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. …

Geographical patterns of genetic variation in rosemary (Rosmarinus officinalis) in the Mediterranean basin

Climate changes during the Quaternary had important effects on the evolution of European plant species. The distribution of genetic variability in rosemary, a strictly Mediterranean species of reputed Plio-Quaternary origin for which the diversification centre is hypothesized to be located in the western part of the Mediterranean basin, was investigated across the species range by using plastid microsatellites (plastid simple sequence repeat (cpSSR)) markers. Seven out of the 17 primer pairs screened were polymorphic, with up to four alleles, yielding a total of 17 size variants combined into ten haplotypes. A permutation test to investigate for geographical structure showed no significant …

Lectotypification of the name Cistus stipulatus, basyonim of Helianthemum stipulatum (Cistaceae)

The typification of the name Cistus stipulatus Forsskål (≡ Helianthemum stipulatum (Forsskål) Christensen) is discussed. The designation of the nomenclatural type is based on an assessment of Forsskål’s original material. The name is lectotypified selecting a specimen from the Herbarium Forsskålii in the National Herbarium Copenhagen at C.

The naming and typification of the breadfruit, Artocarpus altilis, and breadnut, A. camansi (Moraceae)

The historical background and typification of the widely distributed and highly appreciated breadfruit tree, Artocarpus altilis (≡ Sitodium altile; Moraceae), and breadnut, A.camansi, is discussed. Sitodium altile is lectotypified selecting a watercolour painting by Sydney Parkinson made in Tahiti in 1769, during James Cook's first voyage around the world (1768–1771) in HMS Endeavour, and preserved at the Natural History Museum of London. A specimen from E. D. Merrill's “illustrative specimens” of Blanco's Philippine plants in the United States National Herbarium is designated as the neotype for A.camansi.

A revision of the typification of some names in the seagrass genera Amphibolis, Cymodocea, Halodule and Syringodium (Cymodoceaceae)

The typification of eight names of species currently included in the family Cymodoceaceae is revised in order to contribute to their nomenclatural stability. The previously designated lectotype of Ruppia antarctica Labill. (≡ Amphibolis antarctica (Labill.) Sond. & Asch.) is cited. Lectotypes are designated here for Zostera nodosa Ucria (≡ Cymodocea nodosa (Ucria) Asch.), Cymodocea rotundata Asch. & Schweinf., Caulinia serrulata R. Br. (≡ Cymodocea serrulata (R. Br.) Asch. & Magnus), Halodule bermudensis Hartog, Diplanthera pinifolia Miki (≡ H. pinifolia (Miki) Hartog) and Cymodocea isoetifolia Asch. (≡ Syringodium isoetifolium (Asch.) Dandy). A neotype is designated here for Z. uninervis F…

Lectotypification of the fountain grass Cenchrus setaceus (Poaceae: Paniceae)

The typification of the name Cenchrus setaceus (Forsskål) Morrone (Poaceae) is discussed, and a lectotype is designated. Cenchrus setaceus is native to northeastern Africa, and cultivated as an ornamental plant in some parts of the world. It is an invasive species in a wide range of natural habitats worldwide, competing strongly with the native flora.

Plastid DNA Homogeneity in Celtis australis L. (Cannabaceae) and Nerium oleander L. (Apocynaceae) throughout the Mediterranean Basin

International audience; Premise of research. Riparian plants are highly dependent on water sources; consequently, general climatic conditions are less important to these taxa relative to woodland and shrubland species. This leads to interesting research questions regarding riparian plant taxa. Research on phylogeography of Mediterranean riparian tree and shrub species is scarce. In this article, we investigated the plastidial genetic diversity in Celtis australis L. (hackberry) and Nerium oleander L. (oleander) throughout the Mediterranean Basin. Both species are distributed in gullies, rivers, and stream banks under warm temperate climates. Methodology. Eighteen cpSSR loci and three noncod…

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).

Typification of Dioscorea communis and its synonym Tamus communis var. subtriloba (Dioscoreaceae)

The typification of Dioscorea communis (≡ Tamus communis, Dioscoreaceae) is discussed. The designation of the nomenclatural type is based on the consultation of Linnaeus’s original material preserved at LINN, the Clifford Herbarium at BM, the Herbarium Joachim Burser at UPS, and the literature cited in the protologue. The name is lectotypified using a herbarium sheet preserved at LINN. A lectotype is also selected for the name Tamus communis var. subtriloba, from a specimen preserved at the Gussone’s herbarium at NAP.

Botryocladia chiajeana and Botryocladia macaronesica sp. nov. (Rhodymeniaceae, Rhodophyta) from the Mediterranean and the eastern Atlantic, with a discussion on the closely related genus Irvinea.

Copyright © 2006 International Phycological Society. Specimens from the eastern Atlantic, Mediterranean and Adriatic seas previously reported as Botryocladia chiajeana showed differences in morphology, and re-examination of Meneghini's original collection of Chrysymenia chiajeana (basionym B. chiajeana) revealed that only the Mediterranean and Adriatic specimens are in agreement with the original protologue, whereas plants reported from the eastern Atlantic are recognised here as Botryocladia macaronesica Afonso-Carrillo, Sobrino, Tittley & Neto sp. nov. The vegetative and reproductive morphology of western Mediterranean plants is examined in detail for the first time, and B. chiajeana is c…
