Melittio-Quercion frainetto and Melittio-Quercion confertae are two alliances, which were proposed
about simultaneously 40 years ago through two different papers regarding southern Italy and southern
Greece, respectively. The aims of this paper are to establish valid name, nomenclatural type and distribution
range of these two alliances and to verify whether they display a sufficient degree of syntaxonomic
autonomy when compared to the ecologically and geographically neighbouring alliances. A

Aims: Albania is one of the most diverse countries in Europe (over 4560 plant taxa in 28,748 km²), but is still poorly known. We present here the phytosociological analysis of the forest communities of a mountain area in Central Albania. Study area: The Shebenik-Jabllanicë National Park (SJNP; 34,000 ha), located along the bor- der with Macedonia.

The anthropogenic therophitic grasslands dominated by tall Poaceae of Italy were recently included in the alliance Securigero securidacae-Dasypyrion villosi (Chenopodietea). Similar vegetation types from Sicily, Sardinia, Albania, and Greece were hypothesized to pertain to this syntaxon. In this work, we performed multivariate analyses on 493 phytosociological relevés certainly or likely ascribable to the alliance, gathering personal unpublished data and those available from literature.

The weed vegetation of the bean “Fagiolo Cannellino di Atina” (Phaseolus vulgaris L.) and the red pepper “Peperone di Pontecorvo”
(Capsicum annuum L.) PDO (Protected Designation of Origin) crops was surveyed by means of 16 relevés, sampled in four farms of
southern Latium during July 2019. The relevés were subjected to multivariate analysis, which revealed that the two crops are weeded
by vegetation types referable to two different subassociations of Panico-Polygonetum persicariae (Spergulo-Erodion, Eragrostietalia,
