142 BOTANICAL GAZETTE [FEBRUARY 
Haliseris plagiogramma Mont.—Foliose parts flat, costate, 
dichotomous; grows far out on the outer margins of the reefs, 
where the heavy surf breaks, also in rather deep water. It occurs 
in other tropical and subtropical waters of the Atlantic and Pacific, 
for example, West Indies and Australia. It usually can be gath- 
ered only by diving or swimming. It grows here and there in 
small quantities only, on all the islands. It is a choice delicacy 
among the natives, who call it limu lipoa. It is often pounded 
and mixed with other seaweeds to give them its peculiar, pene- 
trating, spicy flavor and odor. It is frequently served with meats 
or put into the gravy or stews-to give them a peppery flavor, 
of which the Hawaiians are very fond. All Hawaiians like the 
odor and flavor of this alga, especially with raw fish. It is con- 
sidered particularly delicious with raw flying fish, if simply broken 
and salted slightly. 
H. pardalis Harv.—A very rare species, occasionally washed 
ashore after storms; also occurs in Australian waters; fronds 
linear, dichotomous. : 
Dictyota acutiloba J. Agh. and var. distorta J. Agh.—Recorded 
only from the Hawaiian Islands. 
D. sandvicensis (Sond.) Kuetz.—Fairly abundant; also found in 
Australian waters, Red Sea, and Indian Ocean. 
D. spinulosa Harv.—Rare; in various parts of the North Pacific. 
D. dichotoma (Huds.) Lamx.—Common; widely distributed in 
all oceans. 
The species of Dictyota are all called limu alani by the Hawaiians, 
but are seldom used for food, as they possess a bitter flavor. 
ARTHROCLADIACEAE

tangle, blackish, 6-10 cm. high, much branched and interwoven; 
reported only from the Hawaiian Islands. 
C. fastigiata pacifica J. Agh.—Called by the natives limu wa- 
wahi-wa’a or limu kau-pau, and used as food; occurs in various parts 
of the Pacific, and also along the Atlantic shores of South America; 
fronds caespitose with numerous dichotomously branching fastigiate
