A medium-to-large-sized tree, with a trunk covered with spines, the cotton tree, Ceiba acuminata, grows in Baja California and the western part of Mexico.

The fruit is a thick pod up to four inches (10 centimeters) long containing brownish or nearly white cotton in which is embedded small black seeds.  The cotton is used for stuffing pillows and for candlewicks and the seeds furnish a durable "bead" for necklaces.  It is a Mayan belief that the route to the afterlife is accessed through the Ceiba tree.3
