A beautiful Fern, and, as it appears, by no means uncommon in the East Indies ; yet, strange to 
say, no one appears to have described it from his own observation, except Poiret in the Zncyclo- 
pédie Botanique. Dr. Wallich tells us that it is common on the trunk of almost every Palm 
throughout India, and it was in such a situation that our specimens from near Calcutta were 
gathered by Dr. Scouler. To the Liverpool Botanic Garden it has been sent from China, and 
it is there cultivated successfully in the stove.
