Short description Morphology

Thalli large, dark brown or yellowish brown, strongly attached to hard substrates by a well-developed discoid holdfast. Branching subdichotomous-divaricate, forming angles of less than 90°, narrowing at the distal portion of the thallus. Branches strap-shaped, 4 to 8 mm across, with a distinct midrib running throughout the entire length. Parallel to the midrib on both sides are sori of hairs. Margin of the blades entire to slightly undulate. Cross-section of a ranch shows 2 layers of cells; cells of the midrib polyhedral to quadrangular in surface view. Thalli up to 25 cm in height (Ref. 80758).

Biology     Glossary (e.g. epibenthic)

Used as medicine: antitumor (Ref. 80758). Attached to coralline substrate at upper subtidal zones exposed to moderate to strong water movement. Generally limited to rocky, waved-exposed habitats, such as reef crests and slopes. Detached thalli may also be found among drifting seaweeds. Dredged from depths of 33 to 73 m, attached to shells or coral fragments (Ref. 80758).
