Frond palmate, petiolate ; lamina deeply pinnatifid, consisting 

 of several palmately disposed broad linear segments, which, are 

 concrescent at the base of the lamina. The segments, which 

 have a serrate edge, are traversed by a stout median rib, from 

 which numerous parallel veins are given off at a wide angle; 

 the lateral veins are connected by tertiary veins, so disposed as 

 to divide the surface of the lamina into more or less rectangular 

 or polygonal areas, which are occupied by a reticulum of more 

 slender veins.
