Lectotypification of six names of species of Scabiosa S.L. (Caprifoliaceae) endemic to north Africa and related taxonomic notes
2020
As part of an ongoing project for the investigation of the Algerian-Tunisian flora, six names of species of Caprifoliaceae subfam. Dipsacaceae, endemic to central and western North Africa, described in the 19th and 20th Centuries under the genus Scabiosa, are here lectotypified. They are: Scabiosa camelorum Cosson & Durieu, Scabiosa cartenniana Pons & Quézel, Scabiosa daucoides Desf., Scabiosa farinosa Cosson, Scabiosa parielii Maire, and Scabiosa robertii Barratte. Taxonomic notes, distributisson and new unpublished data about plant phenology of these taxa are given.
Silene crassiuscula (Caryophyllaceae), a new species from Sicily
2015
Silene crassiuscula,, a new species of S. sect. Dipterosperma, is described and illustrated from North-Western Sicily. It is an annual halophyte with succulent growing on carbonatic or calcarenitic rocks of coastal stands. From the morphological point of view , S. crassiuscula appears to be similar to the species belonging to the S. colorata group especially to S. nummica, from Sardinia, from which it differs in several features chiefly regarding the habit, leaves, inflorescences, floral pieces and seed micro-morphology. An analytical key of the taxa belonging to this section is also provided.

2020
Micromeria Bentham (1829: sub t. 1282) (Lamiaceae) is a monophyletic and taxonomically intricate genus, represented by nearly 70 species. These are distributed from the Macaronesian-Mediterranean region to southern Africa, India, and China (Morales 1991b, Govaerts 1999, Harley et al. 2004, Bräuchler et al. 2005, 2008; Puppo & Meimberg 2015, Puppo et al. 2014, 2015).
<strong>Nomenclatural notes on Fabaceae described from Sicily</strong>
2021
A note about some taxa in Anthyllis and Trifolium (Fabaceae) described from Sicily is presented. Concerning Trifolium, we provide the lectotypification of the name T. pratense var. semipurpureum (≡ T. pratense subsp. semipurpureum), using a specimen preserved at PAL (Todaro’s collection). Concerning the Lojacono-Pojero’s name Vulneraria heterophylla var. parvula, it is lectotypified by a specimen at G. A neotype at NAP is proposed for the Gussone’s name Vulneraria heterophylla var. albiflora. As this latter name is applied to a taxon accepted here at specific rank, a new combination is validated. On the contrary, A. heterophylla var. parvula is considered as a new heterotypic synonym of Ant…
Typification of the name Galatella sorrentinoi (Asteraceae)
2020
The name Galatella sorrentinoi Todaro (Asteraceae) is lectotypified with a specimen housed in the Herbarium Mediterraneum Panormitanum (PAL). The specimen selected as the lectotype agrees with protologue and with the current usage of the name.
Networks of Seed Storage Protein Regulation in Cereals and Legumes at the Dawn of the Omics Era
2012
BAP GEAPSI CT2 (BAP); International audience; Finely regulated and orchestrated events occur during seed development and germination in different cell organelles (mitochondria, peroxisomes, plastids, vacuoles, endoplasmic reticulum, oil bodies and nuclei). Therefore, some of the ongoing investigations pass through sub-cellular organelle purifications for a deeper comprehension of these complex developmental processes. In seed biology, recent ambitious efforts in proteomics have been directed toward organelle isolation from seeds and high-throughput protein separation and identification by mass spectrometry at defined developmental stages. The construction of reference maps allowed identifyi…
Typification of seven names in the genus Antirrhinum (tribe Antirrhineae, Plantaginaceae)
2021
The typification of seven names in the genus Antirrhinum (tribe Antirrhineae, Plantaginaceae): A. charidemi, A. latifolium, A. molle var. mollissimum, A. molle var. marianum, A. sempervirens, A. siculum, and A. valentinum is discussed. The designation of the nomenclatural types is based on the consultation of original material and the literature cited in the respective protologues. The names are lectotypified using specimens from BC, C, MA, and an illustration of Boccone published in 1697. An epitype is also designated for A. latifolium due to ambiguity in the interpretation of the lectotype. The name A. siculum is neotypified from a specimen preserved at VAL, and a second-step lectotypific…
Dianthus borbonicus (Caryophyllaceae), a new species from Sicily
2015
Dianthus borbonicus a new species occurring in North-Western Sicily is described and illustrated. It is a rare chasmophyte belonging to the D. sylvestris group, which is exclusive of a rupestrian stand near Rocca Busambra (Ficuzza). Its macro- and micromorphological features (seed testa sculptures, and leaf anatomy), ecology, conservation status and a comparison with the related species are provided too.
<p><strong>Typification of the name <em>Galatella sorrentinoi </em>(Asteraceae)</strong></p>
2020
Tripolium sorrentinoi (Todaro 1858: 42) Raimondo & Greuter (2005: 59) (Asteraceae) is a species endemic to Sicily. In this island, it grows on badlands in the Palermo, Enna, Caltanissetta, and Agrigento Provinces, between the coast and the hinterland mountains. Its phytogeographical interest is remarkable because it occurs in selective habitats, where it is often the sole phanerogamic inhabitant. Due to its small population size and to a continuing decline of mature individuals, T. sorrentinoi was assessed as “Vulnerable” (VU) according to the IUCN criteria (Domina & Troia 2016).
Epitypification of Hagaea alsinifolia (Polyycarpon tetraphyllum subsp. Alsinifolium, Caryophyllaceae)
2018
As part of the ongoing studies on the genus Polycarpon Linnaeus (1759: 859, 881) (see e.g., Iamonico 2015a, 2015b, 2015c, Iamonico & Domina 2015), and on the Italian loci classici (see e.g., Peruzzi et al. 2015, Brundu et al. 2015, Domina et al. 2016, Di Gristina et al. 2017, Domina et al. 2017, 2018a, 2018b), we present here a note regarding Hagaea alsinifolia Bivona-Bernardi (1815: 7–8) [currently accepted (see Bartolucci et al. 2018) as Polycarpon tetraphyllum Linnaeus (1759: 881) subsp. alsinifolium (Biv.) Ball (1877: 370)].
