The branchlets form a close fastigiate mass, which unite above, so as to make, by their confluence, a cellular envelope with irregularly hexagonal cells. One or more new tufts are formed at the apex, which again ramify, and thus the whole cactus- like frond is generated (Fig. 42). In this state, however, the plant is void of fructification, which does not, indeed, seem to be produced very generally. The fructifying individuals pre-. Fig. 42. Halimeda opuntia, Lamx.

These, then, are the species, about half the total number found on the atoll reef, which would contribute most of the Halimeda sediments (Hillis-Colinvaux, 1977), but it is likely that two or three from this short list produce the bulk of the Enewetak sediments.

The species incrassata (tridens) and monile were new with Elhs, whereas opuntia had been described by Linnaeus in his "Systema Naturae" (1758), using the binomial Corallina opuntia. Others before this had assigned other names to it, generally polynomials. Ellis' examination of Halimeda material included microscopical study of both surface and internal features (Fig. 12) in what seems to. ,^.

RMRR28FP–. Advances in marine biology: volume 17. Coral fisheries. ECOLOGY AND TAXONOMY OF Holimeda 285 (a) Hard substrates. Proceeding seaward onto the reef from the shore, the first Halimeda species to appear, whether it be a member of the Rhipsahs, Opuntia or Halimeda sections, is determined to a large extent by the substrate available. On the Glory Be reef it is rock, and sprawling over it are large, dense patches of opuntia, sometimes just covered by most low tides, with holdfast filaments developing frequently from between segments where the thallus makes contact with the substrate. When the mapp
RMRR28C8–. Advances in marine biology: volume 17. Coral fisheries. ECOLOGY AND TAXONOMY OF Holimeda 303 possessed the same high Halimeda species richness that was encountered in the fast-flowing lagoonward end of the inter-island channel between Lojwa and Alembel. Species of section Opuntia other than opuntia, the taxa copiosa, distorta and to a lesser extent minima, achieved promi- nence on these knolls. The flattish top of Pole pinnacle lies approximately 4 m below the surface of the water at low tide; its base is reached at about — 40 m. Halimeda distorta and macrophysa filled crevices between colon
