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 is reported. It was held in 2013 along the Maddalena Mountains a mountain ridge of the southern Apennines located between the Basilicata and Campania administrative regions (southern Italy) considered as being poorly characterized in terms of vascular flora. A total of 701 units belonging to 74 plant families were recorded including two varieties and four hybrids.Thirty-five taxa resulted endemic to Italy and only 11 alien species were detected while 36 taxa are new or confirmed for the regional floras of Basilicata and/or Campania. In particular 12 taxa are new for Basilicata while four are confirmed. Regarding Campania 14 taxa resulted new for the regional flora and five were confirmed.
New floristic records, regional flora, southern Apennines, vascular flora
In recent years, the working group for Floristics, Systematics and Evolution of the Italian Botanical Society has been very active in increasing the knowledge about the vascular flora of poorly known areas. Specifically, several contributions have been published regarding southern Italy (e.g.
The selection of the areas to be investigated has been mostly addressed to fill the gaps pointed out by
In this paper, we present the results of the field trip held in 2013 in the southern Apennines and organized by the botanists of the University of Basilicata (L. Rosati, S. Fascetti and V.A. Romano), aimed at increasing our floristic knowledge of the western border between the Italian administrative regions of Basilicata and Campania.
The investigated area includes the central part of the Maddalena Mountains and some neighbouring biotopes of particular interest for vascular plants (Suppl. material
The Maddalena Mountains are a carbonatic ridge, aligned from NNW to SSE and extending for 40 km. They are located between the intramountain basins of the Val d’Agri (Basilicata) to the east and the Vallo di Diano (Campania) to the west. The altitude ranges from 300 m a.s.l. at the bottom of Melandro Valley, to 1503 m a.s.l. at the top of Serra Longa.
This sector of the southern Apennines is characterized by a remarkable geological complexity, mainly due to the effects of a translational tectonic that placed the formations of the Mesozoic carbonatic platform on the silico-clastic Lagonegrese Units. The Holocenic detritus represents the connection with the recent alluvial deposits of the main valleys due to tectonic morpho-structures shaped like a “graben” (
The morpho-structure of the Maddalena Mountains is less affected by karst phenomena than other massifs of southern Italy; however, karstification is well developed in those areas where Cretaceous limestones prevail on Triassic dolomites (
Rainfall in the area is concentrated in the autumn-winter period, with a maximum in November-December and a minimum in summer (July-August); a summer drought of two to three months also occurs (Suppl. material
According to the classification proposed by
The Maddalena Mountains are partially included within the Appennino Lucano National Park and within two Natura 2000 sites: “Monti della Maddalena” (code IT8050034) and “Faggeta di Moliterno” (code IT9210110). Nevertheless, this territory has never been the object of specific botanical contributions, except for the biotope “Faggeta di Moliterno” located in the southern part of the ridge (
To maximize vascular flora sampling, 12 sites were selected as representative of the local diversity in terms of climate, litho-morphology, and land use (Suppl. material
The work was coordinated and the floristic list drawn up by the organizers with the contribution of all participants to the excursion. A revision of the samples collected during the field work was carried out at the University of Roma Tre (27–28 February, 2014), followed by specific studies and comparisons of unidentified taxa. Some critical samples were sent to specialists for determination: Viola (A. Scoppola, Viterbo), Orobanche (G. Domina, Palermo), ferns (D. Marchetti, Massa).
Nomenclature and taxa delimitation followed the updated version of the Checklist of Italian Flora (
For each unit at least one herbarium specimen was prepared and preserved in public or private herbaria listed in Suppl. material
The floristic list (Suppl. material
For each unit, we reported locations of collection, using the abbreviations given in Suppl. material
In total, more than 2600 samples of vascular plants were collected, belonging to 701 taxa and 74 families (see the complete floristic list in the Suppl. material
Thirty-five taxa are considered endemic to Italy (
• Achillea rupestris subsp. calcarea (Huter, Porta & Rigo) Greuter
• Alyssum diffusum subsp. calabricum Španiel, Marhold, N.G.Passal. & Lihová
• Epipactis collaris S.Hertel
• Epipactis lucana H.Presser, S.Hertel & V.A.Romano
• Knautia lucana Lacaita & Szabó
• Koeleria lucana Brullo, Giusso & Miniss.
