Cetua'ria. Frond cartilaginous or mem- 

 branaceous, ascending or expanded ; lobe 

 laciniate, smooth and naked both sides;

 the margin of the frond, the lower free, be- 

 ing separated from it, the upper one sessile;

Cenomy'ce. Frond crusty or cartilagi- 

 nous, foliaceous, laciniate, sub-imbricate free

 or empty beneath, terminal attached to the 

 peduncles by their peripheries ; seed-bear- I 

 ing lamina forming the receptacle above, I 

 ihickish, colored, similar within, convex, | 

 reflexed, and attached at the periphery, in-
