This new taxon, named Allium garganicum, is the single representative of this group in the Italian flora, limited to a small population growing on the limestone rocks near the coast. Its relationships with allied taxa, A. stamineum Boiss.

Spach is a nanophanerophyte whose presence in Sicily is limited to the South-East of the island. A study on seed germination behaviour of seeds collected from some populations indicates low viability[.1] of seedlings which could seriously put the long-term survival of these populations at risk.

(D. rupicola subsp. rupicola, D. rupicola subsp. aeolicus, and D. rupicola subsp. lopadusanus) and growing in different geographical areas of Sicily were tested for seed germination at various temperatures. All populations showed high germination rates with an optimum temperature between 15°C and 25°C. Efficient seed germination might contribute significantly to

Morphological and genetic variability of seven populations attributable to six taxonomic entities (Helichrysum archimedeum, H. stoechas subsp. conglobatum, H. stoechas subsp. barrelieri, H. hyblaeum, H. pendulum and H. nebrodense) was examined, in order to highlight their relationships within the Helichrysum sect. Stoechadina. Morphological analysis showed a clear isolation of populations referred to H. pendulum, H. nebrodense and H. stoechas subsp. conglobatum. Whereas, genetic structure profiling, with 21 ISSRs, displayed a strong genetic relationship within H. stoechas and H. archimedeum accessions, where the latter exhibited evident genetic similarity with H. hyblaeum. Analysis of rbcL cpDNA fragment allowed to identify a shared haplotype between H. stoechas and H. rupestre species, while, through the construction of haplotype network based on trnL-F/rpl32 region, the sampled accessions were properly differentiated as confirmed by the cpDNA consensus network. These results confirmed the high affinity of H. archimedeum with other H. stoechas populations and the closer relationship of H. hyblaeum to H. stoechas respect to H. rupestre.

Despite living in considerable isolation, he managed, above all thanks to Sherard, to correspond and exchange with Ray, Commelin, Tournefort, Triumfetti, Volkamer and Böhm. He participated in the intellectual process and debate on the method of classifying plants that he undertook following the comparison and contrast between Linnaeus and Buffon, in formulating the Linnaeus method and in creating the concepts of genera and species. Cupani and other contemporary botanists were not able to establish a system of plant classification. Each of them was so engaged in researching the distinctive characters of individual plants, in avoiding duplications and synonyms, that they could not grasp what they had in common. Linnaeus, giving them notable recognition, placed them in the category of the “Curious”. These pre-Linnaean researchers contributed to the difficult process of overcoming the rigidity of late-Aristotelian classifications, thanks also to the invention of a “scientific network” that enabled the mutual debate and exchange of botanical material (publications, iconography, seeds and exsiccata).

Codonoprasum RCHB., is investigated. The species was previously confused with other taxa of the A. paniculatun group, but on the basis of herbarium and field investigations A. fuscum is a rare chasmophyte, distributed in Romania and Bulgaria. The description, chromosome number (2n= 16), taxonomy, chorology and ecology are provided. The relationships of this species with some related taxa of the A. paniculatum group are also examined.
