Text-fig. 4. SEM micrographs of two types of conifers from the Early Cretaceous mesofossil flora of Catefica, Portugal. (a) Leafy twig of Watsoniocladus cf. virginiensis with opposite-decussate leaves showing convex, keeled, abaxial surface and concave, unkeeled, adaxial surface (P0127, sample Catefica 316). (b), (c) Details of the leaf apex showing amphistomatic abaxial and adaxial surfaces (P0127, sample Catefica 316). (d) Detail of stomata surrounded by a raised rim with finger-like outer papillae showing star-shaped stomatal apertures (arrows) (P0127, sample Catefica 316). (e), (f) Leafy twig of Watsoniocladus cf. virginiensis showing hook-shaped leaves in outline (P0129, sample Catefica 317). (g) Detail of the abaxial surface showing stomata arranged in ill-defined rows (P0129, sample Catefica 317). (h) Leafy twig of Pagiophyllum sp. showing convex, keeled, abaxial surface and concave, unkeeled, adaxial surface (P0126, sample Catefica 318). (i) Detail of the abaxial leaf surface showing serrate margin and scattered stomata (P0126, sample Catefica 318). Scale bars = 1 mm (a, e, f, h); 100 μm (b, c, g, i); 50 μm (d). in Some Conifers From The Early Cretaceous (Late Aptian - Early Albian) Of Catefica, Lusitanian Basin, Western Portugal
