Abstract

Data on pollen aperture and wall ultrastructure are reviewed for the monocots. New ultrastructural data on 30 taxa representing 18 monocot families are also presented. The evolutionary trends of apertures and pollen wall structure are discussed and it is proposed that the evolutionary trends of pollen apertures and wall structure in the monocots parallel those proposed by Walker for the dicots. However, the importance of these trends differ for monocots, suggesting that the selective pressures affecting pollen wall and aperture evolution in dicots and monocots have been similar, but with different emphasis.
