Reproductive Phytochemistry of Bombacaceae

Abstract

Floral anthocyanins among Bombacaceae exhi6it minimal variation and consist of three commonly occurring cyanidin glycosides. Cyanidin 3-rutinoside occurs uniquely in the genus Pachira among taxa surveyed. Nectars are characterized by copious volumes and being somewhat dilute and hexose rich with respect to sugars. No evidence is detectable among Bombacaceae for a nonfiying-mammal floral chemistry syndrome which is distinguishable from a bat-visitation syndrome.
