The Irano-Turanian region is one of the world’s richest floristic regions and the centre of diversity for numerous xerophytic plant lineages. However, we still have limited knowledge on the timing of evolution and biogeographic history of its flora, and potential drivers of diversification remain underexplored. To fill this knowledge gap, we focus...

The identity of Lithospermum rochelii , so far known only from its type locality (Bulgaria, hills in Plovdiv town), remained hitherto uncertain. Our examination of its original material and re‐collection of the species from its locus classicus in Plovdiv town revealed its identity with Lithospermum glandulosum (syn. Buglossoides glandulosa ) descri...

Human activities are causing global biotic redistribution, translocating species and providing them with opportunities to establish populations beyond their native ranges. Species originating from certain global regions, however, are disproportionately represented among naturalized aliens. The evolutionary imbalance hypothesis posits that differenc...

On the basis of herbarium specimens and documented observations, the taxonomic confusion around Allium filidens s.l. (including A. filidentiforme) in Kyrgyzstan is resolved. The species status of A. filidentiforme is confirmed, and this species is classified in A. subsect. Crystallina, comb. nov. In Central Asia, the A. filidens group (A. subsect....

A new subshrubby C 4-species from the lowlands and foothills of India, Pakistan and SE Afghanistan, Atriplex pseudotatarica, is described and illustrated. Previously, it was incorrectly identified as A. crassifolia auct. non C.A.Mey. belonging to a distant C 3-group of the genus. A phylogenetic analysis based on nrITS and nrETS revealed its positio...

The basal monocot genus Acorus comprises essential oil-producing plants widely used in traditional medicine in various countries, including India. Acorus calamus sensu lato is a polyploid complex where the essential oil composition, to some extent, depends on the ploidy level. The literature recognizes diploids (in temperate Asia and North America)...

Heinrich Wilhelm Schott (1794-1865) was one of the pioneering researchers in the taxonomy of the species-rich monocot family Araceae. He described numerous new plant species in various genera, including Acorus, which is currently segregated as a monogeneric family and order occupying a position sister to the rest of the monocots. While describing h...

Abutilon albidum, a cryptic Saharo-Canarian species, was thought to have been last collected in 1945 in Tenerife by E.R. Sventenius. In 2019, it was rediscovered in the same area. The characteristic features of the Canarian plants are discussed, especially in relation to the morphologically similar-looking and probably closely-related species Abuti...

Salvia korolkowii (Lamiaceae) has been considered a species of highest conservation priority due to its narrow distribution and isolated taxonomic position. The species has been known from Uzbekistan and, questionably, Kyrgyzstan and treated as endemic to the Western Tian-Shan. Its modern conservation status according to the IUCN Criteria has not b...

For a long time, the systematics of Atriplex was based solely on morphological characters and leaf anatomy. The latest worldwide phylogenetic study of Atriplex significantly improved our knowledge about the relationships within the genus, but a new classification has not been put forward thus far. Here we re-evaluate the taxonomy of C 4 -species of...

The concept of epitypes was introduced to resolve the cases when the primary type of a plant name (holotype, lectotype or neotype) is demonstrably ambiguous and cannot be identified to the appropriate taxonomic level. In spite of the original intention, epitypes have been widely used as a means to complement the primary type with other morphologica...

Biodiversity inventory is critically important due to the increasing anthropogenic pressure and destruction of habitats, as well as the associated increasing threat of extinction of species occurring in a certain area or even globally. Plant diversity information is fundamental for biodiversity research and conservation. In this regard, there is an...

A new genus, Caucasoseris, is established to accommodate Prenanthes abietina, a species of hitherto uncertain systematic position distributed in the western Caucasus and northeasternmost Turkey in montane conifer and mixed forests.

Background: We continue the inventory of alien vascular plants of Kyrgyzstan, with emphasis on the time and pathways of introduction of the species and their current status in the territory. Each taxon is discussed in the context of plant invasions in Central Asia. This work is a further development of the preliminary checklist of alien plants of...

The protologue of Iris orchioides described and illustrated a juno iris of uncertain provenance, which was characterised by an elongated stem, glossy green leaves which were not prominently folded, and yellow flowers with unwinged claws of the outer tepals. When the native juno irises of Central Asia had been taxonomically classified, the name I. o...

Plants with golden yellow flowers were originally described from the Pamir-Alai as Iris orchioides but subsequently considered a colour form of I. bucharica, whereas the name I. orchioides was erroneously transferred to a yellow-flowered species of the Tian-Shan. The golden-flowered plants differ from the type of I. bucharica (which is prominently...

Based on the protologue data, Calamagrostis neglecta Ehrh. is a legitimate name, which is correct for the species otherwise known as C. stricta Timm.
