Islands. Descr. Filaments attached by a scutate base, three to twelve inches inlength, as thick as bristles, harsh to the touch, but much less rigidthan C. Melagonium, straight, densely tufted, of a beautifid yellow-greencolour, which fades, in the Herbarium, to a greenish-white. Articulationsabout as long as broad, or a little longer, their contents at length separatinginto two portions. Dissepiments slightly contracted. This is one of the many species of Conferva first brought tothe notice of botanists in the excellent monograph of Dillwyn,where a correct figure is given of it. It appears to be generallydiffused throughout the Atlantic, extending even within thetropics. It is always a more tufted plant than C. Melagonium,paler in colour, of scarcely half the diameter, and, though harsh,far less rigid and quite unable to support itself when removedfrom the water. B. Fig. 1.
