stipites distant a span to a foot and 2 feet long the base 

 copiously crinite (as in the caudex below) the rest and the 

 rachises partially and sparsely setoso-paleaceous, fronds a 

 span to 1 and 2 feet long deltoideo-ovate suddenly acuminate 

 3-4-pinnate more or less coriaceo-membranaceous glossy, 

 primary pinnee all petiolate lanceolate finely acuminate, lowest 

 primary ones with the basal secondary pinnae very much 

 elongated (hence the frond is pedate) and again once or twice 

 pinnated, pinnules obliquely ovato- or rhomboideo-lanceolate 

 pctiolulate subfalcate subauriculate mostly mucronato-serrate, 

 sori generally in two rows on each pinnule, involucres rather 

 small usually plane orbicular and peltate rarely subreniform.
