The town of Cedar Keys, Florida, is ieee n the west coast 
of the peninsula, a little north of the 29th parallel of latitude and 
nearly one hundred miles north of Tampa. The second week of 
January was spent here with the purpose of obtaining some 
information as to nature of the marine flora at this point in the 
winter season. My previous visits to Florida in quest of marine 
algae had been in the spring and autumn. The water is shallow 
for many miles about Cedar Keys, with many reefs, shoals, 
and small islands and with considerable variety in the nature of 
the sea-bottom. The physical conditions would seem to favor 
an abundant and diversified seaweed flora, but, at the time of m: 
visit, at least, the marine algae did not appear particularly 
numerous, either as to species or individuals. About forty 
species, perhaps, were observed and collected. On three days, 
weeds about the only distinctively tropical or subtropical species 
secured was Caulerpa prolifera. It is probable that more of the 
tropical species might have been found on the reefs and shoals 
where the collection of sponges is carried on, but these sponge 
reefs are said to be fifteen miles or more to the seaward of Cedar 
Keys and 1 was disappointed in my efforts to reach them. It 
may be remarked that a common and conspicuous seaweed of 
the Cedar Keys region in the first half of January appears to be 
Agardhiella tenera, a species that is common in Long Island Sound 
and about New York in summer and autumn, ee very rarely 
met with in the winter. A visit to Cedar Keys at other seasons 
of the year would doubtless lead to finding a greater number o 
marine algae and to securing data of interest as to their seasonal 
occurrence.
