Evolution of androecium development in Eugenia and related taxa. (A) Restricted androecium development, where stamen primordia appear just in the apical part of the hypanthium, leading to folded stamens in the bud. (B) Free androecium development, where stamen primordia cover the whole hypanthium tissue, leading to straight stamens in the bud. Stamens are shown in yellow and ‘empty’ hypanthial tissue in red. Other floral organs are kept the same size to help interpretation. (C) Reconstruction of stamen position in the bud on the Myrtaceae phylogeny. Arrow shows reversal to the plesiomorphic state in Myrcia, Plinia, Blepharocalyx and Myrceugenia groups. *The position of the Myrtus and Australasian groups are swapped in more recent phylogenies (Vasconcelos et al., 2017b)
