 aspect a decôinpound forni of Dryopteris dissecta O Ktze (v.A.v.R.^ 

 Suppiem. 1, 165) but the venation is perfectly pleocnemioid. — Higher pinnae 

 adnate and free or connected by a tootli-like intermedial lobe; at least the 

 lowest posterior pinnula pinnatifid or 2-pinnatifid ; costal aréoles narrow, 

 reaching froni the anterior base of the costula to a simple or branched 

 intermedial vein proceeding froni the costa in the direction of the sinus 

 and whether or not continued from the intermedial vein to the posterior 

 side of the next higher costula; other veins forming basai costular areolae 

 and often also a second row of costal ones, otlierwise free, those of the 

 smaller lobes forked, of the larger lobes sparingly pinnate. (Forma dissecta).
