Plants reddish-pink, up to 9 cm tall, somewhat membranous, rather triangular in outline. Erect axes slender, compressed, 1 (-2) mm wide, lateral branchlets in alternating series of one simple, entire, narrowly triangular branchlet and one compound branchlet. Tetrasporangial stichidia stellate or tree-shaped, replacing a compound branchlet.

Collections, ecology and regional distribution

Recorded from Port Alfred to northern Kwazulu-Natal (39-58). Found in intertidal pools and the sublittoral zone (to at least 20 m depth in Kwazulu-Natal).

World distribution: Also recorded from Ghana, Mozambique, and many other warm temperate and tropical localities (Guiry & Guiry 2009). Curiously, recorded from Antarctica by Papenfuss (1964).
