This is a very handsome and extremely interesting Fern of the 
Malay Archipelago and Islands, for the possession of which, the 
Royal Gardens are indebted to Mr. Wendland, of the Royal 
Hanoverian Gardens. Some may express surprise that a Fern 
with such very elongated linear sori as we have here represented, 
should be referred by Blume to the genus Polypodium (§ Phyma- 
todes) ; but we are so fortunate as to possess specimens exhibit- 
ing all the intermediate grades between the perfect sori of 
Grammitis, § Selliguea, and that form of son which would 
almost justify its being placed in Polypodium. The localities re- 
corded in our herbarium are, a, Java, Zollinger, De Vries, and

bicular sori) ; x. 1, gathered at an elevation of 10,000 feet, upon
