Abstract

"The spores from the following cone species have been studied: Lepidostrobus goldenbergi Schimper, Lepidostrobus variabilis Lindley and Hutton, Sigillariostrobus goldenbergi Feistmantel, and Selaginellites elongatus Goldenberg, and it has been found that more than one cone species may produce microspores that are morphologically alike. The association of particular megaspore species with Lepidostrobus goldenbergi and Lepidostrobus variabilis is not considered conclusive proof of their having been produced in these cones."
