South African Seaweeds

Order Bryopsidales

Family Bryopsidaceae

Bryopsis caespitosa Suhr ex Kutzing 1849: 490

Plants caespitose, medium to dark green, forming bushy clumps a few cm high. Main axis about 125 µm diameter, narrowing gradually towards apex. Branching distichous, irregular, more distal branches reaching the level of the apex and imparting candelabrum-like outline.

Branches about 50-60 µm diameter.

Collections, ecology and regionals distribution

South African endemic, collected from De Hoop to Durban KZN (24-51), in the lower eulittoral zone.

World distribution: Also recorded from Namibia, Japan, Korea and some Pacific islands (M. Guiry in Guiry & Guiry, 2014).

Type locality: “Kaffernkuste”, South Africa (Silva et al. 1996).

Note: Stegenga et al. (1996) point out that this species may be synonymous with B. africana, although the latter has thicker axes. However, the illustration of B. caespitosa in Kützing (1856) shows distichous branching, whereas branching in B. africana is polystichous.
