A taxonomic reassessment of the Centaurea busambarensis complex (Compositae, Cardueae), with description of a new species from the Egadi Islands (W Sicily)
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. aegu…
Names of Italian vascular plants published by Michele Lojacono Pojero
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.
Invasive alien species – potential cheap resources of plant substances for medicinal use
Some alien species demonstrate rather invasive behaviour. They have high tolerance of various habitat conditions and potent propagation ability. They not only over-compete the local vegetation but suppress the seed development of the native plants. In the newly invaded habitats they might not have suitable herbivores to control their populations. The only effective enemy might be Homo sapiens. Humans are known with their destructive power once an object has become significant for industrial utilization. The aim of this study is to review research data and reveal the potential of Ambrosia artemisiifolia L., Erigeron canadensis L., Xanthium strumarium L. and Dittrichia graveolens (L.) W. Greu…
An analysis of botanical studies of vascular plants from Italian wetlands
Wetlands are essential for life on Earth, but at the same time the most threatened environments due to the gradual alterations associated with climate change and human action. The botanical studies on wetland higher plants carried out in Italy from 1950 until today are analysed in this survey. The 1,265 contributions resulting from this study are analysed from a historical, geographical, and content point of view. Most of the scientific contributions were published in the 1980s and 1990s, often by the same research groups and on a local scale. The predominant research theme is the inventory. Most papers are mainly focused on lakes and rivers. The results of this literature survey point to t…
Typification of the Presl’s name Calamintha canescens (Lamiaceae)
Calamintha canescens is a taxon described in the “Flora Sicula” by K. B. Presl (1826), following the visit made to Sicily a few years earlier (March-July 1817). In the protologue Presl does not report any data on the distribution in Sicily of this taxon that will be almost completely forgotten in later floristic works. Only Nyman (1881) and later Šilić (1979) consider it as a variety respectively of Calamintha nepeta (L.) Savi and C. glandulosa (Req.) Benth. Following the review of a group of critical European taxa belonging to the genus Clinopodium L., lately Melnikov (2016) recovers the ancient taxon Calamintha canescens C. Presl and transfers it to the genus Clinopodium L. Also, the auth…
The Centaurea parlatoris complex (Asteraceae): taxonomic checklist and typifications
A taxonomic account of the Centaurea parlatoris complex (Asteraceae), endemic to Sicily, is presented. This complex includes six taxa, three described in the 19th century (C. parlatoris, C. parlatoris var. tomentosa and C. parlatoris var. virescens) and three recently described (C. sicana, C. giardinae and C. heywoodiana). Starting from the designation of the types for the oldest plant names that have not been typified yet, taxonomic considerations are formulated and C. parlatoris var. virescens is elevated to the rank of species. An identification key and a distribution map complete this account.
