Text-fig. 34. Synchrotron radiation X-ray tomographic microscopy (SRXTM, a–h) images of "Paisia-like follicle"; Catefica locality, Portugal. a–d) Volume rendering of follicles in lateral (a, c) and ventral (b, d) views showing the decurrent stigmatic region that extends from base of the follicle to the apex; note papillate zone forming a probable stigma along the full length of the ventral suture; e) Longitudinal section (volume rendering cut at orthoslice yz0326) near the base of the follicle showing two ovules with a striate-reticulate surface (asterisks); note transverse fibers lining the inner follicle wall and large cells of the mesocarp; f) Transverse section (volume rendering cut at orthoslice xy2475) of follicle showing two rows of ovules borne on placentae on either side of the ventral suture (asterisks); note also the pronounced and densely-spaced papillae around the ventral suture; g) Transverse section (orthoslice xy1988) of follicle showing two ventral vascular bundles and one dorsal bundle (arrows) and ovules/seeds borne on two placentae, one on either side of the ventral suture; note the remains of the small thin-walled cells of the outer epidermis that cover the thicker-walled cells of the mesocarp; h) Transverse section (orthoslice xy2860) of follicle showing two ventral bundles and one dorsal bundle (arrows) and ovules/seeds in two rows on the placentae, one on either side of the ventral suture; note the remains of small epidermal cells and the large rounded cells of the mesocarp with thicker walls. Specimens, Catefica 49-S174916 (a, b), Catefica 49-S174917 (c–f, h), Catefica 50-S171525 (g). Scale bars = 300 Μm (a–d), 100 Μm (e–h). in The Early Cretaceous Mesofossil Flora Of Catefica, Portugal: Angiosperms
