Abstract
"Based on an excellent collection, hosted in the herbarium SZB, and made by Matthias Reiter, a priest, who occupied himself intensively with the genus Hieracium in the country of Salzburg (Austria), Hieracium hypochoeroides subsp. reiteri Gottschl. is described as new for science and illustrated. It seems to be a local endemic taxon, hitherto only known from the Anlauf valley (Ankogel group) in the “Hohe Tauern”."

Szeląg Z. 2023: Hieracium lomniczkianum (Asteraceae), a new species in the H. wiesbaurianum aggregate from the Sudetes in Poland. – Phytotaxa 594: 251–255.
Abstract
"Hieracium lomniczkianum is a new, apomictic species, discovered in the Karkonosze Mountains (Giant Mountains) in the Sudetes, SW Poland. It belongs to the H. wiesbaurianum aggregate which comprises taxa intermediate in characters between H. bifidum s.lat. and H. schmidtii s.lat. The new species is distinguished by a slender stem with small capitula, and by narrow, weakly dentate rosette leaves which are gradually tapered to a winged petiole."

Takano A. & al. 2023: Ploidy level and nuclear DNA content of Taraxacum shikotanense (Asteraceae). – J. Jap. Bot. 98: 19–28.
Abstract
"To estimate the ploidy level frequencies of Taraxacum shikotanense Kitam. (Asteraceae) in Hokkaido, Japan, the nuclear DNA content (2C) of 292 plants from 13 localities was measured by flow cytometry (FCM) using Petroselinum crispum (2C = 4.5 pg) as the internal standard. The chromosome count of the species showed that 11 plants from seven localities were octoploid (2n = 64 = 8x) and five plants from two localities were nonaploid (2n = 72 = 9x). Monoploid genome sizes (1Cx) of the octoploid plants were 1.14–1.22 pg, which were similar to those of the nonaploid plants (1.13–1.17 pg). The expected 2C value of each ploidy level was calculated based on 1Cx = 1.13–1.22 pg, and the frequency of each ploidy level was evaluated. As a result, 183 plants (62.7%) of T. shikotanense examined by FCM were estimated as octoploid. The hexaploid (6x), heptaploid (7x), nonaploid (9x), and decaploid (10x) plants were putatively detected at low frequencies (0.3–4.1%). The monoploid genome size of T. shikotanense was significantly lower than those of the Japanese diploid species (1.41–1.59 pg). This suggests that T. shikotanense arose from an unknown ancestral species with small genome sizes or experienced DNA downsizing as its ploidy level increased."

Kirschner J. & Štěpánek J. 2023: A taxonomic revision of Taraxacum sect. Dissecta, a continental steppe group common in Siberia and adjacent regions of Central Asia. – Phytotaxa 590: 1–67.
Abstract
"Steppe and similar habitats in southern Siberia, Mongolia and adjacent regions harbour a considerable diversity of Taraxacum sect. Dissecta (Asteraceae, Crepidinae); its taxonomic revision is presented. A thorough study of live and herbarium plants revealed 30 species that belong, or are very close, to T. sect. Dissecta; seven species were known previously and 23 are described as new, mostly from the Altai Republic, Novosibirsk, Irkutsk, Lake Baikal and Bratsk. Their distribution includes the Asiatic part of Russia, Kazakhstan, Kyrgyzstan, Mongolia and Xinjiang, China. The name T. dissectum (Ledeb.) Ledeb. is relegated to the synonymy of T. pubescens (Fr.) Fr. A detailed analysis of the original material of the name T. collinum revealed that it consists of mostly juvenile plants belonging to several species of T. sect. Dissecta, and that it requires further study on newly collected material. The frequently reported occurrence of T. sect. Dissecta (as T. dissectum) in the European mountain ranges was reassessed. The reports from the Pyrenees belong to T. pyrenaicum and related species of T. sect. Obliqua. Two mutually similar species, often referred to as T. dissectum, recognized as T. aquilonare Hand.-Mazz. and T. zermattense Dahlst., were studied in order to reconsider the hypothesis that they represent T. sect. Dissecta in the Alps. On the basis of morphological and phytogeographical data, we present this hypothesis as quite plausible but requiring experimental, phylogeographic evidence; a full treatment of both species is also given. The name T. compactum is typified and the species is excluded from T. sect. Dissecta; it belongs to T. sect. Qaisera."

