Overview of Schistochilopsis (Hepaticae) in Pacific Asia with the Description Protochilopsis gen. nov.

Abstract

<jats:p>The taxonomic diversity center of Schistochilopsis is in East Asia, where the genus also shows the highest genetic diversity and morphological plasticity. The integrative survey of Schistochilopsis in East Asia was the main goal of the present account. Plant materials were obtained from recent collections made by authors in various parts of amphi-Pacific Asia; several types of specimens were also studied. The study includes phylogenetic reconstructions from nuclear ITS1,2, chloroplast trnL and trnG sequences, and anatomo-morphological, biogeographical, and taxonomical analyses. As a result, it was concluded that S. obscura should be transferred to Lophozia s. str. and S. grandiretis to the newly described genus Protochilopsis. Lophozia boliviensis was found to be part of the Andean–Sino-Himalayan taxon belonging to Schistochilopsis. The species status of S. hyperarctica and S. opacifolia was not confirmed. Substantial genetic variation is observed within S. incisa with possible cryptic sympatric distributed entities. The taxonomical section of the paper provides a discussion on the status, distinctive morphological traits, distribution, and ecology supplemented with the morphological description for poorly understood taxa. In the vast majority of cases, the illustrations and photographs made from the types and living material are provided.</jats:p>

Konstantinovia Is Not Monotypic, and a New Attempt to Determine Relationships in Cephaloziellaceae–Scapaniaceae Superclade (Marchantiophyta)

“…The general topology of the trees we obtained were in agreement with those presented by Vilnet et al [ 9 ], Shaw et al [ 10 ], Bakalin et al [ 11 ], and Bakalin et al [ 8 ]. In both Bayesian phylogenetic trees ( Figure 1 and Figure 2 ), the target specimen Konstantinovia sp.…”

Bryophytes of Dickson area, Western Taimyr – a model bryophyte flora for Asian arctic tundra

Zhukova & Matveyeva (2000) and found in our collection; however, molecular-pylogenetic study of the genus (Bakalin et al, 2020) showed that S. opacifolia should be considered as synonym of S. incisa. Two specimens from our collection morphologically fit to S. hyperarctica and even were tested using molecular phylogenetic data (see Bakalin et al, 2020), but also appeared mixed with morphologically heterogeneous specimens in S. incisa s.l.…”

Liverwort flora of Ayan – a gained link between subarctic and hemiboreal floras in West Okhotiya (Pacific Russia)

“…All taxa are listed below in alphabetical order. Nomenclature follows Söderström et al (2016) , with the exception for: 1) Solenostomataceae, where the narrow genus concept was adopted; 2) acceptance of Pseudolophozia distinct from Barbilophozia ; 3) new conception of Schistochilopsis genus according to Bakalin et al (2020b) and 4) the narrow species concept in Blepharostoma (the last following Bakalin et al (2020a) ). As only a few specimens of Blepharostoma species (only in pure mats) were checked by DNA analysis, clear taxonomical status of the vast majority of Blepharostoma species found as accompanying taxa (sometimes in small amounts) to other liverworts is not known definitely.…”
