Resumo

The term ``seed pedestal{''} was introduced recently to describe a structure of placental origin connecting a seed with the placenta. Seed pedestals are widespread in Scrophulariaceae and a few adjacent families, but have not been found in Lentibulariaceae so far. Here their presence is reported for Utricularia reniformis from Brazil, and their formation during seed development is described. We observed that the formation of this structure was strictly associated with seed development; seed pedestals were not formed under aborted (unfertilized) ovules. (AU)
