GONCALVES-ESTEVES, VANIA  and  MENDONCA, CLAUDIA BARBIERI FERREIRA. Polinic study in plants from "restinga" in the state of Rio de Janeiro: Clusiaceae Lindl. Rev. bras. Bot. [online]. 2001, vol.24, n.4, suppl., pp.527-536. ISSN 0100-8404.

This work deals with the palylonogy of eight species of Clusiaceae: Calophyllum brasiliense Cambess., Clusia criuva Cambess., C. hilariana Schltdl., C. lanceolata Cambess., C. parviflora (Sald.) Engl., Garcinia brasiliensis Mart., Kielmeyera membranacea Casar. e Symphonia globulifera L.f. The pollen material was acetolysed, measured, described and illustrated with photo or eletronmicrography (SEM). The main features of the pollen grains were studied: shape, size, exine constitution and aperture type. The pollen grains of Clusiaceae were small, medium or large in size, suboblate, oblate-spheroidal, prolate-spheroidal or subprolate, isopolar, porate (3-6) or 3-colporate, very small, small or large polar area, with rugulate or reticulate exine. It is concluded that the genera and the species can be separated by palynological characters, constituting an euripalynous group.

Keywords : Palynology; Clusiaceae; restinga; pollen.
