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.

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."

Abid R. & Qaiser M. 2023: Distribution pattern and ecology of Lactuca L. and its allied genera (Lactucineae –Cichorieae) in Pakistan and Kashmir. – Pakistan J. Bot. 55: 159-169.

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."

Makbul S. , Coşkunçelebi K. & Güven S. 2022: Güncel veriler ışığında Scorzonera hieraciifolia (Asteraceae)’nın taksonomik durumunun değerlendirilmesi. – Bağbahçe Bilim Dergisi 9: 21-28.

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.)."
