Taxonomic investigation on Allium hirtovaginum group (Amaryllidaceae) from East Mediterranean area
Within taxonomic studies on Allium sect. Codonoprasum from Mediterranean flora, populations belonging to A. hirtovaginum Candargy group were examined. Based on field investigation and herbarium surveyes, this group is represented by very critical and not well known taxa, distributed in the East Mediterranean, showing a marked morphological variability. Currently, the species referable to this group in addition to A. hirtovaginum are also A. pilosum Sibth. & Sm., A. aeginiense Brullo, Giusso & Terrasi and A. nerimaniae Koçyiğit & Kaya. Besides, other 13 species are here described as new to science, they are A. pythagoricum, A. pignattii, A. hippocraticum, A. abanticum, A. velutin…
Rilevanza tassonomica dell’anatomia delle strutture vegetative e delle plantule in specie del genere Kali (Amaranthaceae).
Per approfondire il grado di variabilità morfo-anatomica delle strutture vegetative nel genere Kali, è stato avviato uno studio su sei specie legate a condizioni bioclimatiche ed edafiche differenti. In particolare, sono state analizzate e messe a confronto sezioni trasversali di fusto della zona basale, foglie adulte, brattee e plantule, ottenute da campioni vivi coltivati in analoghe condizioni di crescita per minimizzare l’espressione dei caratteri epigenetici.
Arabis madonia (Brassicaceae), specie critica della flora siciliana
Nell’ambito di ricerche biosistematiche condotte sulla flora endemica della Sicilia, viene esaminata sotto il profilo morfologico Arabis madonia C.Presl, una specie ancora poco nota e critica sotto il profilo tassonomico.
Plant adaptation to drought: evidence and morpho-anatomical diversity in Kali species (Amaranthaceae) from inland and coastal sites.
This study was performed on 6 species of Kali from different habitats and bioclimatic conditions in order to determine the structural differences and variability rate between plant populations from maritime and inland areas, particularly morpho-anatomic functional traits of stem and leaf which allow them to survive under specific environmental conditions.
Phylogenetic and biogeographical inferences for Pancratium (Amaryllidaceae), with an emphasis on the Mediterranean species based on plastid sequence data
The phylogenetics and biogeography of Pancratium (Amaryllidaceae) were investigated, with a focus on the Mediterranean and adjacent areas, with the aim of contributing new information towards a better understanding of the evolutionary history of the genus and the taxonomic placement of P. linosae and P. hirtum. To address these questions, we sequenced four plastid DNA markers: the ndhF and rbcL genes, the trnL(UAA)-trnF(GAA) intergenic spacer and the trnL(UAA) intron, analysing them using parsimony, likelihood and Bayesian approaches. The results show that the relationships among the majority of the species are resolved; however, the relationships of one of the major clades of the genus are…
