Floral polymorphism in Chamaecrista flexuosa (Fabaceae-Caesalpinioideae): a p…

† Background and Aims: Reciprocal herkogamy, including enantiostyly and heterostyly, involves reciprocity in the relative positions of the sexual elements within the flower. Such systems result in morphologically and, since pollen is deposited on and captured from different parts of the pollinator, functionally distinct floral forms. Deviations from the basic pattern may modify the function…
