Resumo: The ovule ontogenesis and the megasporogenesis events were studied under bright field, fluorescence and scanning electron microscopy. The primordium is 3-zonate and gives rise to a hemianatropous, bitegmic and crassinucellate ovule. The archesporium may consist of one or more archesporial cells, but only one undergoes meiosis, forming a linear tetrad. Normally, only a single megaspore is functional in the chalazal position, but occasionally two functional chalazal megaspores arise. The present study provides additional information on embryological characters in the Adesmieae tribe and discusses their taxonomic significance to the Leguminosae family.
