Text-fig. 23. Synchrotron radiation X-ray tomographic microscopy (SRXTM) images of Ibericarpus cuneiformis gen. et sp. nov.; Catefica locality, Portugal. a) Longitudinal section (orthoslice yz0827) showing fruitlet with apical stigmatic region and a single seed enclosed within the fruitlet wall that has a thick epidermal cuticle; note the tiny embryo (emb) internal to the micropyle (mi) and oriented toward the base of the fruitlet; b) Transverse section through apical part of two fruitlets (orthoslice xy0810) showing the fruitlet wall (fr) composed of small thin-walled cells covered by an epidermis of isodiametric cells (ep) with a thick outer cuticle (cu); c) Longitudinal section (orthoslice xz0370) through basal part of fruitlet perpendicular to section in (a) showing the micropyle (mi), embryo (emb) composed of tiny cells, and the thick cuticle (cu) covering the bulging cells of the fruitlet epidermis. Specimen, Catefica 50-S174907 (a–c). Scale bars = 300 Μm (a–c). in The Early Cretaceous Mesofossil Flora Of Catefica, Portugal: Angiosperms
