2. ''This seems to be the tropical form of P. adianliforme, dis- 

 tinguished by the soft texture from the typical form, but by no 

 other essential eharactei-s, so far as I can see. 11.09." 



The specimens, however, have an indusium with a sinus, which 

 differentiates the plant at once from P. adiantiforme; and the 

 secondary rhachis and the costae are flattened or depressed on the 

 upper side and raised beneath. (See note under P. fragile). 



Mr. Waller's plant differs greatly from P. fragile, and I liave 

 no doubt that, given tlie rhizome and the base of the stipes, it 

 could be described as a new species.
