 colour. 



Stipes slender and terminal, and as long as the frond. 

 Stipes and rachis smooth. Caudex brief, tufted, and scaly. 



Veins flabellately forked.

 raised from spores by Mr. Sim, of Foot's Cray. It differs in 

 havincr the teeth of the lobes acute, instead of obtuse. I am 

 indebted to Mr. Sim, of Foot's Cray, for fronds.
