The distinction betweenChondrophycus patentirameusandC. paniculatus(Ceramiales, Rhodophyta)
The red algae Chondrophycus patentirameus (Montagne) Nam (‘patentiramea’) and L. paniculata (C. Agardh) J. Agardh were investigated on the basis of type material and recent collections. Both species show the following features: (i) production of two vegetative pericentral cells from each axial segment; (ii) absence of secondary pit connections between cortical cells; (iii) lack of projecting cortical cells near the apex; (iv) absence of lenticular thickenings in the walls of medullary cells; and (v) perpendicular arrangement of tetrasporangia, each of which is produced from the second pericentral cell in each fertile segment with no additional tetrasporangial pericentral cells. However, C. …
Seagrasses along the Sicilian coasts
All seagrass species known from the Mediterranean basin have been recorded along the Sicilian coast, where studies have been carried out at a very local scale and information is fragmented or confined to the grey literature. The objective of this article is to summarise and evaluate current knowledge on seagrass species on the Sicilian coasts, providing an overview of species distribution, genetic diversity, biology and ecology, based on the literature and unpublished data. Most literature studies have been carried out on Posidonia oceanica meadows because of their wide distribution, complexity and ecological importance. In this study, the analyses carried out on P. oceanica structural and …
Typification of the Mediterranean Endemic Deep-Water MacroalgaLaminaria rodrigueziiBornet (Laminariaceae, Phaeophyceae)
Abstract Laminaria rodriguezii Bornet is a deep-water brown alga endemic of the Mediterranean Sea. Lectotypification of Laminaria rodiguezii has been based on both Bornet's protologue and the original material housed at the cryptogamic collections of the Museum National d'Histoire Naturelle de Paris (PC).