Ballou S. M., Omand K. A., Karberg J., Bonifacino J. M. & Mandel J. R. 2023: A harried past for a glabrous lettuce: Resurrection of Lactuca sanguinea Bigelow (Cichorieae), the wood lettuce from Nantucket Island, Massachusetts, USA. – Capitulum 2(2): 59–68.
Abstract
"We resurrect from synonymy Lactuca sanguinea based on morphological analysis of herbarium specimens and field obser vations. We report recent populations of Lactuca sanguinea occurring in several locations across Nantucket Island in Massachusetts, USA, and provide the first collections in over fifty years within the state. The species consistently has predominantly dark purple-red stems and leaves and crimson corollas, which together with its glabrous nature sets it apart from Lactuca hirsuta. We designate a lectotype, present an expanded morphological description and taxonomic history for the species and provide line drawings and images."

Štěpánek J. & Kirschner J. 2023: A distinctive group of species allied to Taraxacum danubium (T. sect. Erythrosperma, Compositae‑Crepidinae): a taxonomic revision. – Folia Gebot. 57: 269–301.
Abstract
"Within Taraxacum section Erythrosperma, several relatively distinct species groups are recognized. One of them, characterized by leaves with numerous, usually patent, very narrow lateral segments, frequently with their most distal part dilated, and outer phyllaries patent or arcuate-recurved, often with tips approaching the involucre base, with narrow whitish borders, includes species similar to the Central European Taraxacum danubium. This group comprises nine species, the majority of them (five species) being confined to the Balkan Peninsula. Another diversity centre of the group is the southernmost Ukraine. The most widespread species is T. persicum, extending from Iran and the lower river Volga to Central Europe. A detailed taxonomic revision of the whole group is presented, and descriptions, illustrations and lists of specimens studied are given. Two Balkanic species are newly described, the name T. danubium is lectotypified, another three names are relegated to the synonymy of the accepted names, and an unclear name, T. pineticola, is discussed. The species concept in Taraxacum is briefly expounded."

Abstract
"This study presents the first comparative analysis of the leaf secretory structures across Asteraceae. In this work, the leaf secretory structures of more than 500 species of 35 of the 40 tribes and 11 of the 13 subfamilies of Asteraceae are described and compared to evaluate their diversity at the tribe level and to identify evolutionary patterns. Leaf secretory structures are present in 28 of the 35 analyzed tribes and correspond to canals (recorded in 17 tribes), secretory cavities (1 tribe), hydathodes (19 tribes), laticifers (4 tribes) and glandular trichomes (24 tribes). Canals are mostly associated with vascular bundles and predominate in Asteroideae, while cavities were only present within Tageteae. Hydathodes occur in leaves without divisions and with well-developed teeth. Laticifers were observed only in the tribes of Cichorioideae. Seven glandular trichome morphotypes were differentiated by their cellular composition and shape. These observations together with the available information showed that secretory structures are found in 80% of the Asteraceae tribes. Four of the 40 tribes did not present any type of secretory structure. Our study reveals that almost all of the tribes possess one to three types of secretory structures, and are absent in some early-diverging clades. Character evolution analyses show that glandular trichomes are plesiomorphic in Asteraceae. This study found that secretory structures prevail in late-diverging lineages and were taxonomically informative at different levels. Our comparative study of the secretory structures in Asteraceae is essential for the standardization of its terminology and will provide a frame of reference for future studies."

Ferrer-Gallego P. P. & Talavera M. 2023: Rhagadiolus edulis (Cichorieae, Compositae), a replacement name for Lapsana rhagadiolus L. or a name of a new taxon? – Phytotaxa 589: 91-96.
Abstract
"Rhagadiolus edulis (Cichorieae, Compositae) can be treated either as a replacement name or as the name of a new taxon according to the International Code of Nomenclature for algae, fungi, and plants. Treating it as a replacement name would be nomenclaturally disruptive, whereas treating it as the name of a new taxon, confirmed by an appropriate typification, maintains current usage. Therefore, the nomenclatural type for the name Rhagadiolus edulis is discussed. The name is lectotypified by a specimen preserved in the Gaertner Herbarium at TUB.

Abstract
"Hieracium ciucasense is a new, apomictic species described from the Ciucaş Mountains in the Eastern Carpathians, Romania. It belongs to the H. pietroszense aggregate comprising taxa of presumably hybrid origin between H. alpinum L. and H. bifidum s. lat. The new species is illustrated with photographs of the holotype and living plants; it differs from the other taxa of the H. pietroszense aggregate in the Carpathians in that the leaves are brown-purple spotted. The distribution of the H. pietroszense aggregate in the Carpathians is mapped."

