Cuticles of Paripteris Gothan, 1941 (Pteridospermopsida) from the Westphalian of Poland
Original language description
Leaf cuticles of two Carboniferous trigonocarpalean ?medullosan? pteridosperms of the genus Paripteris are described. P. gigantea and P. linguaefolia have strikingly similar cuticles. The adaxial cuticles have elongated tetragonal cells. The cells of theabaxial cuticle are polygonal. The haplocheilic stomata are deeply sunken in the case of P. linguaefolia as revealed under SEM. Putative proximal papillae seen light-microscopically appear to be structures encased by sunken stomata. The differences between P. gigantea and P. linguaefolia are restricted to the presence of trichomes respectively trichome bases and differences in stomatal density values.
