Revision of the Red Algal Genus Galaxaura with Special Reference to the Species Occurring in the Western Indian Ocean

Abstract

A study of Galaxaura (Nemaliales, Chaetangiaceae) from Hast Africa (especially Tanzania, Mozambique, South Africa and Malagasy Republic) and Mauritius has revealed that the following nine taxa are represented: G. diesingiana Zanardini, G. fasciculata Kjellman, G. lapidescens (Ellis et Solander) Lamouroux, G. lenta Kjellman, G. margifiata (Ellis et Solander) Lamouroux, G, oblongata (Ellis et Solander) Lamouroux, G. obtusata (Ellis et Solander) Lamouroux, G. rugosa (Ellis et Solander) Lamouroux and G, subverticillata Kjellman. The species recognized include seven of the 62 treated by Kjeilman in 1900 and two species not treated by him. The nine species encompass 38 species reported by various authors for the region. A key to the species, comments on their morphology, illustrations of their growth habit and structure, and discussions of their taxonomy and nomenclature are presented.
