Text-fig. 41. Scanning electron microscope (SEM) images of monocolpate pollen of Piercipollis simplex gen. et sp. nov. from a pollen clump; Torres Vedras locality, Portugal. a) Holotype; pollen clump that yielded the pollen in this Text-figure; b–d) Pollen grains in distal (b), proximal (c) and lateral views (d) showing the very long colpus and the well-developed reticulum that is only loosely attached to the smooth surface of the foot layer; note the large angular lumina, smooth muri and short, sparsely scattered, columellae; note also that main body of pollen grains (foot layer) does not fill out the whole space of the reticulum; e) Reticulum showing the smooth muri loosely attached to the smooth surface of the foot layer by short, sparsely scattered, columellae. Specimen, TV44-S136755 (holotype). Scale bars 300 Μm (a), 6 Μm (b–d), 3 Μm (e). in The Early Cretaceous Mesofossil Flora Of Torres Vedras (Ne Of Forte Da Forca), Portugal: A Palaeofloristic Analysis Of An Early Angiosperm Community