• Koeleria splendens C.Presl
• Lathyrus jordanii (Ten.) Ces., Pass. & Gibelli
• Scorzonera villosa subsp. columnae (Guss.) Nyman
• Viola aethnensis subsp. splendida (W.Becker) Merxm. & Lippert
Only 11 taxa were alien (Agrostemma githago L., Centaurea cyanus, L., Erigeron sumatrensis Retz., Gladiolus italicus Mill., Isatis tinctoria subsp. tinctoria, Malus pumila Mill., Papaver dubium subsp. dubium, Petroselinum crispum (Mill.) Fuss, Prunus dulcis (Mill.) D.A.Webb, Senecio inaequidens DC., Veronica persica Poir.).
Thirty-six taxa have to be considered as floristic novelties because either new or confirmed for the regional flora of Basilicata and/or Campania.
In particular, 12 resulted new for the flora of Basilicata:
• Asparagus tenuifolius Lam.
• Blackstonia acuminata subsp. aestiva (K.Malý) Zeltner
• Carex humilis Leyss.
• Colchicum lusitanum Brot.
• Iberis umbellata L.
• Jasione montana L.
• Koeleria splendens C.Presl
• Lupinus albus subsp. graecus (Boiss. & Spruner) Franco & P.Silva
• Rosa inodora Fr.
• Rosa mollis Sm.
• Valerianella microcarpa Loisel.
• Viola eugeniae subsp. eugeniae
As regards the following units, the subspecific rank for Basilicata was specified:
• Rhinanthus alectorolophus subsp. alectorolophus
• Silene italica subsp. sicula (Ucria) Jeanm.
Four taxa were confirmed for Basilicata:
• Cardamine amporitana Sennen & Pau
• Thalictrum simplex subsp. simplex
• Thymus moesiacus Velen.
• Scabiosa columbaria subsp. portae (Huter) Hayek
Fourteen taxa resulted new for the regional flora of Campania:
• Bromus hordeaceus subsp. pseudothominei (P.M.Sm.) H.Scholz
• Carex tomentosa L.
• Hordeum geniculatum All.
• Juncus tenageia subsp. tenageia
• Knautia lucana Lacaita & Szabó
• Koeleria lucana Brullo, Giusso & Miniss.
• Pilosella piloselloides subsp. praealta (Gochnat) S.Bräut. & Greuter
• Ranunculus peltatus subsp. peltatus
• Rosa mollis Sm.
• Rubus incanescens L.
• Sanguisorba officinalis L.
• Scabiosa columbaria subsp. portae (Huter) Hayek
• Silene italica subsp. sicula (Ucria) Jeanm.
• Trifolium phleoides Willd.
Finally, five taxa were confirmed for Campania:
• Alisma lanceolatum With.
• Alopecurus aequalis Sobol.
• Myosotis nemorosa Besser
• Sabulina glaucina (Dvořáková) Dillenb. & Kadereit
• Vicia serratifolia Jacq.
The high number of taxa surveyed in a few days and in a limited number of sampling localities undoubtedly indicates the high level of biodiversity of the Maddalena Mountains, an area that until now did not attract explorations by botanists.
The number of new or confirmed units at the regional level underlines the fact that floristic knowledge of Basilicata and Campania cannot yet be considered satisfactory, despite numerous publications produced in recent years (e.g.
We are grateful to Anna Scoppola, Dino Marchetti, Gianniantonio Domina for the determination of some critical samples. Giovanna Potenza and Emmanuele Farris kindly collaborate to organize the field trip. A special thanks to Michele Cicerchia and his family for the warm hospitality at the Hotel Eden in Brienza. The visit to the hill of Caracciolo’s Castle was a courtesy of the Municipality of Brienza. We should also like to thank Fernando Lucchese and Alfred Mayer for having hosted and supported the working days for review of the critical samples at the University of Roma Tre. Michela Marignani has kindly revised the English language. We are grateful to Francesco Roma-Marzio and Gianniantonio Domina for the improvements to the first draft of the paper.
