No full textIamonico, Duilio, Domina, Gianniantonio, Conti, Fabio (2023): On the identity of Rumex uliginosus and the occurrence of R. dentatus in Italy (Polygonaceae). Phytotaxa 619 (1): 105-110, DOI: 10.11646/phytotaxa.619.1.6, URL: http://dx.doi.org/10.11646/phytotaxa.619.1.
Host-driven morphological variability in orobanche crenata (Orobanchaceae)
Full text linkStudies on interactions between Orobanche species and their hosts are mainly focused on resistance, radical interactions, and haustorium development. The influence of the host plant on morphology of the parasite under environmental controlled conditions is not reported in the literature. With the aim of filling this gap, the results of cultivation experiments of Orobanche crenata on Vicia faba, V. sativa, Pisum sativum, Cicer arietinum, and Lathyrus clymenum are presented. The tested population of O. crenata infected all the studied hosts but showed preferences toward Vicia and Pisum and, in particular, toward a foreign V. sativa cv. The higher resistance of the evaluated local cv. could be due to coevolution between host and parasite. There was little variation in times of emergence: about 110 days on V. faba, while around 125 on P. sativum, C. arietinum, and V. sativa. The shape and size of flowers of O. crenata were influenced by its hosts. The more flourishing the host, the more vigorous the parasite with respect to overall size, number of flowers, and density of the inflorescence. However, significant variations were also observed in the shape of the calyx and the colour of the corolla and stigma. These observations suggest that other taxa of Orobanche that grow in the wild, which are considered to be different species, could be morphotypes of the same taxon, although a process of speciation may be in progress
The floristic research in Italian archaeological sites
Full text linkIn Italy occur about 240 archaeological areas or parks and more than 1500 main monumental complexes;
the number of individual monuments would exceed several thousand. The interest on the
flora of archaeological sites in Italy dates back to the XVII Century. The scope of floristic inventories
can be limited to the mere list of the plants growing into the area or this list can be accompanied
by indication of the dangerousness for the monument represented by single species and the indications
for their management. For this review the basic references concerning the flora of archaeological
sites located in Italy were listed and classified by publication date, area, and main historical period
or civilization to which the complex refers.
Overall 96 references have been collected (73 full articles, 10 chapters of book and 13 conference
abstracts) referring to 47 sites. The large part of these contributions was published between 1990 and
1999. The most investigated regions are Lazio and Sicily. The complexes belonging to the Roman
civilization were the most studied. This even if, in many cases, it is not easy to attribute a monument
to a precise historical epoch because different buildings, over time, have been re-adapted and used
by the civilizations that have succeeded each other. From what has been stated above it is evident
that the botanical prospecting in archaeological areas is still very limited, lacking entirely in several
regions. With the exception of the single Flavian Amphitheatre in Rome (the Colosseum), which has
become a case study, there are no studies published on most of the sites and monuments in Italy. This
review can be a stimulus for scholars and managers in order to undertake targeted campaigns of
prospecting of the biological component occurring in these areas and of deepening knowledge on its
management in order to preserve this historical and artistic heritage
Studies on the genus Atriplex (Chenopodiaceae) in Italy. VIII. Names published by Vincenzo Tineo and Michele Lojacono-Pojero
Full text linkThe typification of the Atriplex names published by Vincenzo Tineo and Michele Lojacono-Pojero is discussed. Atriplex ambigua, A. dealbata, A. graeci, A. halimoides, halimoides var. glomerata, A. halimoides var. perglauca, A. polyphylla, and A. ratundifolia are neo- or lectotypified on specimens preserved at FI or PAL and synonymized with A. glauca (= A. dealbata), A. halimus (= A. halimoides = A. halimoides var. glomerata = A. halimoides var. perglauca), A. rosea (= A. ambigua = A. graeci) and A. tornabenei (= A. polyphylla = A. rotundifolia). The Tineo’s A. arenaria, previously considered as replaced synonym of A. tornabenei, is clarified and typified (neotype) on a specimens deposited at FI
