flab. West Indies. 
The last species with another from Africa is placed by Diels in 
a genus distinct from the other gold and silver ferns but the pre- 
ceding species is quite intermediate between this and the other 
West Indian species in its venation.

The first species has anastomosing veins while in the others 
_ the veins are free; until the type species of the genus is better 
: known it will be somewhat uncertain whether all the species thus 
- 88gregated together by Fournier should thus remain. They are 
all characterized by a pedate habit.
