In the vicinity of the laboratory (on Fivers Island) a fairly large flora occurs along 

 the shores, especially around this island and along the town front, 43 species and varieties 

 having been found growing here, as follows : 



Chroococcus turgidus? 

 Hydrocoleum lyngbyaceum. 

 Lyngbya confervoides. 

 Lyngbya lutea. 

 Enteromorpha linza. 

 Enteromorpha prolif era.

 Ulva lactuca var. rigida. 

 Chaetomorpha linum. 

 Bryopsis plumosa. 

 Codium decorticatum.

 Ectocarpus siliculosus. 

 Ectocarpus mitchellae. 

 Petalonia fascia. 

 Myrionema strangulans. 

 Stilophora rhizodes. 

 Fucus vesiculosus. 

 Sargassum filipendula. 

 Dictyota dichotoma. 



These algae have been found especially north and southwest of Fivers Island, on the 

 laboratory jetties and along the town front, apparently because these localities had more 

 places suitable for attachment. 



Records for other localities in this region have been obtained only for the summer. 

 During this season algae are scarce in the harbor beyond the vicinity of the laboratory. 

 Along the shores of the marshes north of Fivers Island and north of Morehead City there 

 have been found only four species, as follows: 



Padina vickersiae. 

 Erythrotrichia carnea. 

 Porphyra leucosticta. 

 Acrochastium hoytii. 

 Acrochaetium virgatulum. 

 Acrochaetium corymbiferum. 

 Gelidium coerulescens. 

 Gymnogongrus griffithsiae. 

 Agardhiella tenera. 

 Gracilaria confervoides. 

 Gracilaria multipartite. 

 Hypnea musciformis. 

 Champia parvula. 

 Lomentaria uncinata. 

 Grinnellia americana. 

 Chondria dasyphylla. 

 Chondria tenuissima. 

 Dasya pedicellata. 

 Polysiphonia nigrescens. 

 Ceramium strictum. 

 Dermatolithon pustulatum. 



Ulva lactuca var. latissima. 

 Fucus vesiculosus. 



Gracilaria confervoides. 

 Hypnea musciformis. 



No algae were found in the water extending into the marshes. This water is very 

 muddy, is scarcely affected by ordinary tides, and frequently is very hot. 



Found growing only on buoys.
