Crawford D. J., Kelly J. K. & Anderson G. J. 2024: Reproductive biology of Asteraceae on oceanic islands. – Bot. Rev. 90: 67–108.

Abstract
"Asteraceae are among the most abundant angiosperm families on oceanic islands. The reproductive biology of Asteraceae is reviewed and the attributes of the family contributing to their success on islands are discussed. Asteraceae are effective dispersers (the small, single-seeded fruits are moved great distances by wind and birds), and colonization is most likely limited by establishment. The pollinators of the colonizing ancestors rarely disperse with them to islands. Divorced from the pollinators of their ancestral habitats, the capitulum of aggregated small, shallow flowers typical of Asteraceae facilitates pollination of colonizers by various novel biotic visitors and by wind. Self-compatible (SC) colonizing ancestors are common, permitting establishment of sexual populations from one or few propagules. However, several large insular lineages of Asteraceae originated from functionally self-incompatible (SI) colonizers that may have also possessed the capacity to set some self-seed. Establishment may also be facilitated by dominance relationships among S-alleles in the sporophytic SI (SSI) system of Asteraceae, increasing cross-compatibility within small populations. Factors potentially promoting outcrossing in SC Asteraceae are: gynomonoecy, with temporal separation of receptive pistillate ray florets and pollen presentation in the hermaphroditic disc florets of a capitulum (interfloral protogyny); and intrafloral protandry where pollen presentation occurs before stigmata become receptive. Dioecy, gynodioecy, and monoecy are infrequent sexual systems in insular Asteraceae. Multiple paternity is similar in island composites to other Asteraceae, suggesting that neither compatible mates nor pollinators are typically limiting. Additional studies, particularly with genomic markers, are needed for more refined insights into mating systems and paternity in island Asteraceae as these results have important conservation implications."

Efimov P. G. 2023: Taraxacum erythroboreale (Asteraceae), a new species of presumably intersectional hybrid nature with broad distribution in North European Russia (Taraxacum Notulae Rossiae Boreali Europeae II). – Novosti Sist. Vyssh. Rast. 54(e12): 1–11.

Abstract
"Taraxacum erythroboreale Efimov, a new apomictic species, is described and illustrated. It occurs in Russia (North of the European part), in the Murmansk and Vologda regions, in the Komi Republic, being locally very abundant. It occupies mainly dry sandy roadsides and other similar ruderal places, and seems benefiting from the anthropogenic disturbance of the land. The new species may belong either to the section Erythrosperma (H. Lindb.) Dahlst., or have originated from the hybridization between this section and some species of an Asiatic section like Stenoloba Kirschner et Štěpánek or Dissecta (Soest) R. Doll. The new species displays rather wide morphological polymorphism as to the presence/absence of purplish achene pigmentation, shape of outer phyllaries, corniculation of phyllaries, and in some other traits."

Xu L.-S., Song Z.-Q., Liao S.-Y. & Chen Y.-S. 2024: Qineryangia, a new genus from the Hengduan Mountains and new insights into the phylogeny of the subtribe Crepidinae (Cichorieae, Asteraceae). –  J. Syst. Evol.
https://doi.org/10.1111/jse.13066.

Abstract
"The Crepidinae are the largest subtribe of the Cichorieae (Asteraceae). Debate remains over the circumscription and phylogeny of this subtribe, mainly due to its complex morphology and the poor phylogenetic signal provided by traditional Sanger sequencing markers. In this study, a well-resolved phylogeny of the subtribe Crepidinae, consisting of seven highly supported clades, was obtained for the first time using nuclear data with a phylogenomics approach (Hyb-Seq). Using this phylogeny along with other evidence, we propose a new taxonomic framework for the Crepidinae with seven lines and 29 genera, which merges subtribe Chondrillinae with the Crepidinae. We also describe a new monotypic genus, Qineryangia, that is characterized by broad involucres, loose imbricate phyllaries with wavy margins, and thick pappus bristles."

Gültepe M., Makbul S., Güzel M. E., Türker Z. & Coşkunçelebi K. 2024: Tragopogon davutii-turanii: a new species of Tragopogon from Anatolia. – Nordic J. Bot. 2024: e04178.

Abstract
"A new salsify species, Tragopogon davutii-turanii, is described from Anatolia based on micro-/macro-morphological and molecular evidence. The new species is morphologically similar to T. vvedenskyi and T. abbreviatus, but differs from T. vvedenskyi mainly in ligule colour and from T. abbreviatus by achene characters and number of phyllaries. In contrast to morphological similarities, based on the phylogenetic tree obtained from nrDNA ITS sequences T. davutii-turanii is closely related to T. stenophyllus and T. coelesyriacus. Diagnostic characters, description, and conservation status of the new species, as well as micro- and macro-morphological features of its achenes and pollen grains, are provided."

