dc:description"Text-fig. 25. Scanning electron microscope (SEM) images of stamens and pollen grains of Elasmostemon paisii gen. et sp. nov.; Catefica locality, Portugal. a) Stamen fragment showing two pairs of pollen sacs along the margins of the stamen with a broad connective that separates the thecae, except near the apex where the thecae meet; b) Detail of surface of pollen sacs showing larger cells (arrows), interpreted as ethereal oil cells; c) Pollen in situ from specimen in (a); d) Stamen fragment with apical and basal portion missing and surface slightly abraded and compressed obscuring cellular details; note remains of another stamen attached to the underside of the stamen; e–h) Pollen in situ from specimen in (d) showing long aperture (e) and pollen wall with heterobrochate reticulum (e–h); note narrow muri with flatten and smooth surface and short columellae (h). Specimens, Catefica 49-S115859 (a–c), Catefica 151-S105281 (holotype, d–h). Scale bars = 600 Μm (a, d), 50 Μm (b), 6 Μm (c, e–g), 1.5 Μm (h).";
dc:description"Text-fig. 26. Scanning electron microscope (SEM) images of stamens and pollen grains of Elasmostemon paisii gen. et sp. nov. (a–c) and laminar stamens with monocolpate reticulate pollen sp. (d–g); Catefica locality, Portugal. a) Stamen fragment with basal portion missing showing two pairs of pollen sacs on one surface of the stamen close to the margin and separated by a broad connective, except near the apex where the thecae meet; note that the thecae are dehisced with the walls of the pollen sacs curled back; b) Pollen grains inside a dehisced pollen sac; note variation in size and development of the reticulum; c) Detail of (b) showing monocolpate, reticulate pollen with lumen of reticulum varying markedly in size but partly obscured by residual organic material; d) Stamen with apical and basal part of anther preserved showing two pairs of pollen sacs (asterisks) on the curved, perhaps ventral, surface close to the stamen margin; e) Detail of crack in the anther showing the inner anther wall with densely spaced spherical orbicules that vary greatly in size; f) Pollen exposed in the crack in the anther; note coarsely foveolate to coarsely reticulate pollen wall and densely spaced orbicules; g) Folded pollen grains with reticulate pollen wall and also showing the inner anther wall with densely spaced spherical orbicules that vary greatly in size. Specimens, Catefica 49-S172560 (a–c), Catefica 50- S170384 (d–g). Scale bars = 600 Μm (a, d), 20 Μm (b, e), 6 Μm (c, f, g).";
