Article: Probable angiosperm pollen from British Barremian to Albian strata

Two species of the genus Clavatipollenites Couper are described. One is a redescription of the type species, Clavatipollenites hughesii, from the Upper Barremian part of the Wealden Series. The other, Clavatipollenites rotundus, is a new species from the Middle Albian Lower Gault. Three species of tricolpate angio-spermous grains are described. Only one of these, Tricolpites albiensis, from the Upper Albian, occurs in sufficient quantity to be formally named as a new species. These forms constitute the earliest record of recognizable angiosperm grains from England.
