Unfortunately I have only seen Zostera marina from the Atlantic coast; from 
California only Phyliospadix scouleri Stell.; and added to that from the former 
Russian provinces the zygotic P. serrulatus Rupr. as well as Z. marina. I cannot 
believe that this is the end of American see-algae. So for example appears it 
remarkable that Zostera nana which is common on the Indian and Asiatic coasts 
would be totally absent from the western hemisphere when Zostera marına 
occurs in both .Could it be growing together with the enigmatic Thalassıa 
testudinum in the environment of the Gulf especially southern Florida? In that 
respect we got the most from the sea shores ofthe Pacific. We really should look 
at the differences between the two Phyllospadix, the still unknown male flowers 
of these plants and above all the propagation of all sea-phanerogames. In your 
situation I would perhaps let Dr. Bolander for whom I send an extra copy, devote 
himself to those other shores. Perhaps some ofthe Coastal Surveys have 
already explored these problems in many places- if not, it would be easy to get 
to them. In hope of your kind furtherance of our science I remain, with greatest 
respect 
Yours affectionate
