A study was conducted on Mangifera casturi, Mangifera lalijiwa, Mangifera rubrapatela, Mangifera odorata, Mangifera sp. 'Tenom', Mangifera zeylanica, and Mangifera sp. 'Rampagni' grown at the Fairchild Tropical Botanic Garden living collection located in Homestead, FL, USA. These species are part of a Mangifera species collection that currently consists of 40 accessions collected from or native to Brunei Darussalem, Cambodia, Indonesia, Malaysia, Thailand, and the Philippines. There exists limited information on bloom morphology of wild mango relatives, and most information in the literature was derived from herbarium specimens. Information collected includes color, petal number, hermaphrodite/male ratio, aroma, and panicle architecture. The study was conducted from 2012 to 2015. Evaluations of flower morphology were done during January to May. Inflorescences were randomly selected from each tree, photographed and drawn for evaluation of flowering morphology structure of the seven species. In terms of floral morphology, they all have differing percentages of hermaphrodite and male flowers; have four to six petals; range in color from cream to white, burgundy and red; have aromas from lilacs to jasmine; and show variable panicle branching patterns. M. casturi, M. lalijiwa, M. rubrapetala, M. zeylanica and Mangifera sp. 'Tenom' have more hermaphrodite flowers than M. odorata and Mangifera sp. 'Rampagni'. Hermaphrodite to male ratios were greater in these two species in both years. The relationship between hermaphrodite and male flowers is discussed, as well as the ramifications for breeding and fitness as parents for crosses with Mangifera indica.
