Nieuwe autochtone zeewieren van de Nederlandse kust

Descriptions and illustrations are presented for attached benthic marine algae considered new to the Netherlands, viz. Hincksia fuscata var. uber and Striaria attenuata. The former taxon was extensively described by Kuckuck in 1961 as Giffordia fuscata var. uber. The new combination was necessary because the generic name Giffordia has been superseded by Hincksia.
