Notes on the distribution, ecology and conservation status of two very rare sedges (Carex, Cyperaceae) rediscovered in Sicily (Italy)
2017
New data on the geographical distribution and ecology of two rare taxa of Carex collected in the area of the Nebrodi Mountains (Sicily) are provided; the Sicilian populations of both taxa are at the border of their respective ranges, and their regional distribution is still poorly known. The new population of Carex x boenninghausiana reported here confirms the presence of this hybrid in Sicily, but at the same time it represents the only known population currently occurring in Italy; in fact, the other - so far only - known Italian population is considered extinct. The second report concerns Carex grioletii, recently considered doubtful for the Sicilian flora, whose new population here repo…
Distribution, ecology and conservation survey on theCeltis tournefortiisubsp.aetnensis(Celtidaceae: Cannabaceae) populations in Sicily
2014
Results of research on the Celtis tournefortii subsp. aetnensis (Celtidaceae-Cannabaceae) populations in Sicily, based on the monitoring of the various nuclei distributed in the territory, are presented. In particular, two new important unpublished stations located in the southern part of the Sicani Mountains, widespread over an area of approximately 75 hectares, are reported. It is highlighted that the species, besides the lava flows of the western slope of Mount Etna (Catania province), is tied to conoids present in five other disjointed sub-ranges, often with fragmentary and relictual stations: (1) Nebrodi Mountains inland (Cesarò territory, Messina province); (2) Madonie Mountains inlan…