Ferreira M. Z., Hernández I. Á & Menezes de Sequiera M. 2023: Taxonomic and nomenclatural notes on Andryala glandulosa subsp. cheiranthifolia (Cichorieae, Asteraceae) from Madeira Island, Portugal. – Phytotaxa 579: 243–254.
Abstract
"Currently two subspecies of Andryala glandulosa endemic to Madeira (Portugal) are recognized: A. glandulosa subsp. glandulosa and A. glandulosa subsp. cheiranthifolia. A thorough revision of both taxonomical and nomenclatural aspects led us to the conclusion that the subspecific epithet cheiranthifolia was misapplied. Thus, we suggest to synonymize Andryala glandulosa with A. cheiranthifolia and accept A. glandulosa as the correct name for the taxon presently known as A. glandulosa subsp. glandulosa. The taxon currently recognized as A. glandulosa subsp. cheiranthifolia exhibits distinct vegetative and reproductive structures when compared to A. glandulosa subsp. glandulosa and should, therefore, be treated as a separate species, for which the name A. subglabrata is hereby proposed. A detailed description and illustration of A. subglabrata are provided and its lectotype is designated. Diagnostic characters are discussed and compared with those of A. glandulosa."

Soltis D. E., Mavrodiev E. V., Gitzendanner M. A., Alexeev Y. E., Godden G. T. & Soltis P. S. 2022: Tragopogon dubius: Multiple introductions to North America and the formation of the New World tetraploids. – Taxon 71: 1287–1298.
Abstract
"Tragopogon (Asteraceae) is an evolutionary model for the study of whole-genome duplication, with two recently and repeatedly formed allopolyploids, T. mirus and T. miscellus, and many additional polyploid species. Tragopogon mirus and T. miscellus formed in western North America following the introduction of three diploids from Europe: T. dubius, T. porrifolius, and T. pratensis. Of these diploids, T. dubius is a shared parent of both tetraploids and is broadly defined and widely distributed in Eurasia. Because human-mediated intercontinental introductions may lead to hybridization with local species, and associated polyploidization, the introduction history of T. dubius from Europe to North America provides further opportunity to investigate both the extent and consequences of plant introductions. Using ITS sequence data, we show that the morphologically diverse, broadly defined T. dubius comprises a complex of at least 10 different ITS types in its native range, six of which have been introduced from Europe into North America. Significantly, although the two allotetraploid species have each formed multiple times on geographical scales from local to regional, recurrent formation is the result of repeated hybridization involving only one of these ITS subtypes. These results reinforce earlier data suggesting that not all diploid genotypes can form allopolyploids. Several entities traditionally considered part of T. dubius s.l. are now recognized as distinct species (e.g., T. lainzii), and it is likely that other distinct ITS genotypes identified here may also mark unique lineages that ultimately merit recognition as separate species. However, more intensive phylogenetic analyses involving many more samples from across the geographic range of T. dubius are required, as are detailed assessments of taxonomy, morphology, and cytology."

Dudáš M. & Vašut R. J. 2022: Taraxacum sect. Erythrosperma in Slovalia III: Taraxacum parnassicum Dahlst., new localities and notes on its distribution and taxonomy. – Acta Bot. Hung. 64: 273-283.
Abstract
"The paper presents new records of Taraxacum parnassicum, the most common member of Taraxacum section Erythrosperma in Slovakia. The species has been recorded in most of the 31 phytogeographical districts of Slovakia. At least 25 new localities were discovered, and many old ones were confirmed. T. parnassicum prefers natural and semi-ruderal sites on limestone, rarely on volcanic and sandy soils, predominantly not shaded. The majority of populations occur from the lowland to supracolline vegetation belt, mainly at elevations of 140–700 m a.s.l., with the altitudinal maximum at 1,410 m a.s.l. A distribution map is given with the list of localities from the whole territory of Slovakia as well as short discussion about its taxonomy and ploidy level."

Jiménez J. F., Ramírez-Rodríguez R., Melendo-Luque M., Suárez-Santiago V. N. & Sánchez-Gómez P. 2022: Genetic diversity and structure of the narrow endemic species Crepis granatensis: implications for conservation. – Pl. Biosystems 156: 1129-1137.
Abstract
"In this study, we studied the genetic diversity and population genetic structure of the endangered endemic Crepis granatensis, using amplified fragments length polymorphism (AFLP) and plastid DNA (cpDNA). No genetic divergences were obtained using cpDNA markers. Three primers combinations selected from a total of 12 produced a total of 421 fragments, of which 418 (99.3%) were polymorphic. The total genetic diversity of C. granatensis was moderate (Ht = 0.260). Neís gene diversity ranged from 0.202 to 0.258. The fixation index (Fst) was 0.137, suggesting low to moderate genetic differentiation among populations. The AMOVA analysis revealed that genetic diversity was mainly concentrated among individuals within populations (74%), while 8% was found among populations and 18% among regions. The Bayesian analysis and PCoA identified two genetic clusters: one corresponded to La Sagra population and the other corresponded to the Mágina populations. Based on our genetic results, it is necessary to preserve the evolutionary potential of C. granatensis by protecting all extant populations. Both in situ and ex-situ conservation measures should be considered. Reinforcement, reintroduction, and translocation programmes could be performed if necessary. Finally, such conservation strategies should be considered both in the current recovery plan and management actions for the species."

