First record for the flora of Italy and lectotypification of the name Linum elegans (Linaceae)
2017
Linum elegans has been detected in calcareous rocky garrigues on the Gargano promontory (Apulia, SE-Italy), representing the first record for the Italian flora and the first one outside the Balkan Peninsula. The geographical disjunction may provide evidence for past amphi-Adriatic/amphi-Ionic terrestrial connections. The population found was ascribed to L. campanulatum in the past. As a consequence, a comparison between these two species is undertaken. Furthermore, the name L. elegans is here lectotypified on a specimen preserved at G, and the IUCN assessment of the species in Italy is briefly discussed.
Typification and taxonomic remarks on five species names in Cytisus (Fabaceae)
2020
This paper deals with the typification and taxonomy of five Mediterranean Cytisus species. Cytisus affinis, C. candidus, and C. spinescens nom. illeg., non Sieber ex Spreng. were described from Sicily by Karel Bořivoj Presl, Cytisus spinescens was described from Apulia (southern Italy) by Curt Polycarp Joachim Sprengel, and C. villosus was described from southern France by Pierre André Pourret (1788). Lectotypes are here designated for Presl and Sprengel’s names. A neotype is designated for C. villosus. The taxonomic revision of these five names confirmed that C. villosus Pourr. (= Cytisus affinis C.Presl) is the name to be used for the species occurring in the large part of the Mediterrane…
Typification of the Mediterranean Endemic Deep-Water MacroalgaLaminaria rodrigueziiBornet (Laminariaceae, Phaeophyceae)
2016
Abstract Laminaria rodriguezii Bornet is a deep-water brown alga endemic of the Mediterranean Sea. Lectotypification of Laminaria rodiguezii has been based on both Bornet's protologue and the original material housed at the cryptogamic collections of the Museum National d'Histoire Naturelle de Paris (PC).
A revision of the typification of some names in the seagrass genera Amphibolis, Cymodocea, Halodule and Syringodium (Cymodoceaceae)
2020
The typification of eight names of species currently included in the family Cymodoceaceae is revised in order to contribute to their nomenclatural stability. The previously designated lectotype of Ruppia antarctica Labill. (≡ Amphibolis antarctica (Labill.) Sond. & Asch.) is cited. Lectotypes are designated here for Zostera nodosa Ucria (≡ Cymodocea nodosa (Ucria) Asch.), Cymodocea rotundata Asch. & Schweinf., Caulinia serrulata R. Br. (≡ Cymodocea serrulata (R. Br.) Asch. & Magnus), Halodule bermudensis Hartog, Diplanthera pinifolia Miki (≡ H. pinifolia (Miki) Hartog) and Cymodocea isoetifolia Asch. (≡ Syringodium isoetifolium (Asch.) Dandy). A neotype is designated here for Z. uninervis F…
An inventory of the names of native, non-endemic vascular plants described from Italy, their loci classici and types
2019
The census of the loci classici of 1,227 native, non-endemic vascular plants described from Italy is here presented and described. The effective place of publication of accepted names, basionyms and homotypic synonyms were identified and critically verified. The geographic information on the loci classici was excerpted from the protologues, as well as information on typification for the taxa described before 1 January 1958. The names without a holotype are 1,165. For 591 names a lecto- or neo-typification is available in literature, while 572 currently accepted taxa still need a type designation. For ten of these names showing previous ineffective typification, nomenclatural types are desig…
The naming and typification of the breadfruit, Artocarpus altilis, and breadnut, A. camansi (Moraceae)
2018
The historical background and typification of the widely distributed and highly appreciated breadfruit tree, Artocarpus altilis (≡ Sitodium altile; Moraceae), and breadnut, A.camansi, is discussed. Sitodium altile is lectotypified selecting a watercolour painting by Sydney Parkinson made in Tahiti in 1769, during James Cook's first voyage around the world (1768–1771) in HMS Endeavour, and preserved at the Natural History Museum of London. A specimen from E. D. Merrill's “illustrative specimens” of Blanco's Philippine plants in the United States National Herbarium is designated as the neotype for A.camansi.
Typifications of the Linnaean name Equisetum hyemale and E. ×moorei (Equisetaceae)
2017
The lectotypes of the names Equisetum hyemale Linnaeus (1753: 1062) and E. ×moorei Newman (1854: 19) (Equisetaceae) are designated. Previously, a neotype for E. hyemale was selected by Hauke in 1962 from a specimen kept at LINN. However, this typification is rejected since there are two original elements that may contribute to a correct lectotypification of the name. Therefore this choice is ineffective and should be rejected. An illustration from Mattioli (1586) is designated as the lectotype. On the other hand, in order to avoid any ambiguity in the interpretation of the lectotype, an epitype is also selected. A lectotype for E. ×moorei, the putative hybrid between E. hyemale and E. ramos…
Two complex typifications and a new name to unravel Ulota germana sensu Malta non (Mont.) Mitt. (Orthotrichaceae)
2020
Ulota germana is an epiphytic moss moderately common in oceanic areas of Patagonia (southern South America), one of the regions of the world where Ulota reaches a peak of diversity. It is easily recognized by very long perichaetial leaves, which reach the capsule when wet, an endostome of eight segments and verrucose spores. In Nikolajs Malta's revision of South American Ulota, a species was described under this name with apparently similar long perichaetial leaves and spores but with a 16-segment endostome, an uncommon character in this genus. No further references to this particular combination of traits are found throughout the literature of South American Ulota. In the same work, Malta …
Multivariate morphometric analysis of the Stipa turkestanica group (Poaceae: Stipa sect. Stipa)
2015
Based on numerical analyses of macromorphological characters (cluster analysis, principal coordinate analysis and principal component analysis), scanning electron microscopy observation of lemma and lamina micromorphology, as well as field observations, five taxa belonging to the Stipa turkestanica group have been recognized in the mountain area of Central Asia. They are S. turkestanica subsp. turkestanica, S. turkestanica subsp. trichoides, S. macroglossa subsp. macroglossa, S. macroglossa subsp. kazachstanica and S. kirghisorum. As a result of this study, we propose one new combination, S. macroglossa var. pubescens, and designate lectotypes for S. turkestanica subsp. trichoides and S. ma…
Geometrical deviation of end-of-life parts as a consequence of reshaping by single point incremental forming
2021
AbstractPutting in place circular economy strategies is an urgent challenge to face. In this scenario, manufacturing processes play a relevant role as efficient material reuse enabler. Scientists have to make an effort either to find new process or to rethink old process to reprocess end-of-life (EoL) component to recover both material and functions. In this paper, single point incremental forming (SPIF) process is used for reshaping sheet metal EoL components. The entire process chain was replicated including both deep drawing process (to imitate the end-of-life component) as well as SPIF operations (to obtain the reshaped components). The geometrical deviation as a consequence of SPIF ope…
