long caudate apices of the primary divisions, and of the fronds themselves.

 matter. 



The fronds, which are erect, smooth, translucent, and shining, 

 are ovate- lanceolate, acuminate, and tripinnatifid; the primary 

 divisions lanceolate, and, as well as the apices of the fronds, 

 long-caudate; pinnae alternate; segments brief and entire. 



Length of frond from nine to fifteen inches. Stipes slender 

 and broadly winged almost to the base. Colour of frond bright 

 green. 



Involucres supra-axillary, large, orbicular, and free, two-valved
