As part of ongoing studies on Fabaceae Lindl. (see e.g., Bernardo et al. 2019, Iberite et al. 2017, Iamonico et al. 2021), we here present a note about the names Onobrychis tenoreana Lacaita (1911: 276), O. laconica Orph. ex Boissier (1872–1873: 530) [= O. alba (Waldstein & Kitaibel 1803–1805: 111) Desvaux (1814: 83) subsp. pentelica (Haussknecht 1887: 71) Nyman (1889: 99)], and O. pentelica. The research is based on both analysis of the relevant literature and examination of specimens at BM, FI, JE, MPU, and P (Thiers 2021 onwards).

The systematic relationships between Carduus brutius and its putatively relative taxa, i.e. Carduus affinis and C. defloratus subsp. carlinifolius , were assessed by means of morphological, morphometric and karyological analyses. Our results highlighted a diploid status (2n = 2x = 22) for all the three involved taxa and a higher morphological similarity between C. brutius and C. affinis , which are also completely allopatric (but collectively sympatric with C. defloratus subsp. carlinifolius ). The names Carduus affinis Guss., C. affinis var. brutius Fiori, C. affinis var. vulturius Fiori and C. affinis f. pollinensis Fiori were typified. At the present state of knowledge, a subspecific status seems the most appropriate for C. brutius , as C. affinis subsp. brutius . This taxon can be regarded as schizoendemic, restricted to southern Italy (Montea-Caramolo mountain area, Calabria).

A morphometric and karyological study of several populations of Genista sericea , a northern Illyrian amphiadriatic species, with a disjunct distributional area centered on Pollino Massif (southern Italy), has been undertaken, based on herbarium specimens and field research. Morphometric analysis allowed to individuate three distinct groups of populations which are here attributed to three taxa at subspecific level. One of them is here newly described: G. sericea subsp. pollinensis , endemic to northern Calabria in Pollino and neighbouring areas of Basilicata. The taxonomic status of G. sericea var. rigida was re-evaluated and a name of a new rank is proposed: G. sericea subsp. rigida (occurring in southern Illyria), while subsp. sericea is a southeastern Alpine northern Illyrian taxon. The names G. sericea and G. sericea var. rigida are lectotypified. Karyologically, all the taxa are characterized by the same somatic number 2n = 48, sometimes with B chromosomes (up to four).
