Obs. — The genus is represented in New Zealand and 

 Tasmania, by C. grammitidis, which has ovate sori, and may 

 be viewed as a multifid-ironded species of Grammitis. As 

 regards G. trichomanoides, it is common throughout the 

 tropics of the Western Hemisphere, and the different 

 appearances it assumes have led to some of the forms 

 being described as distinct species. It is also found in 

 Sikkim Himalaya, but it is probable that if we had the 

 opportunity of seeing living plants from the different 

 localities, characters might present themselves to show 

 that they are distinct species. Indeed, all that is known 

 of the species of this genus is derived from herbarium 

 specimens only, no living species having yet been intro- 

 duced into this country.
