Festuca valesiacaSchleich. ex Gaudin newly discovered in the Central Apennines (Italy): a further example of steppe relict in the Abruzzo “dry valley…

2019

Festuca valesiaca Schleich. ex Gaudin subsp. valesiaca is acknowledged as one of the most characteristic grasses of the continental grasslands and steppes of Eurasia. In Italy, the species was known almost only from the continental valleys of the Alpine chain (with the exception of two small populations at the northernmost edge of the Apennines). Here, we report on the first confirmed finding of F. valesiaca subsp. valesiaca in the surroundings of the Fucino Basin, Central Apennines. This finding expands by c. 400 km southwards the species’ range in Italy. The identity of the species was first ascertained by means of leaf cross-sections and stomata measurements, and then confirmed by chromo…

The vascular flora of Nature Reserve “Pizzo Cane, Pizzo Trigna and Grotta Mazzamuto” (NW Sicily)

2009

A floristic investigation was carried out in “Pizzo Cane, Pizzo Trigna and Grotta Mazzamuto” Nature Reserve, one of the largest in Sicily. In spite of the considerable botanical interest of this area, few data were available from classic and recent literature. Based on field investigations, coupled with bibliographic and herbarium researches, we have listed 951 infrageneric taxa belonging to 103 families and 446 genera. A lot of these entities are reported in this area for the first time, for others ancient records are confirmed. Life form analysis shows the dominance of therophytes (44,79%) and hemicryptophytes (27,77%). From a chorological point of view, Mediterranean elements show a grea…

An inventory of the names of native, non-endemic vascular plants described from Italy, their loci classici and types

2019

The census of the loci classici of 1,227 native, non-endemic vascular plants described from Italy is here presented and described. The effective place of publication of accepted names, basionyms and homotypic synonyms were identified and critically verified. The geographic information on the loci classici was excerpted from the protologues, as well as information on typification for the taxa described before 1 January 1958. The names without a holotype are 1,165. For 591 names a lecto- or neo-typification is available in literature, while 572 currently accepted taxa still need a type designation. For ten of these names showing previous ineffective typification, nomenclatural types are desig…

An inventory of the names of vascular plants endemic to C Mediterranean and described from Tunisia

2019

The census of the loci classici of the 98 vascular plants described from Tunisia, endemic to Tunisia or to Tunisia and the surrounding countries, is here presented and described. The effective place of publication of accepted names, basionyms, and homotypic synonyms were identified and critically verified. The geographic information on the loci classici was excerpted from the protologues, as well as information on typification for the taxa described before 1 January 1958. The names without holotype are 48. For 7 of them a lectotypification is already available in literature, 5 are lecotypified here, while 32 currently accepted taxa still need type designation. The new names Festuca scholzia…

Phytotoponymy and Synphytotoponymy in Western Granada Province (Andalusia, Spain)

2009

En el marco de la investigación etnobotánica desarrollada en el poniente granadino, se ha realizado un estudio sobre la toponimia de la comarca con atención a los apelativos de origen vegetal (fitotopónimos y sinfitotopónimos). La información —obtenida de la Gerencia Territorial del Catastro de Granada, de la Junta de Andalucía y de nuestro trabajo de campo— se ha incluido en una base de datos con el programa Microsoft Excell®. Un total de 98 especies vegetales se encuentran representadas en la toponimia local, dando nombre a 593 lugares del territorio. Se aportan comentarios sobre el significado ecológico, paleofitogeográfico y etnobotánico de las especies reflejadas en la toponimia.

The Libyan Collections in FI (Herbarium Centrale Italicum and Webb Herbarium) and Studies on the Libyan Flora by R. Pampanini – Part 2

2016

This work is the continuation of Part 1, published in 2015, and comprises the reconstruction of the original collections of new taxa described by R. Pampanini and other botanists and, where possible, typification of the new names and taxonomical updating. The material studied for the most part concerns Libyan specimens held in the FI and FI-W herbaria but in some case also K, LD, MPU, P, PAD, PAL, ULT. Other material, which Pampanini studied in Florence was subsequently conserved in other herbaria. Specimens belonging to 21 families have been examined, from the Najadaceae to Zygophyllaceae. As well as typification, bibliographical data have been provided for those already typified. In this …
