The majority of angiosperms (~94 %) are synoecious, with only a small minority separating the production of the two gamete types onto different biological individuals (dioecy). For many plant species, however, reproductive systems and habits are not well documented. This is particularly true of tropical trees, which, despite their conspicuity, are poorly understood. Plants in the genus Triplaris have been consistently described as strictly dioecious. After morphologic analysis using a dissecting microscope, here I present a number of fully-formed perfect (hermaphroditic) flowers observed on Triplaris herbaria specimens.

La mayoría de las angiospermas (~94 %) son sinóicas, y sólo una pequeña minoría separa la producción de los dos tipos de gametos en distintos individuos biológicos (dioica). Sin embargo, los sistemas y hábitos reproductivos de muchas especies vegetales no están bien documentados. Esto es particularmente cierto en el caso de los árboles tropicales, que, a pesar de su conspicuidad, son poco conocidos. Las plantas del género Triplaris han sido descritas sistemáticamente como estrictamente dioicas. Luego del estudio morfológico utilizando un microscopio de disección, presento la observación de un número de flores perfectas (hermafroditas) completamente formadas observadas en especímenes de herbario pertenecientes al género Triplaris.
