  • Photosynthesis metabolism in the Compositae: Current knowledge and future directions
    TAXON (IF 2.817) Pub Date : 2021-01-11
    Carolina M. Siniscalchi; Robert D. Edwards; Jorge L. Gomez; Erika R. Moore; Jennifer R. Mandel

    Compositae accounts for ca. 10% of all flowering plants, being found in nearly all types of habitats worldwide. The family is particularly diverse in markedly dry and seasonal habitats, raising questions about what processes led to diversification in these challenging environments. The presence of C4 and CAM metabolism in some Compositae taxa has been known since the 1970s, and although some of these

  • Lihengia: A new genus of Asteraceae distinct from Dubyaea
    TAXON (IF 2.817) Pub Date : 2021-01-11
    You‐Sheng Chen; Lian‐Sheng Xu; Rui Ke; Aj Harris; Hui‐Min Li

    A new genus, Lihengia, is established for two species presently treated within Dubyaea, which is proved to be paraphyletic in the present study, even after exclusion of Lihengia. Dubyaea is a genus of about 15 species endemic to the Sino‐Himalayan region that are treated within subtribe Crepidinae of tribe Cichorieae within Asteraceae. Stebbins suggested that Dubyaea may contain species representing

  • Phylogenomics supported by geometric morphometrics reveals delimitation of sexual species within the polyploid apomictic Ranunculus auricomus complex (Ranunculaceae)
    TAXON (IF 2.817) Pub Date : 2020-10-31

    Species are the basic units of biodiversity and evolution. Nowadays, they are widely considered as ancestor‐descendant lineages. Their definition remains a persistent challenge for taxonomists due to lineage evolutionary role and circumscription, i.e., persistence in time and space, ecological niche, or a shared phenotype. Recognizing and delimiting species is particularly methodically challenging

  • Phylogenetic relationships and sectional delineation within Gentiana (Gentianaceae)

    Gentiana is a sub‐cosmopolitan temperate genus among the most species‐rich in Gentianaceae. Although molecular data (produced via Sanger sequencing) allowed the resolution of phylogenetic relationships between Gentiana and other genera in subtribe Gentianinae, the validity of sections within the genus remains largely untested. In this study, we evaluated the monophyly of all 14 sections attributed

    Campanula sect. Quinqueloculares (Campanulaceae), consisting of ca. 39 mostly chasmophytic species, is one of the most morphologically variable groups in Campanula and includes numerous endemics occurring mostly in Greece and/or Turkey. In this molecular study, we aim to test the monophyly of C. sect. Quinqueloculares and provide divergence time estimates to generate hypotheses into the historical

    Montsechia vidalii is an abundant plant fossil from the Barremian of northeastern Spain. Systematic affinities have been suggested with several living plant clades (liverworts, horsetails, conifers, Gnetales), particularly with angiosperms. We provide detailed descriptions, documentation, and discussion of morphology and histology based on hand specimens of isolated leafy stems with fruits examined

    According to Rec. 40A.1 of the Shenzhen Code (Turland & al. in Regnum Veg. 159. 2018), the indication of the nomenclatural type should immediately follow the description or diagnosis and should include the Latin word “typus” or “holotypus”. However, Art. 40.6 states “indication of the type must include one of the words “typus” or “holotypus”, or its abbreviation, or its equivalent in a modern language”

    The current International Code of Nomenclature for algae, fungi, and plants (Shenzhen Code; Turland & al. in Regnum Veg. 159. 2018) prescribes how to form the genitive case for personal names that are not of Latin form and that end in a consonant other than er.

    Each of two or more names that apply to the same taxon are synonymous to one another. One of them may or may not be a correct name for that taxon. In our opinion, this is not clearly reflected in the definition of “synonym” in the Glossary of the Shenzhen Code (Turland & al. in Regnum Veg. 159. 2018).

    Targeted capture of nuclear genes increasingly contributes to unravelling phylogenetic relationships that hitherto remained unresolved because of limitations of traditional Sanger sequencing. In particular, the study of tropical plant families has been compromised because they often rely on highly degraded DNA obtained from herbarium specimens.
