Vegetation features of two vascular plant species presumed extinct and recently rediscovered in the natural habitat of community interest 8320 from Mt. Vesuvius, Italy
No full textThis paper illustrates the results of a survey aimed at deepening knowledge on vegetation in which Festuca lachenalii and Ophioglossum lusitanicum were recently discovery on Mt. Vesuvius (Italy) after about 200 and 150 years from the last observation, respectively. Both species were previously thought to be locally extinct. These noteworthy microphytes are rare and poorly documented species within their global distribution range. They were found within a habitat of community interest (Habitats Directive 92/43/EEC), where they are subject to extensive anthropogenic impact and require urgent actions for their in situ conservation

Alien plant invasions in Astroni crater, a decades-long unmanaged forest in southern Italy
Full text linkAlien plant invasions in Astroni crater, a decades-long unmanaged forest in southern Italy. In this work, we studied the alien vascular flora of the forest of the Astroni crater. The mixed hardwood forest of deciduous species at the crater base have been withdrawn from management for some decades but that have not achieved yet the characteristics of a true old-growth forest. The floristic list based on field investigation and reference data comprises 20 neophytes, representing 5.4% of the whole vascular flora of the Nature Reserve. Data analysis shows that the exotic flora comprises casual (25%), naturalized (50%) and invasive (25%) aliens. The share of invasive species is related both to a low disturbance level and to good conditions of naturalness in the Astroni forest. The invasive aliens are Ailanthus altissima (Mill.) Swingle, Erigeron sumatrensis Retz., Oxalis pes-caprae L., Phytolacca americana L. and Robinia pseudoacacia L. Interfering with native plant communities, these species could alter the delicate environmental balance and affect its evolutionary dynamics
Anthyllis dalmatica (Fabaceae), a New Endemic Species from Croatia
No full textFollowing a morphometric approach, in this paper a new species, Anthyllis dalmatica, is described and illustrated from Croatia (Southeastern Europe). It belongs to the A. vulneraria species complex (Fabaceae), a poorly investigated and critical taxonomic group for Eurasian vascular flora. The new species is a restricted endemic to the montane belt of Mt. Mosor in central Dalmatia, where it grows on limestone rocky slopes. Anthyllis dalmatica is morphologically closely related to the Italian endemic A. apennina, occurring in the central Apennine, from which it differs by a less-wide calyx, a lower ratio between standard limb length and width, a wider standard, and by the color of corolla and calyx at flowering time, which are dark yellow. Based on current knowledge, we propose that A. dalmatica should be included in the category critically endangered (CR) according to IUCN criteria. To promote its recognition and conservation, a new key to the taxa belonging to the A. vulneraria species complex from Croatia is also proposed
