ORDER VALONIACE^l The algae of this order are found only in tropical or subtropicalwaters. Their holdfasts resemble fibrous roots and penetrate thesand or coral on which they grow. GENUS Chamcedoris C. annnlata. When young this alga consists of an annulated tubeformed of a single cell. The annular constrictions occur at short inter-vals, giving it the appearance of being jointed. It grows to the heightof two to three inches, when it ceases to lengthen and produces a densemass of filaments, forming a head or spherical tuft one inch or more indiameter. It is bright grass-green in color, rather rigid and tough, andwhen mature is thinly coated with carbonate of lime. The holdfast is atuft of fibers. The species is found at Key West and is a native of theWest
