" Mr. Lambert is probably the first botanist to whom this very 

 remarkable plant was known. Mr. John Smith considers it af5 

 the type of a new genus, and has described it as such in the 

 Genera Filicum ; but I fear it cannot be separated from that 

 division of the old genus Pterisj now called Allosorus, to which 

 Presl has referred it; and it does seem to connect Cryptogramma 

 Br. with Allosorus, much more so than I had any idea of till I 

 saw this noble species. As in Osmunda the upper part of the 

 frond is converted, as it were, into a panicle of fructification,"

'^ A most superb fern, and much the largest of the genus. 

 Judging from what is known to be the form of the frond in this 

 species, my specimen must have been taken from one which was 

 full three feet long, exclusive of the stipes. It is much divided, 

 but the segments are very compact, and the rich green colour is 

 beautifully varied with the copious, glossy, long, curled, red- 

 brown, chafiy scales and hairs, with which the general and par- 

 tial rhachis and the nerves are clothed." — {Hooker.)
