not have the unusually long lower cells so 
characteristic of C. pellucida. It can be separated 
from C. prolifera by the fact that all branches 
of C. prolifera seem to be erect, showing no 
tendency toward the widely divergent to re- 
trorse branching in the lower part of the frond 
of C. doty ana. C. radio sa (Suhr) Kutzing, C. 
wrightiana Harvey, and C. valonioides Sonder 
are three additional species having wide diam- 
eter filaments, but none of these bears resem- 
blance to C. dotyana. 
It is of interest to note that in the Herbarium 
of the University of California there are three 
collections of this proposed species which were 
made in Hawaii. All three collections were made 
in the early part of the century by Miss Minnie 
Reed and are filed under the name of Cladoph- 
ora valonioides Sonder. These specimens bear 
Miss Reed’s numbers 149, 386, and 1160, and 
the collections were made on Maui, Kauai, and 
Oahu, respectively.
