butnot very closely, to paper. To the naked eye this plant has very much the aspect ofLyngbya Carmichaelii, with which (as I have already statedunder Plate CCC.) it is properly a congener; but it is readilydistinguished under the microscope, by the much longer cells, and, especially in advanced specimens, by the contraction- ofthe tube at the dissepiments. It bears a far closer resemblanceto C. bangioides, but is a shorter and comparatively stouterplant, and far less lubricous. The contents of the cells alsoare more granular and dense. It was originally discovered by Mr. W. Weston Young, afriend of Dillwyns, to whom that author was indebted for thedrawings from which the plates that illustrate his work on theBritish Conferva were engraved, and to whom he has dedicatedthis pretty little species.
