The spécimens of the Buitenzorg Herbarium hâve the sori apparently 



acrostichoid, 1. e. tliey are confined to a proportionally stout réceptacle 



placed between the costa and the margin 

 but nearer the former ihan the latter. At full 

 maturity the much contracted fertile pinnae 

 hâve the lamina much recurved, at least in 

 dried material, and the capsules are then so 

 denseley crowded that it seems as if they are 

 entirely covering the pinnae on ail sides.
