Biologia reprodutiva e polinização de espécies simpátricas de Diplusodon (Lythraceae)
The reproductive biology and pollination of Diplusodon crulsianus Pohl, D. oblongus Pohl, D. ramosissimus Pohl, D. rosmarínifolius St. Hil, and D. villosus Pohl, were investigated during 1985, 1986 and 1 991. These species occur sympatrically in "cerrados" (savanna-like vegetation) of th...

| description | The reproductive biology and pollination of Diplusodon crulsianus Pohl, D. oblongus Pohl, D. ramosissimus Pohl, D. rosmarínifolius St. Hil, and D. villosus Pohl, were investigated during 1985, 1986 and 1 991. These species occur sympatrically in "cerrados" (savanna-like vegetation) of the Federal District (Brazil), where they flower synchronously, D. oblongus with D. villosus (January to April) and D. crulsianus with D. ramosissimus and D. rosmarínifolius (May to August). Differences in leaf morphology, presence or absence of tomentum on the vegetative and floral structures and stamen number, separate the species. Diplusodon flowers have diurnal anthesis, flowers are magenta-colored contrasting with the yellow stamens and show some degree of enantiostyly. Trigona spinipes L., Augochioropsis spp. and Apis mellifera L. were considered potential pollinators. Diplusodon species are xenogamous with facultativo autogamy in D. crulsianus and D. villosus (16% and 17 %). |

Diplusodon species are xenogamous with facultativo autogamy in D. crulsianus and D. villosus (16% and 17 %). La biología reproductiva y ia polinización de Diplusodon crulsianus Pohl, D. oblongus Poh!, D. ramosissimus Pohl, D. rosmarínifolius St.Hil, y D. villosus Pohl, fueron investigadas durante 1985, 1986 y 1991. Estas especies crecen simpatricamente en los "cerrados" del Distrito Federal (Brasil) y florecen sincrónicamente: D. oblongus con D. villosus y D. crulsianus con D. ramosissimus y D. rosmarínifolius. Diferencias en la morfología foliar, presencia o ausencia de pilosidad en las estructuras vegetativas y florales, y en el número de estambres, determinan la separación de las especies. Las flores de Diplusodon son productoras de polen, tienen antesis diurna, corola de color rosa fuerte, que contrasta con los estambres amarillos y muestran cierto grado de enantiostilia. Trigona spinipes L., Augochioropsis spp. y Apis mellifera L. se determinaron como polinizadores potenciales. Con relación a los sistemas reproductivos, las especies de Diplusodon son xenogámicas, ocurriendo autogamia facultativa en D. crulsianus y D. villosus (16 % y 17 %).
