Taxonomic Notes on Marine Algae from Malaysia. VII. Five Species of Rhodophyceae, with the Description of Lomentaria gracillima sp. nov.
The presence of three species of Halymenia (Halymeniaceae), H. durvillei Bory de Saint-Vincent, H. dilatata Zanardini and H. maculata J. Agardh in Malaysia is confirmed by their gross morphology and anatomical features. The reproductive details of H. durvillei including the Halymenia-type auxiliary-cell ampullae are described for the first time. Peyssonnelia inamoena Pilger (Peyssonneliaceae) is reported from Malaysia for the first time, and its monoecious gametophytes and its P. harveyana-type spermatangial development are confirmed. A small-statured new species of Lomentaria (Lomentariaceae), L. gracillima Masuda et Kogame, is described on the basis of such characteristic features as very short and slender axes (up to 8 mm long by 200–250 ?m wide) and the production of tetrasporangial sori in fairly wide regions of ascending axes and erect branches: the subapical or middle portions of the axes; and the proximal to middle portions of the branches.
