Acropora excelsa

Acropora excelsa

Nemenzo, 1971

Corallum ramose; most of branches lie on same plane; lower and upper surfaces easily differentiated. One stem 11.5 cm long, 1.5 cm across at base. Lower surface slightly flattened; branches bear large conical corallites at sides and few widely scattered, small corallites lush with surface; one branch is 5 mm high, 5 mm across at base, 3 mm across just below tip. Upper surface crowded with prominent corallites on apical regions and low distant ones towards the base. Branches proliferous at the apices so that these portions look brush-like.

Axial corallite 3.54 mm across, 2-3 mm exsert, cylindrical, with well rounded apex wall very thick, appearing compact, its outer surface echinulate but not costate. Calice small, 1 mm across. Septa in 2 cycles, thin smooth; primaries hardly reaching radius midpoints, directives slightly distinguishable; secondaries slightly narrower.

Radials of several types. Those at distal regions of branchlets tall, ascending tubulars with thick walls and well rounded apices, 4-7 mm high, around 2.5 mm across; calice slightly oval; secondaries incomplete cycle. Mixed among these tall tubulars are taller, wider-spreading ones with few buds, and shorter adnate tubulars whose lower lips project slightly beyond their oval calices. At the middles of the branches, the dominant radials are adnate tubulars, 4-5 mm long, laid like shingles, some with beak like lower lips; calice round; first cycle of septa complete with directives distinguishable; second cycle incomplete. Also present but fewer are low nariform corallites with thin wall, 1.5 mm across, not more than 2 mm long; their septal complex asymmetrical, even primaries may not be complete, the rest rudimentary. Towards the base of stem and branches, the corallites are dispersed, becoming shorter until they are slightly elevated only or actually flush with surface; calice less than a mm across but primaries wide, complete; secondary cycle represented by 1 or 2 only. Walls of all radials uniformly covered with prominent spines, even in height, very angular in arrangements. Intercalicinal areas narrow, showing obvious pores and similar spines.

Under surface similarly spinulous. Conical large corallites with small calices, some terminal, others lateral in position; primaries prominent but secondaries occasional. Flush corallites have similar septal organization. Pores and slits visible among abundant spines.

Remarks:
The present specimen, C-1329 of only one stem broken off from a wide spreading cluster, according to the collector; presumably it is oblique in position C-1035 is a smaller branch collected from another place; its corallites are narrower with well-rounded tips.
