Checklist of the vascular flora of Sicily
2010
ABSTRACT. – Checklist of the vascular flora of Sicily. – On the basis of updated literature data the authors have prepared a checklist of the vascular flora of Sicily. This list subdivided in Pteridophyta, Pinophyta and Magnoliophyta, is arranged in alphabetical order. It includes 3252 specific and infraspecific taxa both native and naturalized. This list reports biologic forms and subforms and the chorotypes. Three name validations and two new combinations are also given. This list is available in electronic format at (http://www.herbmedit.org).
Novedades taxonómicas y nomenclaturales para la flora valenciana, II
2010
Continuando con la actualización taxonómica y nomenclatural de la flora valenciana, se proponen diez combinaciones nuevas y un nombre nuevo para táxones y nototáxones que crecen en el Mediterráneo occidental. Además, se designa un epitipo para Sideritis × angustifolia Lag., híbrido sobre cuya identidad ha existido gran controversia, y un lectotipo para Globularia linifolia Lam. Del mismo modo, se discute la citación correcta del lugar y fecha de publicación de cuatro táxones más.

First finding in Sicily of Bidens subalternans (Asteraceae)
2017
It is reported the presence in Sicily of a new alien species destined to a progressive further spread in the Island. It is Bidens subalternans DC., an annual asteracea of American origin, already known in other Italian regions (Friuli Venezia Giulia, Lombardia, Marche, Lazio and Campania) and in other European countries (Belgium, Corse, Croatia, Cyprus, France, Germany, Great Britain, Montenegro, Republic of Serbia, Slovenia, Spain, Switzerland). The new locality, in Sicily, occurs along the roadside Monreale – Pioppo, south of the city of Palermo. In this station, B. subalternans is found together with B. pilosa subsp. minor and other indigenous and exotic nitrophilous taxa. The population…
Checklist of the vascular plants collected during the 12th “Iter Mediterraneum” in Tunisia, 24 March – 4 April 2014
2015
The vascular plants (plus one alga) collected during Iter Mediterraneum XII of OPTIMA in North Tunisia have been studied. In all, 1374 gatherings were made from 43 localities in the “Cap Bon” region, “Dorsale Tunisienne”, “Tunisie du Nord-Est”, “Vallée de la Medjedah”, “Mogods” and “Kroumirie” areas. They belong to 82 families and 539 species or subspecies. Three taxa are new for the flora of Tunisia (Cerastium diffusum subsp. gussonei, Senecio leucanthemifolius subsp. mauritanicus, and Ulmus minor subsp. canescens), 7 represent new records for the “Kroumirie”, 15 for the “Mogods”, 3 for the “Tunisie du Nord-Est”, 2 for the “Dorsale Tunisienne”, and 8 for “Cap Bon”
On the presence, distribution and conservation status of Lycopodium lagopus (Lycopodiaceae) in Italy
2014
During our work on the Lycopodiaceae account for the upcoming Flora Critica d’Italia (1, 2), we assessed and accepted the presence in Italy of Lycopodium lagopus (Laest. ex Hartm.) Zinserl. ex Kuzen. = L. clavatum subsp. monostachyon (Grev. & Hook.) Selander (2). Already reported by Fiori (3) as L. clavatum f. monostachyum Desv., its presence in Italy was more recently confirmed by Tribsch & Schönswetter (4) and accepted in some subsequent regional works (e.g. 5, 6), but the taxon is not recognized as distinct in the last national checklist of vascular plants (7). Lycopodium lagopus has an arctic-alpine distribution in America and Eurasia (8, 9). Initially described as a variety of L. clava…
A new species of Smyrnium (Apiaceae) related to S. perfoliatum
2015
On the basis of plant collections recently carried out in Sicily as well as the study of the herbarium material kept in PAL and PAL-Gr, a new species of Smyrnium (Apiaceae) is described here. This new taxon, named Smyrnium dimartinoi, is related to S. perfoliatum and is presently known from Sicily, Crete and realistically elsewhere in the Mediterranean. In such range it occurs in open woods and clearings of the Mediterranean-temperate and submontane belt.
Plant trait‐environment relationships in tundra are consistent across spatial scales
2023
Patterns and processes shaping ecosystems vary across spatiotemporal scales. As plant functional traits reflect ecosystem properties, investigating their relationships with environment provides an important tool to understand and predict ecosystem structure and functioning. This is particularly important in the tundra where a changing climate may trigger severe alterations in plant communities as both summer and winter conditions are changing. Here, we investigate the relationships between key environmental drivers including summer temperature, snow persistence, topographic position and soil pH, and species height, specific leaf area (SLA) and seed mass as plant traits. The study is carried…
Algunas citas de interés para la flora valenciana (norte de Alicante)
2008
Se presentan algunos resultados de una catalogación florística realizada en la Estación Biológica de Torretes-Font Roja, situada en las inmediaciones del Parque Natural del Carrascar de la Font Roja (Ibi-Alcoy, Alicante). De los más de 200 táxones catalogados destacamos por su rareza en la Comunidad Valenciana: Linaria repens (L.) Mill. subsp. blanca (Pau) Rivas Godoy & Borja, cuya presencia en la provincia de Alicante se limita a unas pocas citas en las próximas Sierras de Castalla y del Maigmó; Gypsophila pilosa Hudson, arqueófito muy raro ligado a los cultivos tradicionales de cereal y a los consiguientes barbechos, cuyas citas recientes son casi nulas, y Prunus acida C. Koch, especie ar…
