Marine, Benthic algae from Southernmost Greenland.
One hundred and twenty-four species of marine algae from South Greenland are dealt with, of which 11 belong in the Cyanophyceae, 28 in the Rhodophyceae, and 1 each in the Chrysophyceae, Dinophyceae, and Xanthophyceae, respectively, 49 in the Phaeophyceae and 33 in the Chlorophyceae. Of the 11 Cyanop...
