 in all fern regions within the tropics and sub-tropical 

 regions of both hemispheres. 



I have already stated that the presence or absence of

 dium from Goniopteris, and that consequent on its fagacious

 herbarium the indusium fall away and thus become Goniop- 

 teris, much depends upon the age of the fronds when 

 gathered or the condition under which they are preserved, 

 for it is known that in the herbaria of different botanists