Abstract
"In this paper, we describe a new species, Melanoseris penghuana, from Mt. Jiaozi Xueshan located in North-central Yunnan, China. Despite its morphological similarities to M. likiangensis, M. penghuana exhibits distinct differences in leaf texture, shape of terminal lobes, indumentum of leaves, peduncles, and involucres, as well as the length of the achenes. Additionally, the conservation status of this species is classified as Vulnerable through data analysis from two field surveys."

Uhlemann I. & Thiele K. 2024: On artificial F1-hybrids and backcrosses between Taraxacum koksaghyz and species of Taraxacum sect. Taraxacum (T. officinale s. l.) and their invasive potential. – Schlechtendalia 41: 1–16.

Abstract
"Taraxacum koksaghyz, a rubber producing plant grown in temperate regions, is used together with diploid Taraxacum linearisquameum (sexual T. officinale s. l.) or triploid species of T. sect. Taraxacum (agamospermous (micro-)species of T. officinale s. l.) as parental plants to get artificial rubber producing hybrids. T. koksaghyz × T. oblongatum and T. ‘Hybrid 207’ are extremely rare triploid offspring examples for 2×/3× combinations. The invasive potential of T. ‘Hybrid 207’ seems to be low, but interspecific competition with weeds is stronger than in T. koksaghyz which completely failed to compete against weeds. Artificial hybrids from 2×/2× combinations (T. koksaghyz × T. linearisquameum and reciprocal and backcrosses with parents) are diploid, generally have a morphological intermediate appearance between parents and partially produce rubber (0.1–3.7%). The fertility of achenes of offsprings depends on the parental function (pollen recipient or pollen donor). In case of T. linearisquameum as pollen recipient, fertility will be high (85–97%) and in case of T. koksaghyz as pollen recipient, fertility is low (1.5–9%)."

Štěpánek J., Kirschner J. & Uhlemann I. 2023: A survey of the oreophytic species of Taraxacum in the Carpathians reveals a very limited overlap with the flora of the Alps. – Preslia 95: 475–591.

Abstract
"The genus Taraxacum in the subalpine and alpine areas in the Carpathians (Poland, Slovakia, Ukraine, Romania, montane habitats in Czechia) is revised using newly collected material and old herbarium collections. Four Taraxacum sections are recognized, viz. T. sect. Crocea (= T. sect. Fontana), T. sect. Alpina, T. sect. Rhodocarpa (= T. sect. Alpestria) and a newly described T. sect. Oreodoxa Štěpánek et Kirschner, a peculiar monotypic taxon with a single species, T. incredibile, confined to limestone ranges in northern Romania. There are 16 species in Slovakia, 7 in Poland, 5 in Ukraine and 11 in Romania; out of the 25 species adopted after the revision, 10 are newly described and 14 occur only in a single country. The study of the Taraxacum venustum group in the Carpathians revealed a new Romanian species, which is described, and another new species in the Western Alps, which in the present paper is compared with the similar Bulgarian species, T. humifusum of T. sect. Bulgarica. Taraxacum venustum sensu lato is reported from the Eastern Carpathians, but further study is needed. Three species known from the Carpathians, T. crocelliforme, T. pawlowskii and T. hercynicum, are also recorded in the Alps. Endemism of dandelions in the Carpathians is analysed and compared with published data for other Carpathian plants and the neighbouring regions. Twenty-one species (of 25) are confined to the Carpathians, 17 are endemic to a single Carpathian region and most of them to the Western Carpathians. The main literature sources of Taraxacum records from the Carpathians are analysed in detail; numerous published records of Alpine species in the Carpathians were rejected. The seven names published by R. Doll from Slovakia were thoroughly revised, with four names accepted and three synonymized. Five names are lectotypified."

Rastegar A., Ghaderi H., Maroofi H., Advay M., Jalili A. & Jamzad Z. 2023: The conservation status of Scorzonera nivalis, an endemic species of Iran. – J. Iran Nature 8(4): 135–140.

Abstract
"Scorzonera nivalis Boiss. & Hausskn. (Asteraceae) is one of the narrowest endemic species in Iran's flora, restricted to the Schahu and Avroman Mountains. IUCN criteria and GeoCAT data (EOO= 339.736 km2; AOO= 4.41 km2) classify this species as Critically Endangered (CR). This species was not collected after it was introduced 156 years ago by Boissier and Haussknecht until 2013 when it was collected for the second time from Schahu Mountain. Later studies conducted in Kurdistan Province added other populations from the Avroaman Mountains to the samples of this valuable species. The most efficient way to protect this species is to help its propagation through seeding and sowing in other similar habitats in the Schahu and Avroman Mountains. Introducing Schahu Mountain as a protected area by the Department of Environment of Iran, preventing livestock from entering the top of the mountain, collecting seeds, and storing them in the Natural Resources Gene Bank of Iran are other effective ways to protect this valuable reserve."

