Cannabaceae, moraceae and urticaceae [PDF]

Review of Palaeobotany and Palynology, 1984
Although this is not the procedure followed in most of the contributions to the Northwest European Pollen Flora, this part combines three families. The reason for this is the close resemblance of the pollen grains in these three families that often makes identification of the pollen a problem.
