A new species of brachyphyllum from the english uk wealden and its probable female cone


, : A new species of brachyphyllum from the english uk wealden and its probable female cone. Review of Palaeobotany & Palynology 51(1-3): 169-188

A previously undescribed conifer from the English Wealden is formally diagnosed as Brachyphyllum castatum sp. nov., based mainly on large numbers of dispersed leaf cuticles. It is characterized by a highly variable though easily recognisable stomatal apparatus. Conites berryi Seward, which is rediagnosed and described here, is the probable female cone of B. castatum. Neither shoot nor cone can be assigned to a family. A formula devised to allow calculation of parastichy numbers from one side of a compressed shoot is appended.
