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 . o distinctmembranes closely applied together. Fructification scattered over the wholefrond, to which it gives colour. Colour, a full, brilliant grass-green, fadingin age. Substance thin, adhering to paper in drying. This is one of the most beautiful of the British Ulvae, as it isalso one of the less common species. Its gracefully shaped, andelegantly curled fronds look peculiarly well as the plant wavesfreely in the water. It has long been known to botanists, having been distinguishedby Linnaeus, and has been found on very distant shores. It in-habits the Southern as well as the Northern Oceans, probablyextending nearly as far as vegetation extends to the south, thoughas yet we have not had it from any locality south of the Bay ofIslands. The frond consists of a double membrane, so that ithas been by some authors associated with the Enteromorphm, towhich group it affords a direct passage. Fig. 1.
