GELIDIACEAE 
Gelidium attenuatum (?).—Name used by REED; not listed by

The species of Gelidium are all called limu loloa, sometimes _ 
limu ekaha-kaha, by the natives, and are extensively used for food. 
They grow on exposed black lava rocks, near the tide line, in 
rough water, where they are constantly washed by the surf. They 
have tenacious holdfasts, and require a knife or chisel for collecting. 
These algae are abundant along the rocky shores of Kauai, Oahu, 
and Molokai, and also occur in considerable quantities on the 
other islands. They produce a dark, viscid gelatine, strongly 
flavored, but suitable for glue manufacture. ReeED states that “our 
species of Gelidium are undoubtedly as gelatinous as the Japanese 
species, but they are not nearly so plentiful.” 
Wrangelia penicillata Agh.—This beautiful, delicate, olive 
green, fernlike species inhabits tidal pools along the reefs and rocky 
shores; cosmopolitan. 
Pterocladia capillacea (Gmel.) Bornet—Uncommon; used by 
the natives of Kauai and Maui, and known by them as /imu loloa; 
occurs also in Mediterranean and Atlantic.
