DELCOURT, A. F., DETTMANN, M. E., HUGHES, N. F. 1963. Revision of some Lower Cretaceous microspores from Belgium. Palaeontology, 6, 2, 282–292.
A. F. Delcourt, M. E. Dettmann and N. F. Hughes Most of the new Wealden spore species described in 1955 by Delcourt and Sprumont are refigured; some have been placed in different genera. Two infra-specific taxa in the genus Concavissimisporites have been raised to specific rank. The diagnoses of the genera Biretisporites, Concavissimisporites, and Aequitriradites have been emended.
