Sansevieria Thunb. (1794) and Sanseverinia Petagna (1787) are generally regarded as separate generic names, and the former has been conserved over the latter (see App. III of the Vienna Code). However, it is determined that the two are not separate generic names but that Thunberg's Sansevieria is a misspelling of Petagna's Sanseverinia. Nonetheless, Thunberg's spelling is to be retained as required by Art. 14.8 of the Melbourne Code. However, the authorship of Sansevieria should be re-attributed to Petagna.

Taxonomic and nomenclatural issues in Asperula aristata L. f. and allied taxa are discussed and the identity of the autonymic subspecies of A. aristata established as being the taxon commonly, but erroneously, called A. aristata subsp scabra. The synonymy of other names in the group is also discussed, and eight of them are typified. Asperula exaristata, applicable ambiguously to a southern Italian taxon, is newly identified and synonymised.

In this paper, we studied the relationships of the only surviving Italian population of Ipomoea imperati (Convolvulaceae), a pantropical sandy coastal species, in Sicily and other populations in the Mediterranean region. Herbarium samples which are representative of extinct populations growing in Campania (Italy) were also investigated together with populations from various Atlantic and Mediterranean localities. Chloroplast DNA microsatellites (cp-SSR) and nuclear ribosomal Internal Transcribed Spacer (ITS) sequences were jointly employed, in order to detect relationships among populations. Our aims were several-fold: (1) to clarify if the species is autochthonous in the Mediterranean basin or a post-Columbian introduction; (2) to investigate phylogeographic patterns in the species and (3) to establish the possible role of dispersal in explaining the patterns observed. Chloroplast microsatellite variation indicates that extinct Italian mainland populations of I. imperati from Campania are not closely related to the extant Sicilian one, as they do not share haplotypes. Chloroplast DNA microsatellite variation is largely between populations, and the within populations component accounts for only approximately 10%. CpDNA data is consistent with a single Mediterranean entry point hypothesis or with the notion that some populations display plesiomorphic variability. ITS data is congruent with the possibility that the presence of I. imperati in the Mediterranean is the result of transatlantic dispersal. The population from Sicily and extinct populations from Campania share an ITS type. A Bayesian analysis employing clock calibration data on an expanded ITS dataset with appropriate outgroups indicates that dates of transoceanic distribution are probably earlier than historical times. © 2013 Magnolia Press.

Ageratina adenophora is recorded for the first time in Italy (Campania region). Its naturalization status and ecology are discussed, also providing a morphological comparison with the related taxa (both occurring in Italy) A. ligustrina and Eupatorium cannabinum. Some remarks on potential threats for habitat and native flora are provided as well.
