rgo18] MACCAUGHEY—HAWAIIAN ALGAE I4I 
S. densum Dickie.—Known only from leeward Oahu; Honolulu 
Harbor. 
S. incisum Dickie—Known only from leeward Oahu; Honolulu 
Harbor. 
S. echinocarpum J. Agh.—Recorded only from Hawaii and Fiji. 
S. cymosum Agh.—Widely distributed in the Pacific and 
Atlantic oceans. 
The species of Sargassum are all known as limu kala by the 
natives, and are used for food. They are probably the most 
abundant and widely distributed of the larger algae in the Hawaiian 
Islands. They grow in the shallow waters along the reefs, on stones 
and submerged ledges, and on the reefs themselves. In many 
restricted localities, for example, the leeward shores of Oahu, 
Kauai, and Molokai, they are more abundant than any other 
seaweed. The native uses have been described by REED as 
follows: 
Limu kala is sometimes broken into small pieces and soaked in fresh water 
until it turns dark and soft, then stuffed into salmon before it is roasted, or it 
is chopped with fish heads and salt. It is sometimes ripened by putting in water 
with a few mollusks called Jeho, salted slightly, and allowed to stand for several 
days before eating. Limu kala is more often than any other limu eaten on the 
beach, without any preparation other than rinsing off the sand and breaking 
into convenient pieces for eating with raw fish or squid. It is also sometimes 
put into meat gravies or stews just as it is served. 
DICTYOTACEAE 
Stypopodium lobatum Kuetz.—Occurs in many parts of the 
Pacific and Atlantic; collected at Laysan; thallus at first de- 
cumbent, later ascending; flabellate, palmatifid or lobate, con- 
centrically zoned. 
Padina Commersonii Bory.—Frequent in shallow water within 
the lagoons, often on muddy bottom; widely distributed in the 
Pacific and Atlantic oceans. 
P. Pavonia (L.) Gaill—Abundant along the coral reefs, in 
pools and lagoons; often growing where the water is distinctly 
muddy and brackish; gregarious and forming extensive colonies; 
occurs in many parts of the Atlantic and Pacific; called limu 
pepetao.
