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...
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...
Frankenia is a morphologically complex genus, with some species exhibiting a few diagnostic characters and significant morphological variability. This has led to misidentification or the synonymisation of many names based on one or a few diagnostic traits. This phenomenon affects the annual sea-heath, F. pulverulenta, a Eurasian–Mediterranean herb...

Tamarisk ( Tamarix ) is the predominant but taxonomically complex genus of the Tamaricaceae. The morphologically similar shrub or tree species grow in arid, salt‐influenced habitats of Eurasia and Africa. We sampled woody shoots of seven species at the eastern margin (NW China; T. ramosissima ) and the centre (Uzbekistan; T. hispida ) of the In...
Tamarix is native to Eurasia plus the northern and southern territories of Africa, with some species being introduced into America and Oceania. They are usually found in arid, desertic, or subdesertic areas, often on saline or subsaline soils, in Mediterranean, temperate, or subtropical climates. The genus is renowned for its complex taxonomy, whic...

A taxonomic revision of the genus Tamarix for the Iberian Peninsula and Balearic Islands is provided, updating the Flora iberica account published in 1993. A new dichotomous key for the Iberian and Balearic species is also included. The presence of certain number of species previously cited for the study area (T. arborea, T. canariensis, T. dalmati...
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...

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...
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...

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...
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...
