Phycologia britannica, or, A History of British sea-weeds, containing coloured figures, generic and specific characters, synonymes, and descriptions of all the species of algae inhabiting the shores of the British Islands . ew persons who have once seen this species will mistake it foranything else. The only puzzling variety which I have met withis what I have called var. /3. distorta, and this is only puzzling ifseen for the first time in the study. In the field it still retains somuch of the appearance of stunted forms of the species, that itsdifference of general habit does not deceive a practised eye; andits habitat is quite sufficient to account for the distorted forms itassumes. It is found, in the locality indicated, forming scab-like patches on the naked surface of the peat, just within thelimit of the tide, in company with Codium amphibium and Cate-nella opuntia. A habitat more unlike that usually occupied by can scarcely be imagined. The species is thereforestruggling hard against circumstances, on the confines of itscapability of growing. Pig. 1.
