The results of a statistical biometric study of the Centaurea busambarensis complex, which represents the C. cineraria aggregate in Sicily and its offshore islets, are presented. Seventeen populations, representing all seven previously recognized taxa (four species and three additional subspecies) plus a presumed undescribed one were studied. The statistical analysis (PCA and DA) of 26 morphological characters confirmed these eight taxa as distinct, geographically or ecologically vicarious units of equal weight, not supporting their treatment at different ranks. Consequently, they are recognized here as species, resulting in the description (with illustration) of one of them as new (C. aegusae, endemic to Favignana island, Egadi Archipelago, W Sicily) and in a new combination at species rank (C. seguenzae). A key for identifying the eight species of the complex is provided. © 2017 Informa UK Limited, trading as Taylor & Francis Group

The group of Centaurea (sect. Acrolophus) cineraria (Compositae) in Sicily includes four currently accepted species plus four taxa that have been considered, with some doubt, as subspecies of one of them (C. panormitana). In total, discounting recombinations and replacement names, 11 names (seven specific, three varietal, one of a forma), all based on Sicilian material, were published by past authors for these eight taxa. Two of the names had their holotype indicated upon publication; two have been lectotypified previously; six (C. busambarensis var. obtusiloba, C. cineraria var. soluntina, C. cineraria var. umbrosa, C. todaroi, C. todaroi f. seguenzae and C. ucriae) are lectotypified here; and C. panormitana is neotypified. The whole group is extremely variable and the delimitation of most taxa is still uncertain. Pending further study, including the sampling of wild populations, no taxonomic reassessment is therefore attempted here, with one exception: the merger of C. panormitana subsp. ucriae with C. panormitana subsp. panormitana. © 2016 The Authors.

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.

A new species from Montevergine in Campania, Hieracium barrelieri, is described in detail. It is closest to H. acanthodontoides of . H. murorum var. barrelieri, an obsolete taxon described by Tenore, is also discussed, as it was partly based on the same population. © 2015 Magnolia Press.