An inventory of the names of vascular plants endemic to C Mediterranean and described from Tunisia
No full textThe 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 scholziana Domina & El Mokni and Sixalix lehoueroui Domina & El Mokni are here proposed. For the names Linaria cossonii Bonnet & Barratte, L. doumetii Coss. ex Bonnet & Barratte, L. paradoxa Murb., Anarrhinum brevifolium Coss. & Kralik, and Onopordum espinae Coss. ex Bonnet (second step) lectotypes are designated here
Importazione massale di dati in Wikiplantbase: l'esperienza con Wikiplantbase #Sicilia
No full textIl progetto Wikiplantbase è stato avviato nel 2013 al fine di offrire un sistema dove caricare record floristici georeferenziati, liberamente accessibili via internet. Sino ad allora, infatti, esistevano un gran numero di banche dati online sulla nomenclatura, tassonomia, erbari, specie aliene, vegetazione, numeri cromosomici e sequenze di DNA, ma non vi era facile accesso ai dati floristici a grande dettaglio geografico. I record floristici costituiscono i dati primari sulla biodiversità utili per qualsiasi ricerca di biologia vegetale. Al fine di aumentare i dati sulla Sicilia disponibili in Wikiplantbase, si sono elaborati e standardizzati alcuni dei dati liberamente accessibili dal sito dell’Herbarium Mediterraneum Panormitanum. L’importazione ha permesso di incrementare, con due settimane di lavoro, i record di Wikiplantbase #Sicilia da 5.069 a 18.858
A taxonomic reassessment of the Centaurea busambarensis complex (Compositae, Cardueae), with description of a new species from the Egadi Islands (W Sicily)
No full textThe results of a statistical biometric study of the Centaurea busambarensis complex, which represents the C. cineraria aggregate in Sicily and its offshore islets, are presented. Seventeen populations, representing all seven previously recognized taxa (four species and three additional subspecies) plus a presumed undescribed one were studied. The statistical analysis (PCA and DA) of 26 morphological characters confirmed these eight taxa as distinct, geographically or ecologically vicarious units of equal weight, not supporting their treatment at different ranks. Consequently, they are recognized here as species, resulting in the description (with illustration) of one of them as new (C. aegusae, endemic to Favignana island, Egadi Archipelago, W Sicily) and in a new combination at species rank (C. seguenzae). A key for identifying the eight species of the complex is provided
Analisi preliminare dello stato di conservazione in situ ed ex situ di 28 specie prioritarie di Allium L. in Italia
No full textPartendo da una checklist aggiornata delle Crop Wild Relatives presenti in Italia, si sono così selezionati i taxa a più alta priorità di conservazione del genere Allium L. (pari a 28 taxa endemici e/o inseriti nelle più recenti Liste Rosse). Si è proceduto alla determinazione della loro distribuzione sulla base di database online, fonti di erbario e bibliografiche per le quali si è effettuato il relativo georeferenziamento. Per gli scopi del presente studio, una volta riportati su mappa i punti corrispondenti alle località di rinvenimento dei taxa oggetto d’analisi, si è poi sovrapposto un layer contenente tutte le aree protette presenti sul territorio (Riserve, Parchi, siti Natura2000, ecc.). Per tutti i taxa almeno un punto ricade all’interno di un’area sottoposta a protezione, mentre solo 75 punti su 217 (35%) ricadono all’interno di Parchi Nazionali, Riserve Naturali e altri siti classificati tra la categoria I e IV (IUCN Protected Area Categories System). Si è poi verificato quali specie sono conservate presso banche del germoplasma tramite la consultazione dei database disponibili. La stima dello stato di conservazione ex situ di questi 28 taxa, sebbene parziale e vincolata al ristretto numero di dati disponibili, ha evidenziato che solo 10 delle specie prioritarie sono conservate presso banche del germoplasma
