Oss.—The genus is represented in New Zealand and 
Tasmania, by C. grammitidis, which has ovate sori, and may 
be viewed as a multifid-fronded species of Grammitis. As 
regards C. 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. e
