Platyloma — Broad -edge. 



Falcata — Sickle-shaped. 



Another handsome Platyloma, easily cultivated if the thrips 

 can be kept from it; they appear very fond of this Fern, and 

 soon make great ravages with its fronds, weakening the plant 

 to a very great extent. 



An evergreen greenhouse species. Native of New Holland. 



Introduced into the Royal Gardens, Kew, in the year 1823, 

 by Mr. Allan Cunningham. 



The form of the frond is lanceolate, pinnate; the pinnae being 

 glabrous, linear-lanceolate, oblong, bluntly-acuminate, falcate, 

 cordate at the base, coriaceous. Rachis and stipes squamiferous. 

 Lateral, adherent to a creeping rhizoma. 



Sori linear, continuous, extending from the base to nearly 

 the apex of the frond, very broad. Indusium very narrow. 



Length of frond from one to two feet, rather erect. 



Colour of the frond above dull green, beneath paler. 



For plants of this species I am indebted to Mr. Pass, gardener
