Discussion
R. A. DeFilipps (1968, 1969) recognized three varieties of Ximenia americana, with the pantropical var. americana occurring in peninsular Florida. The other varieties occur in Argentina (var. argentinensis DeFilipps) and Africa (var. microphylla Welwitsch ex Oliver). From greenhouse pot studies, DeFilipps (1969b) determined that X. americana is able to exist without a host, thus it should be considered a facultative hemiparasite. The flowers are fragrant and presumably insect pollinated. The anthers dehisce before the flower bud opens and the adaxial hairs on the petals may serve to present the pollen (P. B. Tomlinson 1980). Variety americana shows different growth forms on different substrates; plants on sandy coastal areas are sprawling shrubs with orbiculate, fleshy leaves, whereas plants in forests and scrublands are trees with oblong to oblanceolate, thin leaves.
Ximenia inermis Linnaeus, an illegitimate and superfluous name, pertains here.