Kuluev B., Fateryga A., Zakharova E., Zakharov V. & Chemeris A. 2022: Pinkish-achened form of Taraxacum hybernum Steven – a source of inulin and high molar mass natural rubber. – Botany Letters, https://doi.org/10.1080/23818107.2022.2147998
Abstract
"Taraxacum hybernum Steven (Asteraceae family) native to Southeast Europe is a promising rubber-bearing dandelion species. In the 1930s, several phenotypically distinct forms were described in this dandelion, such as brown-achened and pinkish-achened. More than 70 years after termination of research of temperate zone rubber-bearing plants we were able to find both forms of this species of dandelion in natural habitat. The species is still poorly studied, and there is no information about the differences in the quality and quantity of rubber between brown-achened and pinkish-achened forms. Therefore, the purpose of our study was to analyze the root morphology and yield, the rubber and inulin content, and to determine the molar mass of rubber in brown-achened and pinkish-achened T. hybernum. These two forms of T. hybernum, as well as T. kok-saghyz Rodin and T. brevicorniculatum Korol., were studied. The results show that the root shape most attractive for domestication is typical of brown-achened T. hybernum. The greatest mass of roots was gained for pinkish-achened T. hybernum. The rubber content was about 6% in T. kok-saghyz, 3% in both forms of T. hybernum, and 1.5% in T. brevicorniculatum per dry root mass. Taraxacum kok-saghyz and pinkish-achened T. hybernum turned out to be the leaders in inulin content. Of all four dandelions, the molar mass of rubber was more than 1 million g/mol only for T. kok-saghyz and pinkish-achened T. hybernum. Pinkish-achened T. hybernum is a good alternative for T. kok-saghyz and can be recommended for domestication and cultivation in the temperate zone."

Vladimirov V. & Stoyanov S. 2022: A new species record of Tragopogon (Asteraceae) for the Bulgarian flora. – Phytol. Balcan. 28: 341-346.
Abstract
"Tragopogon coelesyriacus (Asteraceae) is reported for the first time for the Bulgarian flora. It has been recorded in several closely situated localities in the Eastern Rhodopi Mountains, all on the territory of Ivaylovgrad Municipality. The species is easily recognized by the other non-yellow flowering Tragopogon species in the Bulgarian flora by its very short ligules and long-beaked, buff-coloured to nearly whitish achenes. Brief morphological description of the taxon and a key for determination of the non-yellow flowering species in Bulgaria are provided. Chromosome number of 2n = 2x = 12 is reported. The genome size of the species is in the range 1C = 2.21 – 2.24 pg. Data about the distribution, habitats and populations of the species in the Bulgarian flora is provided. The text is amply illustrated."

Beharav A. 2022: Lactuca georgica Grossh. is a wild species belonging to the secondary lettuce gene pool: additional evidence, obtained by KASP genotyping. – Genet. Resources Crop Evol. https://doi.org/10.1007/s10722-022-01502-7.
Abstract
"This work evaluated the genetic relationships among 442 single-seed descent accessions, representing eight Lactuca spp., including five wild Lactuca relatives (WLRs) (Lactuca georgica, L. altaica, L. saligna, L. serriola, L. aculeata), L. tuberosa, L. undulata, and the domesticated lettuce, L. sativa, 437 of them representing a core subset of the Institute of Evolution's Wild Lettuce Gene Bank (IoE's WLGB) collection. The analysis was performed by profiling 115 single-nucleotide polymorphism markers with the fluorescent KASP genotyping assay. KASP marker fragments were scored as either allele “A” or allele “B”, and then treated as bi-allelic data, but the dataset also included a relatively high number of U-scores, noting the absence of the specific sequence, that were treated as missing data. Often U-scores were specific for a certain species. Data analysis of the five WLRs showed that allele frequencies of 103 (97.2%) out of 106 differentiating loci varied significantly among the species, where 59.7% of the KASP marker diversity was between species. A neighbor-network analysis involving samples of the five WLRs and a single L. sativa cv. clearly clustered all 430 samples in accordance with their taxonomic determination. These results obtained from multiple complementary analyses of large natural populations and individuals, question the assignment of L. georgica to the primary lettuce gene pool. Together with our previous results obtained by using TRAP markers and hybridization experiments, we conclude that L. georgica is a constituent of the secondary lettuce gene pool. Our analyses shed also light on the proper placement of L. altaica."

