Invalidation of the Genus Vaughaniella

Abstract

AN examination of specimens of an alga at first assigned to Vaughaniella rupicola Boergs. has led to the conclusion that the genus Vaughaniella Boergs.¹ represents the basal rhizomatous portion of the genus Padina Adans. In southern Queensland, these flattened rhizomes, often showing transition to fan-shaped thalli, are found at the base of plants of Padina commersonii Bory in both estuarine and exposed localities; but around the margins of shallow lower littoral pools, on exposed rock platforms, rhizome development may sometimes take place without any production of fan thalli.
