The occurrence of this characteristic but not common West Indian spe- 
cies at the Galapagos is interesting. The few specimens collected have 
an abundance of cystocarps whose structure together with the peculiar 
axial structure of the fronds leaves no doubt as to the genus, nor am I 
able, even in their habit, to recognize any specific distinction between 
West Indian and Pacific specimens.

1 the specimens from Elizabeth Bay and some of those from 
Iguana Cove have the typical habit of this species. Some of the 
specimens from the latter locality are more branched than the type but 
appear to belong to the same species.
