Turbinaria ornata

Thallus erect, coarse, rigid, leathery, drown, dark brown, 10-20(-30) cm high. Main axes terete, 10-20 cm high, 3-4 mm wide. Branching irregular, sparse. Phylloids stalked, large, obpyramidal or turbinate (in side view), 10-20 mm long, 8-15 mm broad at distal end. Distal marginal blade roundedtriangular (from above view) with coarse and sharp teeth at outer margins; concave center commonly encircled (partially or fully) by inner crown of teeth. The phylloids narrowly triangular at side view, with obtuse and smooth ridges, tapering sharply towards stalk. Vesicles large, embedded in central portion of the phylloids. Cryptostomata scattered over phylloid surface. Receptacles racemose, irregularly forked, 5-7 mm long, develop at the basal portion of the phylloid stalk. Attachment by coarse discoid holdfast and branched rhizoidal stolons. Growing on rocks, on dead corals in the lower intertidal to subtidal zones (to 5 m deep), in sheltered and exposed shores.
