Abstract

In a previous contribution (1) the finding in the wild of Clinopodium minae (Lojac.) Peruzzi & F.Conti [Bas. Calamintha minae Lojac.], a critical species close to Clinopodium corsicum (Pers.) Govaerts and well distinct from Clinopodium alpinum (L.) Kuntze subsp. nebrodense (A.Kern. & Strobl) Bartolucci & F.Conti was reported. It is a critical taxon, described by Lojacono, author of the most extensive work on the Sicilian flora (2) based on the examination of the collections of the Herbarium of Palermo (PAL!) (3). In the above cited note, the specific characters as well as the taxonomic relationships with other taxa were highlighted. At the same time, the location of a small population of C. minae on the northern slopes of the calcareous system of the Carbonara, the highest mountain of the Madonie (N Sicily), was reported.Starting from this first population, field surveys have been extended to other localities of the Madonie. These have also enabled us to find C. minae also on the western slopes of Monte Quacella that, named the "Sicilian Alps" by the same Lojacono, is the richest area in mostly endemic plant species, with respect to Sicily (4).In this context, C. minae occurs on consolidated dolomite debris, in semi-shaded places, from 1450 to 1700 m, at margins of larger communities at Juniperus communis subsp. hemisphaerica (J.Presl & C.Presl) Arcang. and Daphne oleoides Schreb., together with Odontarrhena nebrodensis (Tineo) L. Cecchi & Selvi subsp. nebrodensis, Clinopodium alpinum subsp. nebrodense, Anthemis arvensis subsp. sphacelata (C.Presl) R.Fern., Carlina nebrodensis DC., Centaurea parlatoris Heldr., Helianthemum cinereum subsp. rotundifolium (Dunal) Greuter & Burdet, H. oelandicum subsp. incanum (Willk.) G.López, Hypochoeris radicata L., Jurinea bocconei Guss., Laserpitium siler subsp. siculum (Spreng.) Santangelo, F.Conti & Gubellini, Linum punctatum C.Presl, Onosma echioides subsp. canescens (C.Presl) Peruzzi & N.G. Passal., Paeonia mascula (L.) Mill., Pilosella hoppeana subsp. sicula Di Grist., Gottschl. & Raimondo, Pimpinella tragium subsp. lithophila (Schischk.) Tutin, Orchis anthropophora (L) All., Sesleria nitida subsp. sicula Brullo & Giusso, Silene italica subsp. sicula (Ucria) Jeanm., Teucrium montanum L., Thymus striatus Vahl, and some grasses.Compared with the plants from the Carbonara Mount, the population of Quacella is much richer in individuals and shows an accentuated variability, not remarked in the taxonomic analysis by Lojacono.At present, however, based on the recently collected materials, C. minae occurs on both calcareous and dolomite substrates, above 1,450 m a.s.l. Based on the collections by A. Todaro housed in PAL! and in the course of field surveys, the authors do not exclude the possible occurrence of C. minae in other carbonatic reliefs in the province of Palermo.
