Twenty-three new combinations (Lolium adzharicum, L. ×aschersonianum, L. atlantigenum, L. ×brinkmannii, L. chayuense, L. ×czarnohorense, L. duratum, L. ×elongatum, L. ×fleischeri, L. font-queri, L. formosanum, L. ×holmbergii, L. interruptum, L. interruptum subsp. corsicum, L. ×krasanii, L. liangshanicum, L. mairei, L. letourneuxianum, L. mediterraneum, L. pluriflorum, L. ×schlickumii, L. ×subnutans, L. tuberosum) and one new name (L. scabriflorum) are proposed, fulfilling the relocation of the currently accepted Schedonorus and Micropyropsis taxa (including hybrids) under Lolium, along with three new combinations regarding natural intergeneric hybrids between Lolium and Festuca s.str., i.e. ×Festulolium (×F. hercynicum, ×F. pseudofallax, ×F. wippraense). A new epitype for Festuca arundinacea is selected, while the names F. adscendens, F. ×aschersoniana, F. ×brinkmannii, F. elongata, F. ×gigas, F. ×haussknechtii, F. ×haussknechtii f. debilis, f. diffusior, and f. strictior, F. ×holmbergii, and F. pooides are lectotypified. © International Association for Plant Taxonomy (IAPT) 2017.

The identity of Enrico (born Henry) Groves is discussed and the following four E.Groves’ names are lectotypified: Anthemis hydruntina (Asteraceae), Centaurea deusta var. nobilis (Asteraceae), Centaurea deusta var. tenacissima (Asteraceae) and Statice cancellata var. japygica (Plumbaginaceae). © 2016 Magnolia Press.

Ferula communis (L.), a plant belonging to Apiaceae, is widely present in Sardinia, Italy. Currently, interest in F. communis focuses on the presence of two chemotypes in the wild. One chemotype is poisonous to animals, whereas the other chemotype is non-poisonous. Polyphenol oxidase (PPO) has been extracted and partially purified from the two chemotypes of F. communis. The biochemical characterization of the enzymes showed significant differences. In particular, while the two PPOs were not able to use 6- and 7-hydroxycoumarin as substrates, they showed distinct specificity for 6,7- and 7,8-dihydroxycoumarin. Significant differences in the enzyme behavior towards common PPO inhibitors were also observed. In addition, activation energy and activation energy for denaturation were determined, showing significant differences between FP-PPO and FNP-PPO, particularly for denaturation kinetics. The possible roles of the two PPOs in determining differences in composition and toxicity of the two F. communis chemotypes are also discussed. © 2013 Elsevier Ltd. All rights reserved.

In the present work the presence of Paspalum notatum Flüggé (Poaceae) in Italy was reported for the fi rst time. It is a neophyte native to America, known for applications in phytoremediation. Its typifi cation, ecology and invasiveness status are also presented.

Commelina virginica, a North American xenophyte recorded in the Euro-Mediterranean area since the late 19th century, is excluded from the flora of this region. As a result of extensive literature and herbarium research, all the records of this species proved to be erroneous and referable mostly to C. communis. The first historical and misleading record of C. virginica is discussed in detail and the diagnostic morphological features actually accepted to distinguish the two species are reported. © 2014 BGBM Berlin-Dahlem.

The genus Liparis Richard (1817: 21) comprises about 320 species, broadly distributed worldwide but mainly in tropical and subtropical areas (Pridgeon et al. 2005). In Europe only the circumboreal L. loeselii (Linnaeus 1753: 947) Richard (1817: 38) occurs (Hultén & Fries 1986). Recently the new taxon L. loeselii (L.) Rich. subsp. nemoralis Perazza et al. (2012: 489) was described from northeastern Italy. It is endemic to Friuli Venezia Giulia, Veneto and Trentino-Alto Adige (Perazza & Lorenz 2013, Peruzzi et al. 2014). © 2016 Magnolia Press.

Systematics and distribution in Europe of Vitis ×novae-angliae (= V. labrusca × V. riparia, Vitaceae), a naturalized North American neophyte introduced for wine production in the 19th century, are investigated. Original identification tools are provided and diagnostic characters are discussed in detail, with special reference to leaf, fruit and seed morphology and the flavour of ripe berries. The complex of events that led to its introduction and eventually to its prohibition in Europe are also taken into account. Original morphological data regarding infructescences and seeds of related taxa are also reported. © 2015 BGBM Berlin.

New names are assigned to two ‘Euro-American’ nothospecies of Vitis originating from the artificial crossing of Euro-Mediterranean V. vinifera with two American species, employed both as rootstocks and for wine production, and spontaneously occurring in Italy and other European countries: V. ×bacoi (= V. riparia × V. vinifera) and V. ×goliath (= V. riparia × V. rupestris × V. vinifera). Original and detailed descriptions, illustrations and information on distribution and ecology are provided, along with an updated identification key. Late-season leaf pigmentation, presence/absence of phylloxera galls, ripe berries flavor, and seed morphology proved to be useful characters for the identification of the treated species and nothospecies. Nomenclatural aspects regarding V. riparia × V. vinifera are also discussed. © 2015 Magnolia Press.

Between the 18th and the early 20th century, a number of naturalized neophytes were described in Europe, outside their area of origin. Although most of the names of these taxa, discovered in a period without fast computer-mediated communication and world-wide electronic availability of taxonomic papers, today are treated as synonyms, their existence allows to shed light on a peculiar taxonomic phenomenon connected to the early stages of the European alien flora studies. In this paper we select two lectotypes and one neotype for three neophytes described in Italy, belonging to the critical graminoid genera Cyperus (C. aristatus var. boeckeleri), Echinochloa (Panicum erectum), and Eleocharis (Scirpus erraticus). The selected types are conserved at PAV-Erbario Lombardo and RO. © 2015 Magnolia Press.
