La flora vascolare del Lazio.

The vascular flora of Lazio (Central Italy) - The long and meticulous data raising on the vascular flora of Lazio region, started by Giuseppe Lusina, then carried on by Bruno Anzalone and finally inherited by Edda Lattanzi and Mauro Iberite, represents a first working phase lasted 60 years and is briefly introduced in this paper. The vascular flora of Lazio region currently consists of 3330 units and 3146 species, divided into 150 families and 896 genera. For each unit the following information is provided: synonym(s), commonness in the regional territory, IUCN threatening status, geographical areas in which it occurs, ideal altitude range and habitat. Since the publication of the latest regional checklist (1996-98), the total amount of units increased from 3185 to 3330 (+4.46%); this is mainly due to the substantial and lively contribution of floristic and taxonomic studies provided both by researchers and by amateurs. Due to the complex geological and environmental patch as well as to the geographical position of Lazio region, this flora is to be considered one of the richest in Italy. Finally, a summarizing outline is given of the priority vascular plants of the region: 1) very rare units, 2) possibly extinct units, 3) threatened units, 4) units uniquely occurring in Lazio region, 5) non-native units; an outline that can serve as an up-to-date scientific tool in managing the floristic heritage of Lazio region

An unknown hotspot of plant diversity in the heart of the Central Apennine: flora and vegetation outline of Mt. Pozzoni-St. Rufo valley (Cittareale, Rieti)

Surprisingly enough, Italy still has some botanically unexplored areas; among these there are some territories between Lazio, Umbria and Abruzzo not included in any protected area. The study area, ranging for 340 ha, includes the mountainous area of Mt. Pozzoni-Mt. Prato-St. Rufo valley, which forms the upper part of the river Velino basin, located in the territory of the municipality of Cittareale (Rieti, Lazio), at an elevation from 1150 to 1903 m a.s.l. The substrate is mainly made of marly limestone of the MesoCenozoic Umbria-Marche sedimentary succession. The climate is Temperate and comprises vegetation belts from the montane to sub-alpine. Land cover is dominated by pastures and deciduous forests, with only a few hay meadows. 794 entities have been detected: 16% are considered rare or very rare for the regional territory with several floristic novelties for the regional flora, 6% of the total was found to be endemic to Italy and only eight taxa were aliens. Four taxa are new for the regional flora of Lazio: Arum cylindraceum, Alopecurus pratensis subsp. pratensis, Hieracium bupleuroides and Trinia glauca subsp. glauca. Forest vegetation is represented by beech forests, while dry grasslands are the most widespread vegetation type. The greatest phytocoenotic diversity was found within the secondary pastures. Particularly interesting is the plant community with Iris marsica, which suggests that limestone mountain ledges can represent a primary habitat for this endemic species of the Central Apennine. The presence of several habitats listed in the EU Habitat Directive indicates how the lack of detailed territorial knowledge can lead to the non-designation of conservation sites in areas of high naturalistic value. These findings showed that botanical explorations in territories which are still not known could contribute significantly to the identification of areas of high interest in conserving plant diversity

Notulae to the Italian native vascular flora: 10

In this contribution, new data concerning the distribution of native vascular flora in Italy are presented. It includes new records, confirmations, exclusions, and status changes to the Italian administrative regions for taxa in the genera Artemisia, Chaetonychia, Cirsium, Cynanchum, Genista, Hieracium, Iberis, Melica, Misopates, Myosotis, Thalictrum, Trifolium, Utricularia, Veronica, and Vicia. Nomenclatural and distribution updates, published elsewhere, and corrigenda are provided as supplementary material

Contribution to the floristic knowledge of eastern Irpinia and Vulture-Melfese area (Campania and Basilicata, southern Italy)

In order to improve the floristic knowledge of the Italian territory, we report the inventory of the taxa collected during the annual field trip of the working group for Floristics, Systematics and Evolution of the Italian Botanical Society held in 2015 in eastern Irpinia and Vulture-Melfese area (South Italy). The investigated territories are located in southern Apennines, along the border between the Campania and Basilicata administrative regions. These areas are scarcely known in terms of vascular flora. The floristic samplings were performed in 19 sites selected as representative of the local environmental diversity as regards to climate, litho-morphology and land-use. The research led to the identification of 4,137 specimens of vascular plants, belonging to 815 species and subspecies, 399 genera, and 85 families. Among these taxa, 42 were endemic to Italy, 38 were included in the IUCN Red List of the Italian Flora, 28 were alien and 5 were cryptogenic in Campania and/ or Basilicata administrative regions. Two taxa, Aquilegia coerulea (casual alien, native to North America) and Lolium ×boucheanum (native), were found to be new for Italy. On the basis of the available floristic literature the first one is also to be considered new for the European flora. At regional scale, we have found 18 taxa new for the Campania and 15 new for the Basilicata region. Finally, 10 taxa were confirmed for Campania. Data obtained during this study, confirmed the important role of a collaborative approach among botanists and the great relevance of these territories for plant diversity

Le piante dedicate a Bruno Anzalone e quelle da lui descritte.

In memory of Bruno Anzalone, we report in this short synthesis the references and the main characters of the two vascular units named after him (Allium anzalonei Brullo, Pavone & Salmeri, Pinguicula vulgaris L. subsp. anzalonei Peruzzi & F. Conti) and of the four ones he described or reassessed [Astragalus aquilanus Anzal., Centaurea scannensis Anzal., Soldano & F. Conti, Sempervivum riccii Iberite & Anzal. e Centaurea aeolica Guss. ex Lojac. subsp. pandataria (Fiori & Bég.) Anzal.]
