Carduncellus, Asteraceae, Eryngium, Apiaceae, distribuição, PortugalRecibido el 9 de septiembre de 2014, aceptado para su publicación el 14 de octubre de 2014Carduncellus cuatrecasasii G. López is a hemicryptophyte that inhabits semi-natural habitats like roadside verges, slopes and grasslands, in dry and slightly nitrified sites, in basic soils (Blanca & Suárez Santiago, 2009). It is endemic to the South of Spain, being circumscribed to the Baetic mountains (Jaén region) on the East, and sierras de Olivenza (Badajoz region) on the West (Anthos, 2014). Throughout its range, it is more abundant on the East and presents a more scattered distribution on the West (Devesa, 1995; Anthos, 2014). It is considered an isolated species inside Carduncellus, due to consistent morphological differences from the other European species, and a particular mechanism of fruit dispersion (López González, 1998). Molecular data confirm its isolation inside the genus (Vilatersana et al., 2000). The species has been classified as “Vulnerable” in “Lista Roja de la flora vascular de Andalucía” (Cabezudo et al., 2005) and it is included in the list of threatened species in “Catálogo Regional de Especies Vegetales Amenazadas de Extremadura” (Junta de Extremadura, 2010) as “of Special interest”.E r y n g i u m  a q u i f o l i u m  C a v.  i s  a hemicryptophyte that inhabits perennial grasslands and dry and rocky places, with preference for basic soils (Nieto, 2003; Cueto & Giménez, 2009). It is endemic to the North of Morocco (Rif region) and South of Spain. Its distribution ranges from Sierra de Segura (Jaén region) in the East to Litoral (Huelva region) in the West, being more frequent in the regions of Cádiz and Malaga (Anthos, 2014).We now add Carduncellus cuatrecasasii and Eryngium aquifolium to the Portuguese flora, being the first records of these species to Portugal. Both species were observed in a roadside near Safara (Baixo Alentejo region), in limestone soils, within a landscape dominated by olive groves and annual grasslands. The two species were found in an herbaceous community which includes other important species like Biarum mendax P.C.Boyce, Iris planifolia (Mill.) Fiori & Paol., Phlomis herba-venti L. subsp. herba-venti, Salvia argentea L. and Tragopogon porrifolius L., the latter being a species which was not included in the most recent Portuguese Flora, apparently by mistake.The C. cuatrecasasii population is composed of several individuals (>50) of different ages occupying an extent of approximately 20 meters along the roadside, in clumps. Although we observed a high flower production, fertile seeds were not detected. A low rate of fertility was also observed in the populations of Extremadura (Junta de Extremadura, 2010). This new Notulae flora iberica 299population is relatively close to the westernmost Spanish populations (approximately 50 km) near Jerez de los Caballeros, which occur in similar ecological conditions (Anthos, 2014). Hence, it is likely that other populations are to be found in this region of Portugal.The E. aquifolium population is represented by just a few individuals (<20), mainly adults, occupying no more than two square meters. All plants were flowering at the time of observation. This new locality represents a very disjoint population, as the westernmost Spanish population is approximately 120 km away (near Sanlúncar la Mayor, Sevilla province), and is 200 km from the main area of distribution (western Subbaetic mountains).In this region of Alentejo, roadsides represent an important refuge for species that do not withstand regular disturbance associated with olive grove maintenance, like regular soil mobilization, and more recently the use of herbicides. Moreover, due to the development of Alqueva dam, a new intensive agriculture system is gradually replacing traditional olive groves by intensive olive explorations. Such alterations in land use are severely threatening the highly diverse plant communities associated with traditional olive groves in limestone soils. These two species are only two examples, among many others, of plants that will certainly suffer (and probably already suffered) the effects of this intensification.Material estudiadoCarduncellus cuatrecasasii G.
