AZ6LLA (Greek, to destroy by drying). Salviniacea-. 

 A small genus of floating aquatics with small, pinnate 

 stems and minute fleshy 2-lobed lvs.. producing two 

 sorts of spores in globular sporocarps. The species mul- 

 tiply rapidly by self-division, but will grow readily in 

 water containing a little nutriment. The species are 

 distinguishable only by microscropic examination.
