ABSTRACT
Tropical Vochysiaceae includes mainly trees, and also shrubs and subshrubs. Three genera and seven species are present in the Brazilian state of Santa Catarina. The pollen morphology of six species of trees, belonging to three genera of the Vochysiaceae A. St-Hil. family, was studied. Herbaria samples were obtained, processed and treated by standard methods. The pollen grain morphology of Callisthene, Qualea and Vochysia is distinct. Medium sized pollen grains occur in Vochysia species, and small ones in Callisthene and Qualea. Specific characteristics were considered at species level [C. castellanosii H. F. Martins, C. kuhlmannii H. F.Martins, Qualea cordata Spreng var. cordata, Q. cryptantha (Spreng) Warm. var. cryptantha, Vochysia magnifica Warm. and V. tucanorum Mart.]. The presence of a fastigium (vestibulum) and a thin space devoid of nexine fixing the boundary of the apertural area is characteristic of Qualea and Vochysia species only. Rev. Biol.

RESUMEN
Las Vochysiaceae tropicales incluyen principalmente árboles, arbustos y subarbustos. Tres géneros y siete especies están presentes en el estado brasileño de Santa Catarina. La morfología del polen de las seis especies de árboles, pertenecientes a tres géneros de la Vochysiaceae A. St.- Hil . familia, fue considerado en el presente trabajo. La morfología de los granos de polen de Callisthene Mart., Qualea Aubl. y Vochysia (Aubl.) Juss. es distinta. Los granos de polen de tamaño medio se producen en las especies de Vochysia y pequeños en Callisthene y Qualea. Características particulares fueron considerados a nivel de especie [C. castellanosii H.F. Martins, C. kuhlmannii H.F. Martins, Qualea cordata Spreng var. cordata, Q. cryptantha (Spreng) Warm. var. cryptantha, Vochysia magnifica Warm. and V. tucanorum Mart.]. La presencia de un fastigium (vestibulum) y de un espacio delgado que carece de nexina limita la zona apertural y es característica solo de las especies de Qualea y Vochysia.
