A family of tropical trees that includes the kapok tree, known for their large flowers and fiber-producing seed pods.
From Latin 'bombax' (cotton tree) combined with the taxonomic suffix '-aceae' (plant family), ultimately derived from Arabic 'bambak' (cotton). The term was formalized in botanical nomenclature during the 18th century.
The kapok tree from this family produces silky fibers so buoyant they're used in life jackets and mattresses—a natural material that can keep people literally afloat!
