The small genus Bellardiochloa Cmov. (Poaceae) has intermediate features between Poa L. and Festuca L., but it is well differentiated both from a morphological and molecular viewpoint. In Sicily, Bellardiochloa is represented by two rather critical and yet not well investigated populations occurring on Mt. Etna and Mado-nie massif, respectively. Morphological and taxonomical studies together with no-menclatural considerations allowed to distinguish two morphologically well differentiated orophilous, vicarious taxa, which may be considered as subspecies of B. variegata (Lam.)

Abstract
The small genus Bellardiochloa Cmov. (Poaceae) has intermediate features between Poa L. and Festuca L., but it is well differentiated both from a morphological and molecular viewpoint. In Sicily, Bellardiochloa is represented by two rather critical and yet not well investigated populations occurring on Mt. Etna and Mado-nie massif, respectively. Morphological and taxonomical studies together with no-menclatural considerations allowed to distinguish two morphologically well differentiated orophilous, vicarious taxa, which may be considered as subspecies of B. variegata (Lam.) Kerguélen. These are B. v. subsp. nebrodensis (Ascherson & Graeb-ner) C. Brullo, S. Brullo, Giusso & Sciandrello comb, et stat. nov. from Madonie massif, and B. v. subsp. aetnensis (C. Presl) Glardina & Raimondo from Mt. Etna. Synonyms, descriptions, drawings of morphological details and distribution are provided for these taxa and also for B. v. subsp. variegata. In Greece only B. v. subsp. variegata occurs.File | Dimensione | Formato | |
