromeliads, as well as vines.
Although the
Ceiba pentandra flowers infrequently, it is capable of producing 500-4000 fruits, each with approximately 200 seeds. The seeds are contained in oval fruits that open on the tree, and each seed is surrounded by silky, cotton-like fibers called kapok that aid in wind dispersing the seeds.
The fiber is used by the Huaorani to fletch their blowgun darts, and continues to be used in more modern industry for stuffing pillows, mattresses and teddy bears as well as for acoustical insulation since it has low thermal conductivity. Once upon a time it was the stuffing of choice for life preservers as it is buoyant and impervious to water, but has since been replaced by man-made materials.
