N2 - The aim of the present study is to describe the morphology and internal wall structure of Zingiber pollen. The pollen of 18 species of Zingiber was examined by light, scanning and transmission electron microscopy. In the sections Zingiber and Dymczewiczia (Horan.) Benth. the pollen grains are spherical with cerebroid sculpturing while in the section Cryptanthium Horan, the pollen is ellipsoid with spira-striate sculpturing. All species have a thin coherent exine and an intine consisting of a thick, radially channeled outer layer and a thin, finely granular inner layer. On the basis of pollen morphology it is proposed that the section Dymczewiezia is included in the section Zingiber. The structure of the pollen wall in Zingiber resembles that of Canna and Strelitzia in having a pollen wall offering an infinite number of germination sites.
