Pollen diversity in selected species of the tribe Chironieae (Gentianaceae Juss.) that occur in the Atlantic Forest, Brazil

ABSTRACT Based on molecular data, the tribe Chironieae (Gentianaceae) is divided into three subtribes. This study aims to describe the pollen morphology of representatives of two of the three subtribes that occur in the Atlantic Forest in order to contribute to a better understanding of the palynology of these taxa and to clarify the taxonomy of the family: subtribe Chironiinae (Centaurium erythraea and Zygostigma australe) and subtribe Coutoubeinae (Coutoubea ramosa, C. spicata, Deianira chiquitiana, D. damazioi, D. erubescens, D. nervosa and D. pallescens). Botanical material was obtained fr...
