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…
<p><strong>In BOLD we trust? A commentary on the reliability of specimen identification for DNA barcoding: a case study on burrower bugs …
2016
An assessment was performed regarding the accuracy of various types of data deposited in the Barcode of Life Data system (BOLD) related to the true bug family Cydnidae (Hemiptera: Heteroptera). Taxonomic nomenclature and classification, identification reliability, and the correctness of the data provided in the "Taxon description" were analyzed and commented on with respect to both available versions of the BOLD system, i.e. version 3 and beta version 4. Numerous mistakes in taxonomy, the relevance of the taxa names, and species misidentifications in BOLD version 3 were found and, more importantly, similar errors were detected in BOLD version 4 as well. We suggest that if the BOLD system is…
Vindication of Ulota pygmaeothecia (Orthotrichaceae, Bryophyta)
2017
Ulota pygmaeothecia (Müll.Hal.) Kindb. and Ulota luteola (Hook.f. & Wilson) Wijk & Margad. are two epiphytic mosses from the evergreen Magellanic rainforests of southern South America. Both mosses have been considered as distinct species since their original description, with their specific status retained following the comprehensive review by Nicolajs Malta of South American Ulota (1927). Recently the synonymization of U. pygmaeothecia and U. luteola was proposed (Wang & Jia 2016), based mainly on the similarities stated in the protologues and the study of the available type specimens of U. pygmaeothecia and U. fulvella, as the type materials of U. luteola were lost in the mail…
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…
A Systematic Nomenclature for the Drosophila Ventral Nerve Cord.
2020
Drosophila melanogaster is an established model for neuroscience research with relevance in biology and medicine. Until recently, research on the Drosophila brain was hindered by the lack of a complete and uniform nomenclature. Recognizing this, Ito et al. (2014) produced an authoritative nomenclature for the adult insect brain, using Drosophila as the reference. Here, we extend this nomenclature to the adult thoracic and abdominal neuromeres, the ventral nerve cord (VNC), to provide an anatomical description of this major component of the Drosophila nervous system. The VNC is the locus for the reception and integration of sensory information and involved in generating most of the locomotor…
The Libyan Collections in FI (Herbarium Centrale Italicum and Webb Herbarium) and Studies on the Libyan Flora by R. Pampanini – Part 2
2016
This work is the continuation of Part 1, published in 2015, and comprises the reconstruction of the original collections of new taxa described by R. Pampanini and other botanists and, where possible, typification of the new names and taxonomical updating. The material studied for the most part concerns Libyan specimens held in the FI and FI-W herbaria but in some case also K, LD, MPU, P, PAD, PAL, ULT. Other material, which Pampanini studied in Florence was subsequently conserved in other herbaria. Specimens belonging to 21 families have been examined, from the Najadaceae to Zygophyllaceae. As well as typification, bibliographical data have been provided for those already typified. In this …
Shifting urban namescapes: street name politics and toponymic change in a Romanian(ised) city
2019
Abstract Street names express the spatial materialisation of nominative discourses articulated and deployed by the powerful in their politicisation of the urban landscape with self-legitimising ideological values, political symbols and historical narratives. Using an approach grounded upon the theoretical principles of critical toponymies, this paper sets out a longitudinal perspective on the politics of street nomenclature in Hermannstadt/Sibiu (Romania). For this purpose, a dataset comprising the complete historical record of street names in Sibiu between 1829 and 2018 was constructed. The analysis focuses on capturing the ethnopolitics played out at the level of the city's street names t…
Lectotypification of Arnica montana L. (Asteraceae)
2021
A lectotype for Arnica montana L. (Asteraceae) is designated from Linnaeus’ original material preserved in the UPS-BURSER herbarium.
Lectotypification of two Linnaean plant names
2019
The typification of two Linnaean names (Asphodelus luteus, Cynomorium coccineum), applicable to species described from Sicily, is discussed. A specimen from L (Herb. Van Royen) and an illustration by Micheli are designated as lectotypes. For Cynomorium coccineum, an interpretative epitype is also designated.
