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 . n all parts of the stem, arecharacters by which it may most easily be known. To avoidmistakes, I have drawn the magnified portions (fig. 2 and 3)from part of one of the original specimens published in the AlgaeDanmonienses. It sometimes grows to a much larger size thanis represented at fig. 1. I am not aware that this species has yet been noticed beyondthe range of Britain; but the various forms of this puzzlinggenus are so imperfectly deciphered, that it is quite possiblethat it may be found under some other name, among the longlists of species published by various Continental authors. Butthis is a point which can scarcely be settled without a carefulcomparison of authentic specimens in various states. Meanwhile,I trust the figure and description now given will serve to makethe characters of our C. glaucescem more generally known tobotanists out of England. Fig. 1. Cladophora glaucescens :—of the natural Hamuli;—more or less highly magnified. Part of a branch. Plate Ser. :. Fam. Confema. Plate FALCATA, Haw. Gen. Char. Filaments green, jointed, uniform, branched, Fruit, aggre-gated granules or zoospores, contained in the joints, having, at someperiod, a proper ciliary motion. Cladophora (Kiilz.),—from /cXaSos-,a branch, and 4>opea>, to bear. Cladophora falcata; densely tufted, dark-green ; filaments intricate atthe base, ultra-capillary, rigid, much curved, irregularly branched;branches zig-zag, repeatedly divided, the lesser divisions arched, orstrongly incurved and falcate, furnished along their inner faces withshort, secund, blunt ramuli; articulations three or four times longerthan broad, with a dense endochroine, and pellucid falcata, Bare, in Herb.—
