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 . mixed with the long cells. All con-tain a granular endochrome, the grains of very unequal size. Having a half plate to spare, I take the opportunity of figuringa Rhizoclonium, sent to me some months ago by Dr. Caspary,and found by him near Penzance and Falmouth. It has moreslender filaments than the ordinary R. riparium, and occasionallyappears with longer joints. But the joints vary extremely indifferent threads, and even in the same thread, so that I find itdifficult to fix any satisfactory character by which it can beknown from R. riparium, in the absence of ascertained specimensof that plant. The root-like branches are sometimes much moredeveloped than is shown in the figure, which was made from lessmature specimens than I afterwards received. B. Fig. 1.
