ULVACEAE 
Monostroma spp.—Several unidentified species occur in brackish 
pools and lagoons along the reefs. 
Ulva rigida Agh.—Occurs along the coral reefs of the larger 
islands and also the atolls. 
U. fasciata Delile-——Thallus stipitate, simple or divided into 
acute segments; fairly common along coral reefs and beaches. 
U. lactuca L. forma genuina Hauck.—This and var. laciniata 
(Wulf.) J. Agh. are common in shallow waters along the coasts and 
reefs. Frequently great quantities are thrown up on the beaches 
by high tides or bykonastorms. U. fasciata is known to the natives 
by the names limu paha-paha or limu pala-haloha. U. lactuca is 
called limu lipa-laha-laha or limu pa-ka-ea. These grow in quiet 
water near the shore and are easily gathered. When air dry these 
species have about 18 per cent water, 14 per cent protein, 50 per 
cent starches, sugars, etc., and 15 per cent ash. They are com- 
monly used as a salad food by the natives, and comprise an impor- 
tant element in the food of the reef inhabiting fishes. 
Enteromorpha flexuosa (Wulf.) Agh.—Very common on stones, 
along the shores and in the harbors; cosmopolitan. 
E. Hopkirkii Agh.—An obscure species. 
E. intestinalis (L.) Link.—Cosmopolitan, with numerous 
varieties and forms; abundant in Hawaiian waters. 
E. Linza (L.) J. Agh—Cosmopolitan, with several forms; 
abundant in Hawaiian waters. 
E. plumosa Kuetz.—Cosmopolitan; not uncommon in Hawaii. 
E. prolifera (Muell.) J. Agh—Cosmopolitan; var. tubulosa 
Kuetz. occurs in brackish pools and ditches. 
E. compressa (L.) Grev.—Cosmopolitan, with numerous va- 
rieties; var. trichodes Kuetz. is recorded from brackish situations. 
All of the Hawaiian species of Enteromorpha grow in shallow 
salt or brackish waters along the coasts, and in brackish pools and 
ditches. They are usually abundant at the mouths of streams, 
especially on the islands of Kauai and Oahu. They are easily 
gathered, and are all considered edible by the natives. These 
algae, known as limu ele-ele, are among the most abundant, most 
popular, and most widely used of the edible algae. They are com-
