Order Caulerpales

Family Caulerpaceae

Caulerpa brachypus Harvey 1860: 333

Plants light to medium green, up to 20 mm tall. Stolons thin (0.5 mm in dried material) bearing short stipes with one or two (dichotomously branched) thin fronds, each 10-15 (-20) mm long and 3-4 mm wide, ovate to strap-shaped, with rounded apices.

Collections, ecology and regional distribution

Uncommon on the south coast: collected from intertidal shores in Transkei, at 23 m off Stilbaai and a few metres deep at De Hoop, but probably more common northwards into Kwazulu-Natal (24-58), where it is found from the intertidal down to 40 m (Coppejans et al. 2005), as C. brachypus forma parvifolia).

World distribution: Widespread in the Indian and Pacific Ocean tropics.

Type locality: Tanegasima, Japan (Harvey 1860).

Note: Coppejans et al. (2005) distinguish forma parvifolia from the considerably longer forma brachypus (Coppejans et al. 2004). See Wynne et al. (2009) for comparisons with similar species of Caulerpa.