Safavi S. R., Rad M. A., Jamzad Z. & Jalili A. 2023: The conservation status of Scorzonera alborzensis Safavi & Amini Rad, an endemic species from Iran. – J. Iran Nature 8(3): 107–112.

Abstract
"Scorzonera alborzensis is one of the exclusive and rare species collected and reported from only one place in the country (Mazandaran province: between Baladeh and Nour, Siahsang mountains, 3023 m). The genus Scorzonera L. belongs to the Asteraceae family and has 19 endemic species in Iran. Based on the guidelines of the International Union for Conservation of Nature (IUCN), Area of Occupancy (AOO), Extent of Occurrence (EOO), habitat quality, population size, and natural reproduction of the species were evaluated. According to the field studies, the area of occupancy (AOO) and extent of occurrence (EOO) were estimated at an area of 0.01 km2 (only one locality), and the number of adult individuals is between 15 and 20, with a very low regeneration rate. Therefore, according to our studies, Scorzonera alborzensis is defined as a Critically Endangered (CR) species. Road construction and grazing in this species' habitat are among the life-threatening factors. As a result, the Natural Resources and Watershed Organization needs to protect this species' habitat. Further, ex-situ conservation must be achieved by preserving seeds in the Natural Resources Seed Bank, growing seeds, and cultivating seedlings in Iran's National Botanical Garden."

Safavi S. R. & Rad M. A. 2021: The conservation status of Scorzonera persica Boiss. & Buhse, an endemic species from Iran. – J. Iran Nature 6(5): 117–123.

Abstract
"The Scorzonera L. (Asteraceae) has 18 endemic species in Iran. S. persica Boiss. & Buhse is one of the endemic species and has only been collected and reported from three localities in the country. Based on the IUCN guidelines, different categories and criteria were used to evaluate the status of the species as follows: Area of Occupancy (AOO), Extent of Occurrence (EOO), quality of habitat, size of the population, and regeneration. According to the field studies, S. persica occupies an area of 0.6 km2. In the analysis of GeoCAT software, the extent of occurrence was 2720 Km2. Based on our results, the conservation status of S. persica is defined as Critically Endangered (CR). Construction operations and grazing in the habitat of this species are among the life-threatening factors of this species, so it seems necessary to protect this species by protecting its habitat."

Abstract
"A pentaploid taxon from the Pilosella macranthela group was discovered in Lower Franconia/Bavaria which is newly described here as P. macranthela subsp. sylvae-pici. It grows mainly in the Bavarian Bunter Spessart and occurs with three small, isolated stands also in the limestone area of the Main valley and Tauber area. Its habit of growth is intermediate between the furcata and laxicephala types of Pilosellae with epigeal and partly hypogeal stolons and a tendency to form clusters. The upper and lower surfaces of the rosette leaves have stellate hairs. The peduncles and the phyllaries are densely covered with dark glandular hairs with yellowish glandular heads. The lateral teeth of the ligules often are separated by incisions. A tetra- und pentaploid transitional taxon between P. macranthela subsp. sylvae-pici and P. officinarum is described as P. ottonis. P. ottonis is tetra- and pentaploid with up to 7 capitula. It is densely covered with dark stalk glands on phyllaries and resembles forms of P. acutifolia in habit. The phyllaries of P. ottonis are covered with numerous epidermal papillae with adiameter of about 10–20 μm and in this aspect resemble P. macranthela subsp. sylvae-pici and P. glomerata. However, in P. officinarum epidermal papillae are absent. Plants of genetically heterogeneous tetra- and heptaploid P. macranthela have been found outside the Spessart as spontaneous hybrids between P. glomerata and P. officinarum and also occur sporadically without P. glomerata in the vicinity."

Abstract
"Taraxacum sect. Crocea (the correct name for the taxon formerly called T. sect. Fontana) comprises putative glacial relicts restricted to the European Alps, possibly the Carpathians (not recorded yet), and south-eastern European mountains. In this paper, six species of this section are recognised in the Alps: T. absurdumT. fontanosquameumT. fontanumT. insubricumT. jacobianum spec. nova and T. pseudoboreigenum. Four names are relegated to synonymy: T. cochleatophyllumT. fontanicolaT. graiense and T. pseudofontanum. Further names formerly associated with T. sect. Crocea in the Alps are excluded, synonymisised with species from other sections or treated as nomina dubia or species incertae sedis: T. aestivumT. aurantellumT. binilobatumT. corsicumT. croceicarpumT. crocellumT. fontaniformeT. magnopyramidophorumT. malyiT. obovatifoliumT. peralatumT. pohliiT. pomposumT. renosenseT. rufocarpumT. senile and T. silvicola. For each Alpidic T. sect. Crocea-species, a type is designated (where still necessary) and a detailed description, a comparison with relatives, a list of specimens studied by the author, information on distribution and ecology, and drawings and photographs of relevant characters are given. A determination key for all species of the section in the area under study is provided."
