Pyrus magyarica was considered as a “superendemic” species of the Carpathian Basin for a long time; however, despite its presumed significance, doubts about its taxonomical status have been raised. The confusions originate from the invalidity of the description and the lack of type material. Latter interpretations are not consistent and contradict the description of the species in the protologue. The authors attempted to get access to the original material of the taxon, but no vouchers or living specimens that correspond to the protologue were found; herbarium specimens assigned as P. magyarica mostly refer to P. pyraster. Based on the available records, P. magyarica cannot be clearly defined and re-described; thus we propose to leave off the use of the name P. magyarica as it has no clear content.

During recent herbarium and field studies three names of Rubus sect. Corylifolii ser. Subcanescentes were re-assessed. Rubus macrostemonides was typified with a neotype specimen from Salzburg (Austria), and its identity with R. baruthicus was shown (the previous name has the priority). Its presence at the Austrian locus classicus was confirmed also recently, this locality represents the easternmost occurrence of the species. The name R. holosericeus was (mis)applied for a long time for a widespread taxon occurring southeast of the Alps that is not at all present in the original material. This name was lectotypified with a specimen from Styria (Austria) here as a hitherto overlooked regional species recently recorded in Austria, Hungary and Slovenia. The taxon that was formerly (mis)identified as R. holosericeus has proven to be identical to R. semitomentosus, which is lectotypified here with a specimen from Hungary. For both taxa clarified here is, beside a circumstantial assessment of the type material, an improved morphological characterization and circumscription of distribution and habitats presented.

Based on examination of herbarium specimens (including type material), we found that Delphinium calthifolium (Ranunculaceae), described from northern Sichuan in China, is conspecific with D. sinovitifolium, a species known only from its type material and misunderstood for a long time. We therefore place D. calthifolium in synonymy with D. sinovitifolium herein.

Researchers in phylogenetic systematics typically choose a few individual representatives of every species for sequencing based on convenience (neighboring populations, herbarium specimens, samples provided by experts, garden plants). However, few studies are based on original material, type material or topotypic material (living specimens from the locality where the type material was collected). The use of type or topotypic material in phylogenetic studies is paramount particularly when taxonomy is complex, such as that of Antirrhinum (Plantaginaceae). In this paper, we used topotypic materials of Antirrhinum at the species level (34 species proposed by previous authors), 87 specimens representing the species distributions and >50,000 informative nucleotide characters (from ∼4,000 loci) generated by the genotyping-by-sequencing (GBS) technique: (i) to test two explicit taxonomic hypotheses widely followed by local taxonomic treatments; (ii) to robustly estimate phylogenetic relationships; (iii) to investigate the evolution of key morphological characters and biogeographic centers of differentiation. Two GBS phylogenies based on two datasets (87 localities and 34 topotypic specimens) revealed that: (1) Sutton’s (1988) taxonomic account is the most congruent with phylogenetic results, whereas division of Antirrhinum into three major clades disagrees with Rothmaler’s (1956) infrageneric classification; (2) monophyly of populations currently included in the same species is primarily supported; (3) the historically recognized Antirrhinum majus group is not monophyletic; (4) sister-group relationships are robust for eight species pairs; (5) the evolutionary radiation of 26 species since the Pliocene is underpinned given a high rate of diversification (0.54 spp. Myr–1); (6) a geographic pattern of speciation is reconstructed, with northern Iberia as the center of early diversification followed by more recent speciation in southeastern Iberia; and (7) multiple acquisitions of key taxonomic characters in the course of Antirrhinum diversification are strongly supported, with no evidence of hybridization between major clades. Our results also suggest incipient speciation in some geographic areas and point to future avenues of research in evolution and systematics of Antirrhinum.

Trifolium multistriatum (T. sect. Vesicastrum subsect. Mystillus) is a neglected species currently considered as a synonym of T. setiferum or T. rumelicum. The identity of T. multistriatum compared to the species closely related is briefly discussed and its distinct autonomy is highlighted based on the analysis of relevant literature and herbarium specimens, including the type material. The holotype is indicated here for its name based on an exsiccatum belonging to the gathering cited in the protologue, which is preserved at L. Other relevant related material is preserved at PAD and TSM. The distribution area of T. multistriatum includes Western Balkan Peninsula and Italy. The studied material was mostly collected long time ago. For Southern Italian territory, the most recent records date back to the mid 1900s.

Based on critical observations on herbarium specimens (including type material) and living plants in the wild from its type locality, we demonstrate that Thalictrum kangdingense, recently described from Kangding county in western Sichuan province, China, is readily distinguishable from T. xinningense by an array of morphological characters but is actually conspecific with T. megalostigma, a species with its type locality also in Kangding. We therefore reduce T. kangdingense to the synonymy of T. megalostigma herein. The morphological distinction between T. baicalense and T. megalostigma is also clarified.

Based on examination of herbarium specimens (including type material), we demonstrate that Delphinium breviscaposum and D. filibracteolum (Ranunculaceae), both described recently from northwestern Yunnan in China, are conspecific with D. ceratophorum and D. bulleyanum, respectively, two species very common in northwestern Yunnan. We therefore synonymize D. breviscaposum and D. filibracteolum herein. Second step lectotypifications are proposed for both D. bulleyanum and D. ceratophorum.

Delphinium ellipticovatum, D. tianshanicum and D. winklerianum (Ranunculaceae) share some important characters in leaf division, pedicel pubescence and the shape of the spur of upper sepals. They have been considered to be different mainly in the characters of bracteoles (shape, size, indumentum, and position on pedicels). Our critical observations on herbarium specimens (including type material) and living plants, together with numerical analyses of the bracteole characters within and between populations of the species in question, have demonstrated that, in addition to D. kuanii previously already synonymized with D. winklerianum, both D. ellipticovatum and D. tianshanicum are also indistinguishable from D. winklerianum. We therefore further place D. ellipticovatum and D. tianshanicum also in synonymy with D. winklerianum.

Examination of herbarium specimens (including type material) has shown that Anemone weixiensis, recently described from Weixi County in northwestern Yunnan, China, is conspecific with A. flaccida, a species widely distributed in China, Japan and Russia (Far East) and fairly common in northwestern Yunnan. We therefore place A. weixiensis in synonymy with A. flaccida. As A. flaccida belongs to A. sect. Keiskea based on molecular work, we reduce A. sect. Deinostigma, which was established to accommodate A. weixiensis, to the synonymy of A. sect. Keiskea.

Critical examination of herbarium specimens (including type material) of Cremanthodium ellisii var. roseum (Asteraceae, Senecioneae) has shown that the variety should be transferred to C. brunneopilosum. We therefore propose a new combination, C. brunneopilosum var. roseum.

Cremanthodium atrocapitatum (Asteraceae, Senecioneae) has been previously largely misunderstood, resulting in considerable taxonomic confusion involving several taxa. Based on observations of both herbarium specimens (including type material) and living plants, here we clarify the taxonomic identity of this species. The Xizang (Tibet) plants previously referred to C. atrocapitatum are described as a new species, i.e. C. bomiense. Cremanthodium campanulatum var. brachytrichum is found to be very close to C. atrocapitatum rather than C. campanulatum, and is thus treated as C. atrocapitatum var. brachytrichum.
