Gelidium

Gelidium, a genus of Algae Florideæ (see SEA-WEEDS). G. cartilagineum and the allied Gracilaria lichenoides are said to be utilised in the building of the edible birds' nests, so much prized by the Chinese (see, however, EDIBLE BIRDS' NEST). These and allied species are largely used for food in the East, as yielding wholesome jellies.
