Names of Italian vascular plants published by Michele Lojacono Pojero
2014
Michele Lojacono Pojero (1853-1919) is among the most prolific Italian authors of plant names of his era. A list is presented of the names of 581 new Italian (almost invariably Sicilian) vascular plant taxa he published (303 species, 272 varieties, 6 formae), with reference to existing lectotype designations.
Solunto archaeological park in Sicily: life under mosaic tesserae
2018
Biodeterioration is a complex process induced by the growing and metabolic activity of a wide range of macro and microorganisms, becoming a revelling problem also for the mosaic tesserae of “Casa di Leda” in the Greco - Roman site of Solunto in Sicily. In this case-study, a thick biofilm inducing a deep alteration of mortar and consequently the mosaic tesserae detachment has been highlighted during the restoration plan. The biofilm microbial consortium has been investigated by an integrate approach based on Microscopy analysis (O.M., C.L.S.M.), in vitro culture (Nutrien and Saboraud media) and molecular biology investigation (DNA target sequence amplification, sequencing, sequence analysis)…
Sorbus madoniensis (Rosaceae), a new species from Sicily
2012
Abstract Sorbus madoniensis, a new species of Sorbus sect. Aria, is described, so far known only from two neighbouring localities on Mt. Carbonara (Madonie mountains, Sicily). It is related to S. graeca, which also occurs in the Madonie, and indeed shares with S. madoniensis one of its localities.
A new species of Centaurea (Asteraceae) from Calabria(S Italy)
2013
A new species is described here from the Presila in Calabria (S Italy) and named Centaurea calabra. It belongs to Centaurea sect. Phalolepis and is related to the C. deusta group, namely to C. sarfattiana. Taxonomical characteristics, distribution, and ecology of the new Centaurea are also provided.
Centaurea heywoodiana (Asteraceae), a new species from the Nebrodi Mountains (NE-Sicily)
2020
A new endemic species of Centaurea is here described from the Nebrodi Mountains, in Sicily, and named Centaurea heywoodiana. Information on its morphology, distribution, ecology and taxonomic relationship is also provided.
The genus Tamarix (Tamaricaceae) in Apulia (southern Italy)
2018
This survey is part of the floristic exploration activities on the Italian territory related to the identification of spontaneous and cultivated plants of the genus Tamarix L. A list of tamarisks from Apulia (southern Italy) is here reported together with ecological and distributive data. On the whole, 7 species and 1 variety were recorded in the Apulian region. T. arborea var. arborea is the species with the widest distribution in the Apulian territory. The presence of T. canariensis, T. dalmatica and T. gallica, previously indicated for Apulia by other authors, is currently not confirmed.
A new species of Isatis (Brassicaceae) from the Pollino National Park (Basilicata, S Italy)
2015
A new species, Isatis raimondoi (Brassicaceae) is described from Mt Alpi in the Pollino National Park (Basilicata, Southern Italy). Its relationships with the other species of Isatis occurring in Italy are examined.
Seed cryopreservation of Fraxinus angustifolia Vahl
2016
Fraxinus angustifolia is used for afforestation and for production of both valuable timber and manna , a substance with pharmacological applications. The aim of this research was to establish the optimized condition for cryopreservation of F. angustifolia seeds, in order to protect the germplasm of this species. Germination percentage and mean time of germination of non-treated seeds (control) and liquid nitrogen-treated seeds were established in water or in 10 -6 M gibberellic acid (GA 3 ). The seeds could be cryopreserved with 3% of moisture content (MC) and germinated easily in water (70.0 ± 5.0%), while seeds cryopreserved with 6% MC showed a physiological dormancy. This state could be …
Historical remarks, orginal description and last advances on Pleurotus nebrodensis
2013
Giuseppe Inzenga, the scientist who first described Pleurotus nebrodensis, was one of the major mycologists of the second half of the 19th century. This chapter describes the main biographical aspects of the life of Inzenga and its contribution to science with particular reference to mycology. The chapter also includes notes on the social and academic context of the mid-1800s, which led Inzenga to the original description of P. nebrodensis, the analysis of the critical aspects of nomenclature and the logical path that led us to the recent designation of a P. nebrodensis epitype. An updated description of the taxon and the discovery of the loci classici of P. nebrodensis collections is also …
