Dear Meredith, 
With the exception of several taxonomic problems, I have finished 
the deteminations of your collection of marine algae from Panama 
City, The list is enclosed. 
Two of the taxonomic problems maybe undescribed species, but I 
Jisy® searclMihe liteiature adequately to be ^eaeonahly- 
sure of this. The "unidentified brown (Fam, Striariaceae)" is one 
that has puzzled me for jaars. I collected it first in Alligator 
Harbor in the winter back in 1950 and a number of times since both 
there and in other localities, I have an berbarlum i^ecimen of it 
from the University of Florida which they sent me for deteruination, 
I am fairly certain that it belongs to the Family Striariaceae, but 
I ^all continue to work on it until I come up with something more 
specific than that. 
The unidentified red is another one that is not new to n© , However, 
the only time I collected it, as I recall, was in Panama City Qround 
Tim Smith's dock ever at St, Andrew, I've got to study some heibarium 
material of the genus Hiodophyllis that I have recently obtained 
before I can decided whether or not that is the genus. It certainly 
looks good. 
In addition to these there are several species new to the Gulf of 
Mexico, as one might expect, and extension of ran^s. Tl© Spirogyra 
in 8-2 is a freshwater al^ and I did not attempt to ^t it to species 
as "this is a difficult genus and I have not had much experience with 
it. If you want it identified, I believe Larry Whit ford at N. C, 
State will do it, Let ms know and I'll send it to him, I have some 
Enteromorpha material to identify for him light now, 
I know what you mean when you said you were busy while the summer 
course was in session. I had one inmarii© al^e at Beaufort from 
June 10 until July 20, but I wasn't quite as pu^ed there as you 
were at Alligator Harbor. But it was a fUll-time job anyway. 
The data on the coll^on places ^vith your letter of July 30 will 
enable me to complete labels of the herbariummounts I have made. 
Since I have not made dupl-icate mounts, I will go through tie coll¬ 
ections again and make mounts of as nany of the species listed as I 
can and send them to you when they are ready. I am afraid that you 
will not be able to identify veiy many simply by use of these mounts, 
but of course they will be a help. In a few cases, they are adequate 
in Uiemselves, but only in a few. Even Ihe characteristic Castagnaa 
zosterae could be Taylor's C, howei, as fer as looks are concemed. 
The letter has never been found in hie nor hie m Gulf but there is 
always the possibility. To separate these two, it is necessary to 
compare reproductive structures microscopically. This is just to give 
you an example c£ the limitations of hezbarium mounts as sole Tn<^eTi« 
of identification.
