Azolla (Greek, to destroy by drying). Salviniaceae. A small genus of floating aquatics with small, pinnately branched sts. and minute fleshy 2-lobed lvs., producing 2 sorts of spores in globular sporocarps. The plants multiply rapidly by self-division, and will grow readily in water containing a little nutriment. The species are distinguishable only by microscopic examination. In natural conditions, the plants grow so closely together and multiply so rapidly as to cover very completely any quiet water surface. For this reason, they have been found useful in preventing the propagation of mosquitos in Germany and Panama.
