Thalli erect, loosely branched, robust, cartilaginous and range from dark greenish brown to deep purple in colour. Main axes cylindrical throughout, 1.5 to 6 mm in diameter when dried.
Lateral ultimate branches arranged secundly to alternately on the axes; they are terete, attenuated to acute or spinose tips varying in length from 1 to 17 mm and 1 to 2 mm in diameter near their bases. Cross-section of a branch shows a medulla composed of small thick-walled cells interspersed among large parenchymatous cells at the centre. Cortical cells very small. Thalli up to 30 cm in height (Ref. 80758).
Principal raw material in producing kappa-carrageenan and widely used in seaweed farming; used by human as food, blanched in boiling water combined with sliced tomatoes and onions, mixed with a sweet sour dressing made of vinegar, salt and sugar; also used in making jelly-type desserts; a source of minerals (Ca, K, Mg, Na, (Pb, Cd); of high commercial interest internationally as source of carrageenan (Ref. 82232); commercially farmed and forms bulk of the dried "Eucheuma" exported abroad (Ref. 80758). Commercially farmed; first discovered on the reef flats of easternmost Sabah and the southwesternmost part of Sulu Archipelago (Ref. 80758).
