Article
Full-text available
Tamarix minoa is described from material collected on the S Aegean island of Crete (Kriti), Greece. A morphological comparison with the species considered to be closest, T. africana and T. hampeana, is provided. An original illustration showing the main morphological characters of the new species is also given, as are photographs of the new species...
Article
The earlier typifications of 12 names of Tamarix (T. arabica, T. aralensis, T. boveana, T. chinensis, T. hohenackeri, T. karelinii, T. kotschyi, T. leptopetala, T. laxa var. araratica, T. laxa var. subspicata, T. mannifera var. persica and T. pycnocarpa) are discussed. In eight cases, a second-step lectotype was selected, because several specimens...

A report on the genus Tamarix (Tamaricaceae) in Crete is provided. The previously recorded taxa are compared with new collections made on the island and with vouchers found at different herbaria. Three species were fully confirmed: T. nilotica and T. parviflora, collected in the field, and T. smyrnensis, found only in herbarium vouchers. The other...

Tamarix ramosissima Ledeb. is native to Asia, but due to its ornamental use, it is naturalized in many temperate parts of the world, such as Australia, southern Africa, and North and South America. In particular, it has been included among 100 of the “World’s Worst” Invasive Alien Species (http://www.issg.org/database/species/search.asp?st=100ss),...

Five Tamarix taxa were described in Freyn’s posthumous publication (Freyn 1903): Tamarix askabadensis Freyn (1903: 1059), Tamarix karakalensis Freyn (1903: 1060), T. karakalensis var. scoparia Freyn (1903: 1062), T. karakalensis var. verrucifera Freyn (1903: 1062), and T. karakalensis var. myriantha Freyn (1903: 1062). After some historical discuss...

The typification of 20 names in the genus Tamarix is revised. All the names were described from material collected in the Iberian Peninsula and most of them were described by Carlos Pau, Frère Sennen and their collaborators (one name—Tamarix hispanica—was described by Pierre Edmond Boissier). The revision includes the correction of the type status...

The European Red List is a review of the status of European species according to IUCN regional Red Listing guidelines. It identifies those species that are threatened with extinction at the regional level – in order that appropriate conservation action can be taken to improve their status. This publication summarises results for all Europe’s native...

Article
Tamarix is one of the taxonomically most complex genera among the angiosperms, and there is little consensus regarding its infrageneric classification. Here we present the most complete phylogenetic reconstruction of the genus to date. This includes a DNA phylogenetic tree based on nuclear ribosomal ITS, and a plastid DNA phylogeny based on three i...
Article
Fourteen names of North African taxa belonging to Biscutella ser. Biscutella (= ser. Lyratae Malin.), and described by Candolle, Willdenow and Maire, are typified here as a first step towards a taxonomic revision of that series. Lectotypes are designated from syntypes and original material conserved in the herbaria B and MPU: additionally, two epit...

El reglamento de Adaptación Curricular de la Universidad de Alicante (UA) define una estrategia educativa para que el alumnado complete su currículum, con competencias y contenidos académicos suficientes para el correcto ejercicio profesional. Sin embargo, en muchos grados de la UA, las adaptaciones para el alumnado discapacitado se realizan indivi...
Article
Tamarix typically appears in arid and semiarid habitats that are characterised by a broad spectrum of soil salinity. Scarce data are available about the influence of salt on seed germination. The aim of this paper is to analyse the influence of salinity and the loss of viability over time on seed germination of three western Mediterranean autochtho...
Article
In two recent publications (Villar et al. 2014, 2015), we made comments on 24 nomenclatural types in Tamarix Linnaeus (1753: 270). However we overlooked Schiman-Czeika’s (1964) Tamaricaceae treatment for the Flora Iranica, which included mention to all the types of the species recognized by the author. In fact, Schiman-Czeika (1964) always referenc...

This is the sixth of a series of miscellaneous contributions, by various authors, where hitherto unpublished data relevant to both the Med-Checklist and the Euro+Med (or Sisyphus) projects are presented. This instalment deals with the families Amaranthaceae, Asparagaceae (incl. Hyacinthaceae), Callitrichaceae (Plantaginaceae s.l.), Caryophyllaceae,...

More than 15 years after the start, the Euro+Med PlantBase project (E+M), which aimed at providing a comprehensive, dynamic and permanently updated online checklist of all vascular plants for Europe and the Mediterranean countries, is now very close to full coverage. E+M is the most detailed resource on plant biodiversity in the Euro-Mediterranean...
Article
The Helianthemum origanifolium aggregate is widely diversified, with several subspecies distributed in the western Mediterranean basin. Populations from Morocco and Algeria have been usually referred either to H. origanigolium subsp. origanifolium or to H. origanifolium subsp. molle, a taxon usually considered an eastern Iberian endemic. Detailed s...

Remarkable floristic differences in halophilous and hyperhalophilous Tamarix-dominated communities exist along the Mediterrranean basin. These communities have been assigned to Tamaricion boveano-canariensis alliance (Nerio-Tamaricetea class) in the western Mediterranean, whereas the eastern communities have been included in different alliances or...

Xiphion heracleanum was recently described from the Tingitane Peninsula (northern Morocco), on the basis of herbarium material collected mostly in the 19th century. After field work in the Rif area, a new population with three independent subpopulations of X. heracleanum has been discovered in Djebel Bouhachem, over 60 km southeast from Tangiers, t...

A morphological study is presented for taxa of Puccinellia growing in the Valencian Community (eastern Spain). Three species are accepted, and the pres- ence of other taxa usually cited in that territory is clarified or discarded.

Senecio kleinia, an endemic plant of the Canary islands that is commonly used as an ornament in private gardens of the south-eastern Spanish coast, has been discovered invading some native plant communities of the Alicante coastal region. We suggest that a favourable microclimate, and the ability to disperse by both seed and vegetative growth, have...
