Qiu J., Zhang J.-W., Gao T.-G. & Tan D.-Y. 2020: Crepis desertorum (Asteraceae, Cichorieae), a new species from northern Xinjiang (China) based on morphological and molecular data. – Pl. Diversity  42: 74–82.

Abstract
Crepis desertorum from the Junggar Basin of northern Xinjiang, northwestern China, is described as a new species. Molecular studies indicate that the species is closely related to Crepis frigida. Morphological studies indicate that it is similar to Crepis sancta subsp. bifida but differs from the latter taxon in having glandular hairs on the stem, a flat receptacle and dimorphic achenes. Chromosome features and pollen and achene ultrastructure also are described for the new species."

Coşkunçelebı K., Gültepe M., Güzel M. E. & Makbul S. 2020: Tragopogon abbreviatus (Asteraceae): a little-known species inferred from morphological and molecular analysis. – Turk. J. Bot. 44: 269-280.

Abstract
Tragopogon  porrifolius  occurs  in  Turkey  with  3  taxonomically  confused  subspecies:   T.  porrifolius  subsp.  eriospermusT.  porrifolius subsp.  longirostris, and  T.  porrifolius  subsp.  abbreviatus.  In  the  present  paper,  T.  porrifolius  subsp.  abbreviatus endemic  to  Turkey  is  raised  at  specific  level  based  on  morphological  and  molecular  analysis.  After  detailed  assessment  of  original  herbarium  specimens and literature studies, we found that this name is not typified yet. Thus, a lectotype is provided together with an emended diagnosis; synonym, distribution map, and conservation status for the first time. Additionally, a preliminary phylogenetic position of this little-known taxon is given on several newly sequenced data.”

Gottschlich G. 2020: Anmerkungen zur Nomenklatur von Hieracium kalksburgense Wiesb. und Wiedereinsetzung des Namens Hieracium canum Peter. – Kochia 13: 17–21.

Abstract
“The type material of Hieracium kalksburgense is heterogeneous and does not fit with the taxonomical amplitude hitherto ascribed to this intermediate species. According to the intention of Wíesbaur as author the name H. kalksburgense is lectotypífied with a specimen, belonging to H. acutifolium, and thereby synonymized. As a  consequence, the name H. canum Peter is re-established for the intermediate species „cymosum < pilosella" and lectotypífied. As there exists no valid name in the alternative genus concept under Pilosella, a new combination is provided.”

Bartolucci F., Galasso G. & Conti F. 2020: Nomenclatural novelties and typification of names in Scorzonera sensu lato (Asteraceae, Cichorieae) for the Italian vascular flora. – Phytotaxa 437: 279-290.

Abstract
“According to recent molecular study, the genus Scorzonera sensu lato is polyphyletic. A revised circumscription of this genus was proposed with the recognition of seven genera: Scorzonera sensu stricto, Gelasia, Lipschitzia, Pseudopodospermum, Pterachaenia, Ramaliella, and Takhtajaniantha. Accordingly, a taxonomic treatment of the genus Scorzonera sensu lato for the Italian vascular flora is presented. Nomenclatural types for six names are designated here: Scorzonera calcitrapifolia var. decumbens, S. columnae, S. deliciosa, S. neapolitana, S. trachysperma var. undulata, and S. villosa. Furthermore, the following new combinations are proposed: Gelasia villosa subsp. columnae, Pseudopodospermum hispanicum subsp. asphodeloides, P. hispanicum subsp. neapolitanum, and P. undulatum subsp. deliciosum.”

Wang Z.-H., Kilian N., Chen Y.-P. & Peng H. 2020: Sinoseris (Crepidinae, Cichorieae, Asteraceae), a new genus of three species endemic to China, one of them new to science. – Willdenowia 50: 91–110.

Abstract
“Studies to elucidate the systematic position of two Chinese species described originally as Lactuca hirsuta and L. scandens, of which only historical specimens from the late 19th and early 20th centuries were known, revealed the occurrence of three different species. Molecular phylogenetic analysis of these species based on sequences of the nuclear ribosomal internal transcribed spacer (nrITS) region and three plastid DNA markers (trnL-F, psbA-trnH, matK) uncovered a hitherto unknown lineage in a first comprehensive phylogenetic backbone of the subtribe Crepidinae (Asteraceae, tribe Cichorieae). Substantiated by comparative morphological studies, this lineage is described as a new genus, named Sinoseris, endemic to the Chinese provinces Sichuan and Yunnan. One of its three species is new to science, while another is conspecific with both L. hirsuta and L. scandens. The third was meanwhile described by other authors as Nabalus muliensis and is now transferred to Sinoseris.”

