Palm pollen Scanning Electron Micrographs by Gwen Haaland. Fig 94-96 Ceroxylon quindivense an extant beetle pollinated Ceroxyloid palm. Fig 94. SEM of monosulcate coarsely reticulate pollen grains X 3,240. Fig. 95 High mag SEM of exine ornamentation. Diameter of the lumina decreases towards the margins X 7,810. Fig 96 Note finely gemmate infratectal ornamentation X9,010.

Monocot Pollen Grains: Scanning electron micrograph​s of pollen grains from Iriartea ventricosa, an extant bee-pollin​ated palm. Pollen is clavate and intectate (lacks a roof-like layer. Fig 27. X 2,500. Fig 28. SEM of the pollen exine showing the size and shape of the clavae, which create a highly uneven surface X9,990.
