Abstract

This work describes pollen grains from the species of Hernandiaceae (Sparattanthelium), Monimiaceae (Mollinedia), and Siparunaceae (Siparuna) from a 100 km2 area, Reserva Florestal Adolpho Ducke (03º00'00''S – 59º52'40''W) in the municipality of Manaus, Amazonas, aiming to supply taxonomic studies in Laurales. Pollen material was included in the Amazon Palynogical Database as a reference for other studies. The pollen analysis in light microscopy (LM) and Scanning Eletronic Microscopy (SEM) include the species Sparattanthelium acreanum Pilg., Mollinedia ovata Ruiz & Pav., Siparuna cristata (Poepp. & Endl.) A. DC., S. depressa Jangoux, S. ficoides S.S. Renner & Hausner, S. guianensis Aubl., and S. poeppigii (Tul.) A. DC. The pollen of Mollinedia ovata is ellipsoidal, catazonasulculate, and rugulate, unlike the pollen of other species. In Sparattanthelium acreanum and in the five species of Siparuna, the grains appear spheroidal, inaperturate, microechinate, and very uniform in LM, however, details in the ornamentation that allow taxonomical separation are visible by SEM. The results reinforce taxonomic distinction among the three involved families of Laurales and shown importance of SEM in the separation of species.
