“…The high percentages of endemics, many of them being strictly exclusive to Sardinia and/or Corsica, meet the also relatively high amount of alien plant species of the floras of the two islands: according to the last report made by Podda et al (2012), the alien component for Sardinia reached the amount of 541, of which 58 are invasive, while in the latest study of the Corsican alien flora carried out by Jeanmonod et al (2011Jeanmonod et al ( , 2015 non-native component accounted 443 taxa, of which 31 are invasive or potentially invasive.…”

This article provides a comparison of the vascular alien flora of Sardinia (Italy) and that of Corsica (France), both territories belonging to the Western Mediterranean biogeographic subregion. The study has recorded 598 (90 doubtful) alien taxa in Sardinia (18% of the total flora) while 553 (87 doubtful) in Corsica (17%); six are new report to Sardinia and 27 to Corsica. A total of 234 taxa are common to both islands. Neophytes are 344 taxa (68% of the total) in Sardinia and 399 taxa (73%) in Corsica. The invasive component includes 64 taxa in Sardinia (13% of the alien flora) and 99 taxa (21%) in Corsica, 33 of them common to both territories. The total 740 alien taxa of Sardinia and Corsica are included in 93 families; being Fabaceae the richest. The comparison of the biological spectrum reveals that phanerophytes (202 taxa, 40%) are the most represented in Sardinia and therophytes (149 taxa, 32%) in Corsica. A study of the geographical origin shows supremacy of the American element in Sardinia (170 taxa, 34%) and in Corsica (136 taxa, 29%). The majority of taxa arrived as a result of intentional human introductions, mainly for ornamental use (247 taxa, 49% in Sardinia; 208 taxa, 45% in Corsica). Seminatural, agricultural and synanthropic are the most occupied habitats. These data show the need for joint action to stem the increasingly worrying phenomenon of the alien flora in order to reduce the negative effects on natural habitats and native flora.

Recent distribution of the Euro-Siberian-sub- Mediterranean species Elatine alsinastrum L. (Elatinaceae)

-The general distribution of the endangered Euro-Siberian sub-Mediterranean species Elatine alsinastrum L. is provided using literature, web-sources and herbaria dataset. The distribution pattern shows some regularities: occurrence of locations along river valleys, formation of concentrated site clusters in some lowlands, wide distances between locations or site clusters or single locations between their clusters. The distribution patterns in central Europe seem to be rather well related to the history of the human migration in Europe at least since the Late Holocene. The scattered locations on the eastern part of the distribution area are likely to be a consequence of missing information, rather than to the fragmentation of its distribution.

“…Concerning to life form, many authors settled it as a taxonomic character to differentiate between S. perennis and S. fruticosa. The former is well characterised by rooting branches and a prostrate habit against an erect habit without rooting branches for S. fruticosa (Quézel & Santa, 1963;Pignatti, 1982;Bolòs & Vigo, 1990;Castroviejo, 1990;Coste, 2007;Jeanmonod & Gamisans, 2007;Sánchez-Gómez & Guerra, 2007;Mateo & Crespo, 2009).

“…As a result, pollen morphology should not be considered as a taxonomic character to support the identification among Sarcocornia species. Finally, fruit identification or any other related feature is not usually included in the Sarcocornia treatments (Maire & Quézel, 1962;Quézel & Santa, 1963;Valdés & al., 1987b;Bolòs & Vigo, 1990;Stace, 1991;Coste, 2007;Jeanmonod & Gamisans, 2007;Cabello, 2011), but certain contradictory descriptions have been given about its definition. Meikle (1977) reported the fruit of this genus as an utricule, whereas Castroviejo (1990) indicated it as an achene.…”

The recent description of Sarcocornia hispanica, from SE Iberian Peninsula evidences the notable morphological complexity of this genus. This species is quite close to S. fruticosa, as they both show an erect habit and lack of rooting stems. Besides, S. fruticosa has been traditionally recorded for the same geographical area of S. hispanica. However, the original description of S. hispanica did not include any mention about these two taxa would live together and which ones are the differential morphological characters. Our study aims to clarify their main morphological differences and to address two questions. Firstly, if two close species would be coexisting or secondly, if both species would not live together and then only one erect shrubby species should be recognised for the southeastern peninsular. Therefore, a detailed morphological study of these two species was carried out using vegetative and reproductive characters together with SEM features. Based on the original description, the main morphological features of S. hispanica were compared, plus other features which would support their identification. Our data pointed out the existence of a marked overlapping for most of the studied characters independently of the geographical procedence of the samples. As a result, no significant morphological differences have been found between both taxa, and S. hispanica is proposed as a mere synonym of S. fruticosa. La reciente descripción de Sarcocornia hispanica, para el sureste de la península ibérica, evidencia la notable complejidad morfológica de este género. Esta especie es muy próxima a S. fruticosa, ya que ambas tienen el hábito erecto y carecen de ramas enraizantes. Además, S. fruticosa ha sido tradicionalmente citada para la misma área geográfica de S. hispanica. Sin embargo, en la descripción original de S. hispanica no se indica si ambos taxones conviven y tampoco se aportan los caracteres morfológicos que los diferencian. El presente trabajo se centra en clarificar sus principales diferencias morfológicas, y dar respuesta a dos posibles hipótesis. En primer lugar, si estas dos especies coexisten, o en segundo lugar, ambas especies no convivirían y solo una especie arbustivas de hábito erecto, se reconocerían para el sureste peninsular. Para ello, se ha realizado un estudio morfológico detallado de ambas especies basado en diferentes caracteres vegetativos y reproductivos, junto con características obtenidas con MEB. Se han comparado los principales caracteres morfológicos indicados en la descripción original de S. hispanica, así como otros caracteres que apoyen la identificación de ambos taxones. Los datos obtenidos indican que la mayor parte de las características analizadas están solapadas entre ambas especies con independencia de su procedencia geográfica. Por tanto, no se han encontrado diferencias morfológicas entre ambos taxones, y se propone a S. hispanica como un sinónimo de S. fruticosa.
