Received 25 April 1997; revised 23 September 1997

An updated compilation of marine algae for , Mozambique is provided. The list comprises 205 species and infraspecific taxa (64 Chlorophyta, 23 Phaeophyta and 118 Rhodophyta). Nineteen of the seaweeds (9% of all records) have recently been placed into synonymy. The most common orders are Cladophorales (including

Siphonocladales), Caulerpales, Gigartinales and Rhodymeniales. A R+c/p ratio of7.91 ind icates strongly the presence of a tropical seaweed flora.

Keywords: Inhaca Island, Mozambique, sub-tropical seaweed flo ra , Indian Ocean, southern Africa.
