MONIKA BARTH, Ortrud  and  FERNANDES PINTO DA LUZ, Cynthia. Pollen morphology of Vochysiaceae tree species in the State of Santa Catarina, Southern Brazil. Rev. biol. trop [online]. 2014, vol.62, n.3, pp.1209-1215. ISSN 0034-7744.

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. Trop. 62 (3): 1209-1215. Epub 2014 September 01.

Keywords : pollen grains; morphology; Callisthene; Qualea; Vochysia.
