First finding of Linaria vulgaris (Scrophulariaceae)in Sicily
2007
The occurrence of Linaria vulgaris is reported in Sicily. Such species is known in the Italian Peninsula. Populations of this species have been observed respectively on the Nebrodi Mountains (N Sicily) and in proximity to Aidone (C Sicily).
Floristic traits and biogeographic characterization of the Gennargentu massif (Sardinia)
2013
A study on the vascular flora of the Gennargentu Massif (Central-Eastern Sardinia) is presented. According to our results, the flora consists of 948 taxa: 686 species, 249 sub- species, 10 varieties and 3 hybrids, belonging to 97 families and 427 genera. Three taxa are new findings for the flora of Italy and eight for that of Sardinia. Life form analysis revealed, in particular, dominance of 35.65 % hemicryptophytes, 34.6 % therophytes, 12.13 % geophytes and 11.6 % (nano)-phanero- phytes. As concerns chorology, the Mediterranean element is largely prevailing (68.14%), mainly represented by circum- Medit. (29.1 %) and Euro-Medit. (23.07 %). Endemics are 14.87% of the whole flora (141 taxa), …
Oenothera laciniata Hill (Onagraceae) en la Comunidad Valenciana
2012
Se da a conocer la presencia de la especie naturalizada Oenothera laciniata, como novedad para la flora de la Comunidad Valenciana (E de España); a la vez que constituye su segunda indicación reciente para la Península Ibérica. Se trata de una planta alóctona, nativa de la mitad oriental de Norteamérica, que debe ser considerada como potencial invasora de los ecosistemas mediterráneos. Se ofrecen datos morfológicos para facilitar la identificación de la especie y la futura detección de nuevas poblaciones. Además, se aporta una clave de identificación de las especies valencianas del género. Oenothera laciniata is reported for the first time in the Valencian Community (E of Spain), a report t…
Phelipanche lainzii, nueva Orobáncacea para la península Ibérica
2012
[ES] Se describe una nueva especie ibérica perteneciente al género Phelipanche Pomel (Orobanchaceae): Ph. lainzii, sp. nov., hallada en el noreste de la provincia de Albacete, cerca de la provincia de Valencia (E de España). Entre otras características, presenta por lo general tallo mediano a pequeño, inflorescencia densa, corola azul pálido de tubo estrecho, apenas infundibuliforme y no muy ensanchado en la garganta, con lóbulos del labio inferior no deflexos y cáliz con dientes subulados. Su morfología es parecida a Ph. mutelii (F.W. Schultz) Pomel, Ph. camphorosmae Carlón, G. Gómez, M. Laínz, Moreno Mor., Ó. Sánchez & Schneew. y Ph. nana (F.W. de Noë ex Rchb. fil.) Soják, por lo que se a…
A taxonomic revision of the Capparis spinosa group (Capparaceae) from eastern Africa to Oceania
2015
The variability, autecology and distribution of the Capparis spinosa group have been studied in eastern Africa, Madagascar, southern Asia, Australia and Oceania. In these areas the taxonomic treatment of the group, also represented in holoarctic Regions of the Old World, is still critical. The forms widespread in the study area are here referred to four subspecies of C. spinosa . The recognized subspecies mostly show geographical vicariance, except in some contact areas of the Middle East and western Himalaya. Two nomenclatural novelties, i. e. C. spinosa subsp. cordifolia comb. et stat. nov. and C. spinosa subsp. himalayensis stat. nov., are proposed. Among the recognized taxa, C. spinosa …
New data to distribution of ferns in Tajikistan (Middle Asia)
2016
The paper presents new chorological data of eleven fern species (Ophioglossum bucharicum, Azolla filiculoides, Botrychium lunaria, Gymnocarpium robertianum, Cryptogramma stelleri, Polystichum aculeatum, Asplenium trichomanes, Asplenium viride, Asplenium ruta-muraria, Adiantum capillus-veneris and Salvinia natans) in central Pamir Alai Mts in Tajikistan. Except Azolla filiculoides all of them are native to the flora of Tajikistan. The dry and warm climate in lowlands and middle mountains as well as harsh conditions in higher elevation of Pamir are not suitable for Pteridophytes. Thus, many of fern species are rare in Tajikistan, having less than five locations. List of localities of the spec…

Valantia deltoidea (Rubiaceae) sulle Madonie (Sicilia)
2011
Valantia deltoidea, a therophyte endemic to Sicily, so far known only from its locus classicus on the Rocca Busambra (Palermo, Province) has recently been found at the foot of the Serre di Quacella (Madonie, on dolomite rock, about 1300 m altitude. Besides outlines of taxonomical characteristics of such species, the data on the new locality and the updated distribution are provided here.
New records of the genus Orobanche L. (Orobanchaceae) to the Tunisian flora with lectotypification of the name O. rapum-genistae Thuill.
2023
Based on several field surveys and on the study of original material, we have identified three new species of Orobanche L. s.s. (Orobanchaceae) new to the flora of Tunisia. Orobanche alba Willd., O. calendulae Pomel, and O. gracilis Sm. are reported as new for the country, and the occurrence of O. rapum-genistae Thuill. is confirmed. The lectotypification of O. rapum-genistae is here proposed with a specimen housed in Genève (G). The geographical distribution of the four taxa in Tunisia is given, and details of habitats and hosts are provided. Altogether, the genus Orobanche in Tunisia now includes 18 species; a dichotomous key is proposed to facilitate the identification of these taxa.
Floristic, phenological and chorological differences in the annual vegetation of Sardinia.
2007
The therophytic flora of Sardinia has been split into four main groups, basing on the ecologic requirements of species. The following groups have been recognized: flora of dry entisoils, flora of periodically swampy or submerged entisoils, flora of coastal sites, flora of fields, road edges and human settlements. Either, most frequent or exclusive species were ascribed to each group. A species was considered “exclusive” when its relative frequency outside a given group was estimated ≤10%. Differences have been highlighted within the groups, dealing with chorology, growth form, flowering time, colour of flowers, pollination and seed dispersal strategies.
