Marine and coastal plant biology

By means of gradual adaptation of the marine Bangia fuscopurpurea (Dillw.) Lyngb. to an almost freshwater medium and of the freshwater B. atropurpurea (Roth) C. Ag. to sea water, it is concluded that these Bangia taxa are conspeciflc and that the correct name is B. atropurpurea (Roth) C. Ag. This adaptation takes place during the formation of neutral spores, which are capable of 'normal' growth in a medium with a salinity which does not differ too much from that from which they were taken. A definition of 'normal' growth is given.
