The proportions of hermaphrodite to staminate flowers in inflorescences of the andromonoecious species Caesalpinb calycina vary. Analysis of fruit position along the flowering rhachis, and also of the sex of floral buds in inflorescences with fruits set in different positions, indicate that fruiting success influences the sex of flowers in distal positions along the rhachis. Other reports of andromonoecy in caesalpinoid species are examined with reference to floral sex lability and the influence of fruit set.
