5. Sargassum Sinelairii, nobis; caule basi semiterete apicem 
versus compresso obtusangulo filiformi, foliis lanceolatis 
basi attenuatis tenuibus nervo evanescente, inferioribus 
majoribus inciso-dentatis, superioribus remote dentatis sub- 
integerrimisve, vesiculis paucis breve petiolatis foliiferis, 
receptaculis brevissimis axillaribus foliolo minuto subtensis 
parum diyisis lobis levibus turbinatis apice abrupte 3-4 
cornutis. 
Has. Bay of Islands, Sinclair, Lyall, &c. 
Nearly related to S. incisefolium, from which it differs in 
the semiterete obtusely angled stem, and in the shape of the 
receptacles; and to S. /acerifolium, from which it is also dis- 
tinguished by the stem, and by the much less deeply divided 
leaves. Like both those species, the present is remarkable. 
for having a single very large leaf, sometimes 3-4 inches long, 
at the base of the branches. This leaf is always more in- 
dented than the rest. 
6. Sargassum scabridum, nobis ; caule. angulato muricato,

perioribus angustissimis nervo attingente valido, vesiculis