Hatami E., Mirtadzadini M., Bordbar F. & Jones K. E. 2020: Delimitation of Iranian species of Scorzonera subg. Podospermum and S. subg. Pseudopodospermum (Asteraceae, Cichorieae) based on morphological and molecular data. – Willdenowia 50: 39–63.

Abstract
Scorzonera L. is represented by 57 species in Iran including three subgenera: S. subg. Scorzonera, S. subg. Podospermum and S. subg. Pseudopodospermum. Species of S. subg. Podospermum and S. subg. Pseudopodospermum in Iran are morphologically similar, which limits species delimitation. In order to clarify intersubgeneric and interspecific delimitation in Iran, we carried out extensive sampling of the two subgenera in Iran. We conducted phylogenetic analyses based on the nuclear Internal Transcribed Spacer (nrITS), detailed morphological studies, and we evaluated the systematic value of achene features. Our results showed that Scorzonera s.l. is polyphyletic, and both S. subg. Podospermum and S. subg. Pseudopodospermum are monophyletic. The monophyly of S. subg. Podospermum morphologically corresponds to a combination of characters containing pinnatifid leaves, phyllaries with black corniculate projections, and the presence of a swollen carpopodium on the achenes. A comparison of the topology observed in the nrITS phylogeny with achene features indicates that a sculptured achene wall surface in members of S. subg. Pseudopodospermum provides a synapomorphy for this lineage. This study supports a broader circumscription of S. subg. Pseudopodospermum with the addition of S. calyculata (S. sect. Incisae), S. ovata, S. papposa and S. paradoxa (S. sect. Papposae). Finally, we provide a taxonomic treatment, including an identification key and species diagnoses and distributions, with nomenclature of Iranian species.”

Gottschlich G. 2020: Synopse der für Deutschland nachgewiesenen Arten und Unterarten der Gattung Hieracium s.l. (Hieracium s. str. und Pilosella), aufgeschlüsselt nach Vorkommen in den einzelnen Bundesländern / Synopsis of all species and subspecies of the genus Hieracium s. l. (Hieracium s. str. and Pilosella) in Germany according to the records cited in literature for the German federal states. – Forum Geobot. 9: 1–59.

Abstract
“A list of 205 collective species and 1563 subspecies of the genus Hieracium s. l. detected for Germany and its federal states, is provided. As the most infraspecific taxa were described under Hieracium s.l. and to avoid too much invalid names under Pilosella in the list, a separation of Hieracium and Pilosella is remained undone. By coloured marking additional informations are given whether a subspecies is originally described from a German federal state or its name has a syntype from Germany”

Zaika M. A., Kilian N., Jones K., Krinitsina A. A., Nilova M. V., Speranskaya A. S. & Sukhorukov A. P. 2020: Scorzonera sensu lato (Asteraceae, Cichorieae) – taxonomic reassessment in the light of new molecular phylogenetic and carpological analyses. – PhytoKeys 137: 1-85.

Abstract
Scorzonera comprises 180–190 species and belongs to the subtribe Scorzonerinae. Its circumscription has long been the subject of debate and available molecular phylogenetic analyses affirmed the polyphyly of Scorzonera in its wide sense. We provide a re-evaluation of Scorzonera and other related genera, based on carpological (including anatomical) and extended molecular phylogenetic analyses. We present, for the first time, a comprehensive sampling, including Scorzonera in its widest sense and all other genera recognised in the Scorzonerinae. We conducted phylogenetic analyses using Maximum Parsimony, Maximum Likelihood and Bayesian analyses, based on sequences of the nuclear ribosomal ITS and of two plastid markers (partial rbcL and matK) and Maximum Parsimony for reconstructing the carpological character states at ancestral nodes. Achene characters, especially related to pericarp anatomy, such as general topography of the tissue types, disposition of the mechanical tissue and direction of its fibres, presence or absence of air cavities, provide, in certain cases, support for the phylogenetic lineages revealed. Confirming the polyphyly of Scorzonera, we propose a revised classification of the subtribe, accepting the genera Scorzonera (including four major clades: Scorzonera s. str., S. purpurea, S. albicaulis and Podospermum), Gelasia, Lipschitzia gen. nov. (for the Scorzonera divaricata clade), Pseudopodospermum, Pterachaenia (also including Scorzonera codringtonii), Ramaliella gen. nov. (for the S. polyclada clade) and Takhtajaniantha. A key to the revised genera and a characterisation of the genera and major clades are provided.”
