The morphology and relationships of Sonderella (Rhodophyta, Rhodomelaceae)

Abstract

Studies on the structure and reproduction of Sonderella linearis, a monotypic genus previously placed in the Sarcomenia group of the Ceramiales, show that it is probably a member of the Rhodomelaceae, allied to the Amansia group. Characters useful in separating the Delesseriaceae and Rhodomelaceae are discussed further in relation to Sonderella.
