In the early part of 1962 Dr. R. F. Scagel and the senior author collected at several localities in East Africa (from Malindi, Kenya, southward as far as Mozambique Island, Mozambique) a member of the Fucales which the present authors determined as a species of Cystophyllum (fig. 1). On the basis of material in the herbarium of the University of California and from previous descriptions it seemed that the East African plants could be referred either to C. trinode (Forsskål) J. Agardh, the lectotype of the genus (vide DeToni, 1891, p. 175), or to C. muricatum (C. Agardh) J. Agardh. This uncertainty caused us to make a careful examination of the fairly ample material of these two taxa available to us.² We could find no character whereby an eastern species, Cystophyllum muricatum, which extends westward to the Persian Gulf and Mauritius (Brøgesen, 1939, 1948), can be separated from a Red Sea and East African species, C. trinode.
