- Ultrastructure and pollen morphology of Bromeliaceae species from the Atlantic Rainforest in Southeastern Brazil VANESSA J.D. SILVA ESTER M. RIBEIRO ANDREA P. LUIZI-PONZO ANA PAULA G. FARIA Multidisciplinaria (Ciencias Naturales y Exactas) taxonomy Epiphytes morphology pollen grains Pollen grain morphology of Bromeliaceae speciescollected in areas of the Atlantic Rainforest of southeastern Brazilwas studied. The following species were analyzed: Aechmea bambusoides L.B.Sm. & Reitz, A. nudicaulis (L.) Griseb., A. ramosa Mart. exSchult.f., Ananas bracteatus (Lindl.) Schult.f., Billbergia distachia (Vell.) Mez, B. euphemiae E. Morren, B. horrida Regel, B. zebrina (Herb.) Lindl., Portea petropolitana (Wawra) Mez, Pitcairnia fl ammea Lindl., Quesnelia indecora Mez, Tillandsia polystachia (L.) L., T. stricta Sol., T. gardneri Lindl., T. geminifl ora Brongn. and Vriesea grandifl ora Leme. Light and scanning electron microscopy were used and the species were grouped into three pollen types, organized according to aperture characteristics: Type I – pantoporate pollen grains observed in P. petropolitana, Type II – 2-porate pollen grains, observed in the genera Ananas, Aechmea and Quesnelia,and Type III – 1-colpate pollen grains, observed in the genera Billbergia, Pitcairnia, Tillandsia and Vriesea. Pollen data led to the construction of an identifi cation key. The results showed that the species analyzed can be distinguished using mainly aperture features and exine ornamentation, and that these characteristics may assist in taxonomic studies of the family. 2016 artículo científico 0001-3765 https://www.redalyc.org/articulo.oa?id=32746362002 en http://www.redalyc.org/revista.oa?id=327 Anais da Academia Brasileira de Ciências application/pdf Academia Brasileira de Ciências Anais da Academia Brasileira de Ciências (Brasil) Num.1 Vol.88
