Abstract

This paper studied the pollen morphology of 12 species of Cestrum, C. amictum Schltdl., C. coriaceum Miers, C. laevigatum Schltdl., C. lanceolatum Schott ex Sendtn., C. martii Sendtn., C. megalophyllum Dunal, C. parqui L`Hér., C. retrofractum Dunal, C. salzmannii Dunal, C. schlechtendahlii G. Don, C. sendtenerianum Mart. ex Sendtn and C. viminale Sendtn.. The studied specimen was collected in the hygrophilous forest of Bahia State. The polliniferous material was acetolyzed and the pollen grains were examined in light microscope. The pollen grains were medium sized, but their size range varied from 20,0 to 50,0µm, oblate spheroidal to subprolate 3-colporate. Three basic pollen types were observed considering the ornamentation: perforate-scabraye, verrucate and striate. These analyzed data may be useful to taxonomical identification of the studied species of Cestrum
