Not all members of the International Cichorieae Network do have access to botanical libraries. As a service we would like to point to recent publications regarding Cichorieae. However, some articles will escape our attention. Therefore, your hints to recent publications are always welcome.

Marciniuk J., Marciniuk P. & Musiał K. 2018: Taraxacum mariae, a new species of T. section Palustria (Asteraceae) from Poland. – Phytotaxa 376: 207–213.

Abstract:
Taraxacum mariae J. Marciniuk & P. Marciniuk is a new triploid species of T. sect. Palustria. In terms of morphology it is closest to the group of T. brandenburgicum and T. bibulum. In the presented paper, the description of the new species, its distribution, diagnostic characters and habitat requirements are provided.”

Beharav A., Khalifa S. & Nevo E. 2018: New insights into the range, morphology, and natural hybridization of wild Lactuca aculeata in Israel. – Israel J. Pl. Sci. 65: http://dx.doi.org/10.1163/22238980-00001045

Abstract:
“In recent years we initiated extensive studies on the characterization of the population structure of wild Lactuca relatives (WLRs) originating from their center of origin and diversity in Southwest Asia. The objectives of our research program are related to the identification, collection, distribution, conservation and sustainable use of these unique plant genetic resources (PGR) for breeding. Natural populations of Lactuca aculeata Boiss., a wild lettuce, closely related and fully inter-fertile with cultivated lettuce, L. sativa L., were identified throughout northeastern Israel. The collection includes 485 seed samples, which is likely the largest and most diverse collection of this important WLR. Seeds were collected from 46 locations, representing its ecogeographic distribution in northeastern Israel. Together with 14 additional observed localities, we recorded our observations from a total of 60 native locations of L. aculeata. Thus, we assume that northeastern Israel is an ecological domain where natural L. aculeata populations can be found. The analyzed data allowed us to specify the borders of the growing area in the region, as well as to describe the ecological features of the habitats and altitude distribution of natural L. aculeata within the studied area. Notably, our data included new findings of native locations of L. aculeata on the western side of the watershed in Israel. Selected morphological characteristics, from the regeneration of 185 samples, verified the identity of all except one as L. aculeata. Some progenies (0.27%) of the original collected plants were identified as hybrids of L. aculeata x L. serriola.”

Jemelková M., Kitner M., Křístková E., Doležalová I. & Lebeda A. 2018: Genetic variability and distance between Lactuca serriola L. populations from Sweden and Slovenia assessed by SSR and AFLP markers. – Acta Bot. Croat. 77: 172–180.

Abstract:
“The study involved 121 samples of the common weed, Lactuca serriola L. (prickly lettuce), representing 53 populations from Sweden and Slovenia. The seed materials, originating from different habitats, were regenerated and taxonomically validated at the Department of Botany, Palacký University in Olomouc, Czech Republic. The morphological characterizations of the collected plant materials classified all 121 samples as L. serriola f. serriola; one sample was heterogeneous, and also present was L. serriola f. integrifolia. Differences in the amount and distribution of the genetic variations between the two regions were analyzed using 257 amplified fragment length polymorphism (AFLP) and 7 microsatellite (SSRs) markers. Bayesian clustering and Neighbor-Network were used for visualization of the differences among the samples by country. Under the Bayesian approach, the best partitioning (according to the most frequent signals) was resolved into three groups. While the absence of an admixture or low admixture was detected in the Slovenian samples, and the majority of the Swedish samples, a significant admixture was detected in the profiles of five Swedish samples collected near Malmö, which bore unique morphological features of their rosette leaves. The Neighbor-Network analysis divided the samples into 6 groups, each consisting of samples coming from a particular country. Reflection of morphology and eco-geographical conditions in genetic variation are also discussed.”

Abstract:
Gundelia purpurascens (Bornm.) Fırat comb. & stat. nov. is proposed. Diagnostic and morphological characteristics, as well as full descriptions and the detailed photographs are provided. This taxon occurs in (Seqlawa) north Iraq and Şırnak (east Anatolia).”

Kim S.-H., Mejías J. A. & Kim S.-C. 2019: Next generation sequencing reveals the complete plastome sequence of newly discovered cliff-dwelling Sonchus boulosii (Asteraceae: Cichorieae) in Morocco. – Mitochondrial DNA Part B 4(1): 164-165.

Abstract:
The complete chloroplast genome sequences of newly discovered cliff-dwelling species of Sonchus, S. boulosii, were reported in this study. The S. boulosii plastome was 152,016 bp long, with the large single copy (LSC) region of 83,988 bp, the small single copy (SSC) region of 18,566 bp, and two inverted repeat (IR) regions of 24,731 bp. The plastome contained 130 genes, including 88 protein-coding, six ribosomal RNA, and 36 transfer RNA genes. The overall GC content was 31.2%. Phylogenetic analysis of 12 representative plastomes within the order Cichorieae suggests that S. boulosii is closely related to S. oleraceus.

Wolanin M. M. & Musiał K. 2918: Chorology and taxonomic issues of Taraxacum danubium and Taraxacum tortilobum (section Erythrosperma), new species to the Polish flora. – Wulfenia 25: 17–24.

Abstract:
“In the past 20 years, the interest in Taraxacum has considerably increased among Polish botanists, however, with the exception of marsh dandelions (Taraxacum section Palustria), the taxonomy and chorology of this group are still poorly examined. In 2012, comprehensive taxonomic-chorological studies on Taraxacum sect. Erythrosperma were launched in Poland. T. danubium and T. tortilobum, species previously unknown in Poland, were identified during this research. We found that these rare dandelion species occur in Poland regionally. Karyological analysis showed the triploid chromosome number (2n = 3x = 24) in both taxa. Current research results also suggest that the previously mentioned diploid T. erythropermum does not occur in Poland.”
