The proportions of hermaphrodite to staminate flowers in inflorescences of the andromonoecious
species Caesalpinia 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.
