Semina 



To the specimens with which we have been favoured by the Honourable the East India Company 

 in 1825, the name Asplenium rigidum of Wallich is attached: and we should have adopted this, had 



■ 



it not been applied by Swartz to a very different species. Again, the name of Aspidium erosum, 

 Wall., which accompanied Dr. Wallich's original specimens in 1820, is given by Linnaeus to a West 

 Indian species. 



It 



intermediate between Asplenium and Diplazium 



the main central nerve of a fascicle of 



nerves, as it appears to 



bearing the involucra of a Diplazium, while the lateral nerves on 



branches have those of Asplemum.
