Erdtmann's recently proposed classification of the Tremadoc dendroid graptolites and, in particular, the splitting of the genus Dictyonema into benthic (Dictyonema) in planktic (Rhabdinopora) forms are discussed. In view of the Jack of significant details concerning structure, especially in the type species, this distinction seems very premature.
