The morphology and vascular anatomy of the flower in Melaleuca
fulgens R.Br.and Melaleuca nesophila F.Muell. (Ìyrtaceae) confirm the
hypothesis on the differentiation of axial vascular system in the myrtaceous
flower on the ascending vascular bundles in hypanthium and infralocular plexus.
Decreased flower size in Melaleuca nesophila is accompanied by the reduction of
the system of axial bundles, lateral sepal bundles and by the trend to
formation of stamen-petal vascular strands. There is no evidence for the
hypothesis of secondary polyandry in Myrtaceae. For the carpel vascularisation
is characteristic the reduction of carpel dorsals.
