No full textIn our recent paper, we noticed a mistake concerning figure 2 (Di Pietro et al. 2021: 93). According to the caption, figure 2 should represent the sheet FI051890 (a lectotype of Sesleria nitida var. tenoreana f. visianii). In fact, in the place of the sheet FI051890, a figure containing two herbarium specimens deposited in PAD (PAD-HD00955 and PAD-HD00956) was erroneously published. These two PAD specimens were discussed in the paper (Di Pietro et al. 2021: 94) where it was highlighted that these could not be considered with certainty as original material for Sesleria nitida var. tenoreana f. visianii Pampanini (1917: 4). We here, correct the mistake and publish the image of lectotype of Sesleria nitida var. tenoreana f. visianii (FI051890, Fig. 1). Copyright © 2021 Magnolia Pres

No full textPhytosociological features of Sesleria calabrica (Poaceae), an endemic species to Pollino-Orsomarso mountains (southern Italy)
No full textSesleria calabrica (Deyl) Di Pietro is a species belonging to the collective group of S. juncifolia s.l. which has been described recently for southern Italy where it is restricted to the Pollino-Orsomarso massifs. In this area S. calabrica is widespread between 1200 and 2280 m a.s.l where it is the dominant species in two grassland types, Jurineo mollis-Seslerietum calabricae ass. nov. (lower montane belt) and Anthyllido atropurpureae-Seslerietum calabricae ass. nov. (subalpine belt) which belong respectively to Festuco-Brometea and Elyno-Seslerietea classes. The presence of a southern Italy endemic sub-alliance of Seslerion apenninae is hypothesised

Neotypification of the name Plantago alpina (Plantaginaceae)
No full textThe typification of the Linnaean name Plantago alpina (Plantaginaceae) is discussed. Plantago alpina is a critic taxa of the European flora and it has been often confused with other taxa such as P. serpentina, P. recurvata, P. holosteum. To provide a precise reference to this taxon, a specimen from the Haller
Herbarium (GOET) is designated as the neotype on the basis of a long research which has involved Herbarium research and the expertise on the high-altitude Flora and vegetation of Romeo Di Pietro.The typification of the Linnaean name Plantago alpina (Plantaginaceae) is discussed. A specimen from the Haller
Herbarium (GOET) is designated as the neotype
About the application of the Linnaean name Plantago latifolia (Plantaginaceae)
No full textPlantago Linnaeus (1753: 112) (Plantaginaceae) is a genus including 200–250 species distributed throughout the temperate
zone and the high-elevation tropical regions (Rahn 1996, Rønsted et al. 2002).
This genus is critical from the taxonomical point of view, showing a high morphological variability and plasticity
(Anderson et al. 2013), a reduced number of morphological characters (Rahn, 1996) and a phylogenetic history not completely
resolved (Rønsted et al. 2002, Ishikawa et al. 2009, Tay et al. 2010, Meudt 2011). In addition, recently new species were
discovered and described (Hassemer & Baumann 2014, Hassemer et al. 2014, Hassemer 2016, Hassemer & Rønsted, 2016),
and new combinations were proposed (Hassemer & al., 2015). Also nomenclature of the genus is problematic and several
names were recently investigated (Di Pietro et al. 2013, Di Pietro & Iamonico 2014a, 2014b, Iamonico et al. 2017).
As part of an ongoing study on the genus Plantago (Di Pietro et al. 2013, Di Pietro & Iamonico, 2014a, 2014b,
Hassemer et al. 2017, Iamonico et al. 2017), we present here a note concerning the Linnaean name Plantago latifolia, which
appears still untypified and is considered by Jarvis (2007) as a name with uncertain application
New dry grassland associations from the Ausoni-Aurunci mountains (Central Italy) - Syntaxonomical updating and discussion on the higher rank syntaxa
No full textA phytosociological study on the most extensive dry grassland communities of the coastal limestone massif of the Ausoni-Aurunci mountains (southern Latium, central Italy) is here presented. Violo pseudogracilis-Koelerietum splendentis ass. nova is restricted to the montane belt of the Aurunci mountains where it is dynamically related to the mesophilous Ostrya carpinifolia or Fagus sylvatica woodlands. Helichryso italici-Brometum erecti ass. nova is found within the upper hilly and submontane belt of both the Ausoni mountains (typical aspect) and the Aurunci mountains (subassociation saturejetosum montanae), where it is dynamically related with termophilous Ostrya carpinifolia woods and mesophilous Quercus ilex woods. Helichryso-Brometum is differentiated from Violo-Koelerietum in that it has a higher incidence of the steno-Mediterranean therophytic component. As far as the higher rank syntaxa are concerned, in this study the following changes were made in accordance with the rules of ICPN: the name Phleo ambigui-Bromion erecti Biondi et al. 1995 was considered invalid due to the invalidity of its nomenclatural type Asperulo purpureae-Brometum erecti. In contrast, the validity of the old name Cytiso spinescentis-Bromion erecti Bonin 1978 was demonstrated and its nomenclatural type, Lavandulo-Asphodelinetum luteae Bonin 1978, was lectotypified. Thus Cytiso spinescenti-Bromion erecti Bonin 1978 henceforth substitutes Phleo ambigui-Bromion erecti (nom. inval.) as the syntaxonomical reference for the endemic alliance of the hilly and montane limestone dry grasslands of the central and southern Apennines. Cytiso-Bromion is here divided into two suballiances: Sideritidenion italicae Biondi et al. 1995, Phleo ambigui-Bromenion erecti Biondi et al. ex Di Pietro suball. nov. Cytiso-Bromion belong to the new suborder Festuco circummediterraneae- Seslerienalia nitidae (Ubaldi 2003) stat. nov. and to the order Artemisio albae-Brometalia erecti Ubaldi ex Mucina & Dengler 2009. New and updated packages of characteristic and differential species for both Cytiso spinescenti-Bromion erecti and its related suballiances are proposed. Furthermore the validity of the name Astragaletum calabrici Giacomini & Gentile ex Bonin 1978, was proved and the association lectotypified. This association, which was previously included in Cytiso-Bromion erecti, is moved into Koelerio brutiae-Astragalion calabrici. Finally some interesting coenological and syndynamical similarities with Scorzonero-Chrysopogonetalia western Dalmatia submediterranean dry pastures are discussed
Taxonomical features of Sesleria calabrica (Poaceae), a neglected species from southern Italy.
No full textA taxonomic study of the Sesleria juncifolia complex in the Italian Peninsula is presented, with a focus on southern Italian populations here named as Sesleria calabrica (DEYL) DI PIETRO comb. nov. et stat. nov. Karyological, morphological and anatomical characters were used for comparative analyses with populations of closely related species, such as S. juncifolia SUFFREN and Sesleria apennina UJHELYI occurring in the Italian Peninsula. Multivariate and univariate morphometric analyses, and qualitative morphological characters showed a distinct position of S. calabrica. Populations of S. calabrica differ in respect to various morphological characters of leaf and spikelet, such as the glume, lemma and palea length, stem length, the leaf sheath, leaf width, leaf thickness, and the total number of vascular bundles. Furthermore, previous karyological studies demonstrated that all the populations of both S. juncifolia and S. apennina examined are octoploid (2n=8x=56), whereas S. calabrica was found to be dodecaploid (2n=12x=84). S. calabrica is strictly confined to the Pollino massif and the Orsomarso mountains in southern Italy, which represent the southernmost limit of the Sesleria juncifolia complex distribution area both in Italy and in Europe. In addition to S. juncifolia and S. calabrica, the recognition of S. apennina as a taxon distinct from S. juncifolia is supported, at least for the area of the Apuan Alps