Abstract
"Distribution pattern and ecological preference for habitat including altitude and soil of Lactuca L. (s. str.) and allied genera viz. Steptorrhamphus, Cephalorhynchus and Melanoseris have been studied in Pakistan and Kashmir. All the taxa belonging to these genera are mostly confined to high mountain ranges in Pakistan and Kashmir. Out of 33 taxa, two taxa belonging to Lactuca are subcosmopolitan. The seven taxa are Irano Turanian (Central Asian) elements of which 2 belong to Lactuca and 2 to Steptorrhamphus and 3 belong to Cephalorhynchus. There are 8 Sino Japanese elements of which one belongs to Lactuca and 7 belong to Melanoseris. However, 3 more taxa viz. M. rapunculoides, M. decipiens var. decipiens and M. decipiens var. multifida are also tentatively recognized as Sino Japanese elements. Beside these 4 taxa are biregional, of which 3 Lactuca species are Mediterranean Irano Turanian elements whereas L. tatarica is an Irano-Turanian Euro Siberian element. There are 13 taxa which are endemic to subendemic, most of these are endemic to Pakistan (Western Himalayas and mostly known from type locality). However, M. gilgitensis seems to be confined to Karakorum Mountains and 2 species viz. M. alii and M. astorensis occur in Western Himalayas and Karakorum. It is difficult to classify these taxa into definite phytogeographical elements until more information is available."

Abstract
"In this study, the morphology, global threat level and taxonomic status of the halophytic endemic Scorzonera hieraciifolia (Asteraceae) was investigated of new data. Detailed examinations on newly collected samples from the natural areas of the species and the specimens kept in national/international herbaria indicated that S. hieraciifolia is characterized by crisped hairs at the stem base; simple (lanceolate, ovate or elliptical) or compound (pinnate with deeply linear segments) leaves, ovate and corniculate outer phyllaries; glabrous or lanate, 4-6 mm length, verrucose and stipitate achenes. The populations of the species currently detected in salt marsh and steppe areas (10 different areas) are appraised strong, however considering that it could be affected by changes that may occur in saline areas due to global climate changes. It has evaluated in near threatened (NT) category in a global scale. The distribution areas of the species were revealed by evaluating both the literature and current data obtained within the scope of the project supported by TUBITAK. Finally, the taxonomic status of S. hieraciifolia has been clarified by comparing with close (relative) species in terms of morphology and chorology."

Hatami, E., Khajoei Nasab F. & Safavi S. R. 2022: Conservation priorities and distribution patterns of the genus Pseudopodospermum in Iran. – Iran. J. Bot. 28: 128-138.
Abstract
"The present study provides an overview of geographic distribution patterns as well as the conservation priorities assessment of the genus Pseudopodospermum in Iran, using a GIS framework. A set of geographic distribution data was compiled through field studies, reviews of Flora Iranica, Flora of Iran, and examination of the herbarium specimens deposited at various herbaria. The geographic distribution mappings of the genus were analyzed using ArcView and DIVA-GIS software. High species richness was observed in Kurdo-Zagrosian Province, followed by Fars-Kerman, Atropatanean, and Northern Khorasan Provinces in Irano-Turanian phytogeographical region. Regarding our results, it could be concluded that effective conservation management in Kurdo-Zagrosian Province would lead to protecting a high percentage of Pseudopodospermum species against the threat of extinction."

Gottschlich G. 2022: Die Hieracium-Kollektion im Herbarium Tubingense (TUB) – Ergebnisse einer Revision. – Jahreshefte Ges. Naturk. Württemberg 178: 5–31.
Abstract
"The collection of the genus Hieracium (Compositae) of the herbarium of the University of Tuebingen (TUB) with its 3.195 specimens is revised. The collection is valuable because it includes the collections of Josef Alois Froelich, an early monographer of the genus, the herbarium Hochstetter with many specimens collected by the “Botanischer Reiseverein Esslingen” (an association for the purpose of collecting and distributing herbarium specimens), and the herbarium of the monastery of Beuron (ERZ). The collection includes 183 species, 299 subspecies, including 157 type specimens, however many of them only for names of taxa of now irrelevant taxonomic ranks. One new combination (upgrade) is made (Hieracium bifidum subsp. trinitatimontis (Zahn) Gottschl.)."
