Text-fig. 46. Scanning electron microscope (SEM) images of monocolpate pollen of Teebacia hughesii gen. et sp. nov. pollen from a stamen fragment; Torres Vedras locality, Portugal. a) Holotype; stamen fragment showing elongated pollen sacs that yielded the pollen in this Text-figure (d, e); b) Detail of detached reticulum showing inner surface of muri and scattered columellae; note the finely granular covering of the muri and columellae; c, d) Detail of reticulum showing the outer surface of muri with supratectal ornamentation of narrow ridges; note orbicules attached to the reticulum (d); e, f) Pollen grains showing loose, beaded, reticulum with long columellae; note continuous muri bordering the apertures and densely spaced minute orbicules lining the inner surface of the anther wall (e, arrowheads).
