Notes on the status and the current spread of Viburnum tinus L. (Viburnaceae) in Sicily (Italy)
2021
The authors carried out a multi-disciplinary research in order to clarify the native status of Viburnum tinus in Sicily and update the knowledge about its current regional distribution. With this purpose, a large amount of scientific papers on forestry, botany and palaeo- and archaeobotany was consulted; more useful data issued from papers focused on local historical gardens, from archives and from herbarium specimens. The available data suggest that most of the extant nuclei may issue from the recent colonization of plants introduced just few centuries ago. Although the status of the stands found in some warm and humid sites in the surroundings of the city of Palermo and on the Sicani Moun…
Monitoraggio e controllo di insetti infestanti le collezioni dell’erbario dell’orto botanico di Palermo
2021
Gli erbari sono strumenti d’importante rilevanza scientifica che conservano esempi di piante rare, endemiche o estinte, e assumono essi stessi notevole interesse come beni culturali per il loro valore storico ed estetico. Gli erbari possono essere soggetti all’attacco di diverse specie d’insetti che danneggiano le piante essiccate (exsiccata) con la loro attività di alimentazione. Il controllo di queste infestazioni è spesso aggravato dalla difficoltà di poter mettere in atto trattamenti insetticidi. In tale contesto è opportuno adoperare adeguati strumenti di monitoraggio e controllo basati su sostanze attrattive feromonali o alimentari per una corretta gestione integrata degli erbari.…
TAXONOMIC, ECOLOGICAL AND CHOROLOGICAL REMARKS ON CLINOPODIUM MINAE (LAMIACEAE), CRITICAL AND RARE PLANT OF THE SICILIAN FLORA
2017
In a previous contribution (1) the finding in the wild of Clinopodium minae (Lojac.) Peruzzi & F.Conti [Bas. Calamintha minae Lojac.], a critical species close to Clinopodium corsicum (Pers.) Govaerts and well distinct from Clinopodium alpinum (L.) Kuntze subsp. nebrodense (A.Kern. & Strobl) Bartolucci & F.Conti was reported. It is a critical taxon, described by Lojacono, author of the most extensive work on the Sicilian flora (2) based on the examination of the collections of the Herbarium of Palermo (PAL!) (3). In the above cited note, the specific characters as well as the taxonomic relationships with other taxa were highlighted. At the same time, the location of a small population of C.…

Nomenclatural notes on the Polycarpon tetraphyllum aggregate (Caryophyllaceae)
2015
Nomenclatural notes on the aggregate Polycarpon tetraphyllum (Caryophyllaceae) are discussed. The names Hagaea alsinifolia, H. polycarpoides, Poycarpon colomense, P. diphyllum, and P. floribundum are typified, respectively, on an iconography by Boccone (lectotype), and specimens preserved in PAL (neotype), JE (lectotype), MA (Herbarium Cavanilles, lectotype), and COI (Herbarium Willkomm, lectotype). For the nomenclatural purposes, the names P. bivonae (nom. nov. pro P. polycarpoides), P. herniarioides (holotype in K), P. peploides (nom. superfl. et nom. illeg. according to the Arts. 52.1 and 52.2 of the ICN), P. polycarpoides subsp. catalaunicum (holotype in BC), and P. rotundifolium (holot…
From common and used to rare and forgotten: Past and present distribution of the archaeophyte Euphorbia lathyris L. (Euphorbiaceae) in southern Italy…
2019
Our study aimed at clarifying the current and previous occurrence, distribution and status (native vs. introduced) of Euphorbia lathyris L., the caper spurge, in S Italy and Sicily: most of the recent Italian floras and checklists, in fact, do not report this species for this area. To do this, a multi-disciplinary research was carried out taking into account not only botanical but also ethnobotanical and dialectological sources and a survey of the main herbaria of central and southern Italy. Our results point out that E. lathyris was much more frequent, well-known and commonly used in the whole southern Italy and in Sicily until 2-3 centuries ago, and that it probably experienced isolated c…

Su un erbario del XVII secolo conservato presso il Museo Regionale di Messina: Stato di conservazione e proposte per il recupero e la salvaguardia
2013
In this article the conservation status of a XVII Century herbarium from Messina is assessed. This herbarium is attributed to Pietro Castelli, the founder of the Botanical garden of Messina or, most probably, to a pupil of him. It consists of a single volume of 214 pages and is housed in the library od the Museum “Maria Accascina” in Messina. The large part of the specimens stay in poor conditions. Hypothesis for recovery and preservation both in short and long term of this precious heritage are given.
