Abstract

An examination of the material used by Linnaeus in the description of two species of Eschara has shown them to be members of the Galaxauraceae (Rhodophyta). Eschara divaricata Linnaeus is conspecific with Galaxaura cohaerens Kjellman and Eschara fragilis Linnaeus is conspecific with Tricleocarpa oblongata (Ellis & Sol.) Huisman & Borowitzka. Thus the combinations Galaxaura divaricata (L.) Huisman & Townsend and Tricleocarpa fragilis (L.) Huisman & Townsend are proposed. Material from the Plukenet and Sloane herbaria, which has been associated with both E. fragilis and Galaxaura rugosa (Ellis & Sol.) Lamouroux (the type of the generic name), was found to be a mixture of Galaxaura rugosa, Galaxaura obtusata (Ellis & Sol.) Lamouroux, and Tricleocarpa cylindrica (Ellis & Sol.) Huisman & Borowitzka.
