A new species of red algae, Plocamium fimbriatum, is described from the Sultanate of Oman. It is distinguished by the following suite of characteristics: robust main axes (to 25 cm in length by 4-6 mm in width) with marginal branches produced in series of alternating pairs; production of abundant marginal proliferations resulting in a densely fringed appearance, and tetrasporangial stichidia arising along axillary margins and in the proliferations. The species joins the growing number of new taxa that have been described recently from the benthic marine algal flora of the northern Arabian Sea, a region impacted by the summertime monsoon of nutrient-rich, relatively cold-water conditions. A census of the 35 other species now recognized as belonging to the genus Plocamium is provided. The combination Plocamium cartilagineum (Linnaeus) P. Dixon var. uncinatum (C. Agardh) M.J. Wynne comb. nov. is effected.
