  • Morphometrics in the Recurved Corolla Clade of Burmeistera (Campanulaceae) Clarifies Species Limits and Identifies a New Species
Title: Morphometrics in the Recurved Corolla Clade of Burmeistera (Campanulaceae) Clarifies Species Limits and Identifies a New Species
Abstract—The genus Burmeistera consists mostly of cloud forest species occurring from Guatemala to Peru. Molecular work on this group has revealed previously established subgeneric groupings to be non-monophyletic, while also identifying several monophyletic groups with recognizable synapomorphies. One such monophyletic group is a clade of species with recurved corolla lobes which contains three species: B. crispiloba, B. sodiroana, and B. succulenta. As many as nine names have been recognized previously for these species, though the most recent taxonomic treatments recognize only these three. Additional collections of these species made in the last forty years have uncovered phenotypic variation showing that characters traditionally used to differentiate them no longer do so clearly and suggest the possibility of introgression between them. Here, we report morphometric analyses of herbarium specimens of the recurved corolla clade, using both hierarchical and normal mixture model-based clustering methods to test the current species hypotheses. Our results support the recognition of the three known species plus the newly described Burmeistera kitrinaima sp. nov. We provide complete descriptions of all four species, and include photographs, distributions maps, taxonomic discussion, and an identification key. Keywords—Andes, biodiversity, cluster analysis, hybridization, taxonomy.  more » « less

    The genusPseudogymnoascusincludes several species frequently isolated from extreme environments worldwide, including cold environments such as Antarctica. This study describes three new species ofPseudogymnoascus—P. russussp. nov.,P. irelandiaesp. nov., andP. ramosussp. nov.—isolated from Antarctic soils. These species represent the firstPseudogymnoascustaxa to be formally described from Antarctic soil samples, expanding our understanding of fungal biodiversity in this extreme environment. Microscopic descriptions of asexual structures from living cultures, along with measurements of cultural characteristics and growth on various media types at different temperatures, identify three distinct new species. In addition, phylogenetic analyses based on five gene regions (ITS, LSU, MCM7, RPB2, TEF1) and whole-genome proteomes place these new species within three distinct previously described clades:P. irelandiaein clade K,P. ramosusin clade Q, andP. russusin clade B. These results provide further evidence of the extensive undescribed diversity ofPseudogymnoascusin high-latitude soils. This study contributes to the growing body of knowledge on Antarctic mycology and the broader ecology of psychrophilic and psychrotolerant fungi.

    Abstract Speciation processes in plants can be difficult to evaluate, but are essential to understanding evolutionary processes that lead to diversification. Determining the juncture at which a genetically and/or morphologically divergent population can be reliably considered a separate species is often challenging. This is particularly so with respect to recent divergences amongst closely related taxa wherein factors such as incomplete lineage sorting may yield confounding results. Taxa in theCymopterus terebinthinus(Apiaceae) species complex have long puzzled botanists. Named entities in this group display similar, yet apparently distinct morphologies that have been classified as varieties under various generic names highlighting long‐standing nomenclatural instability. Previous phylogenetic studies have challenged the monophyly of this complex. This study aims to clarify taxonomic boundaries and infer evolutionary relationships among the fourC. terebinthinusvarieties andC. petraeusby applying phylogenetic inference and incorporating ecological, morphological, and geographical evidence. We sampled from populations of all varieties ofC. terebinthinusandC. petraeusfor target capture with the Angiosperms353 bait kit. We performed phylogenetic analyses with maximum likelihood (RAxML and IQ‐TREE) and coalescent‐based phylogenetic analysis (ASTRAL). We also conducted principal component analysis of soil samples and climatic variables. We find thatC. terebinthinusand its varietal infrataxa comprise a monophyletic clade that includesC. petraeus. Clade groupings correspond to previous taxonomic assignments and morphology. Clades are often closely associated with geographical variables and at times correlated with ecological variables. Exceptions to this are here attributed to various evolutionary factors that often confound other phylogenetic analyses such as incomplete lineage sorting, introgression, and paralogous loci. Our findings suggests that geographical factors might play a major role in genetic and morphological differentiation in this complex. Despite finding well‐supported clades that correspond to defined morphological characters; further sampling amongC. petraeuspopulations is required to make taxonomic decisions.

    Six species of Burmeistera H. Karst. & Triana are described as new from Ecuador: B. chrysothrix Mashburn & Muchhala, B. crocodila Mashburn & Muchhala, B. erosa Mashburn, B. lingulata Mashburn & Muchhala, B. sierrazulensis Mashburn & Muchhala, and B. valdiviana Mashburn. These discoveries bring the total number of Burmeistera species in Ecuador to ca. 47. Descriptions are given for each species, as well as diagnoses to differentiate them from other Burmeistera. Also provided is a discussion of each species’ etymology, phenology, and ecology, a list of all specimens examined, and distribution maps and photos, when available.

    Abstract—Podostemaceae are a clade of aquatic flowering plants that form important components of tropical river ecosystems. Species in the family exhibit highly derived growth forms and high vegetative phenotypic plasticity, both of which contribute to taxonomic confusion. The backbone phylogeny of the family remains poorly resolved, many species remain to be included in a molecular phylogenetic analysis, and the monophyly of many taxa remains to be tested. To address these issues, we assembled sequence data for 73 protein-coding plastid genes from 132 samples representing 68 species (∼23% of described species) that span the breadth of most major taxonomic, morphological, and biogeographic groups of Podostemaceae. With these data, we conducted the first plastid phylogenomic analysis of the family with broad taxon sampling. These analyses resolved most nodes with high support, including relationships not recovered in previous analyses. No evidence of widespread, well-supported conflict among individual plastid genes and the concatenated phylogeny was observed. We present new evidence that four genera (Apinagia,Marathrum,Oserya, andPodostemum), as well as four species, are not monophyletic. In particular, we show thatPodostemum flagelliformeshould not be included inPodostemumand is better recognized asDevillea flagelliformis,and thatMarathrum capillaceumis embedded withinLophogynes.l. and should be recognized asLophogyne capillacea. We also place a previously unsampled and undescribed species that likely represents a new genus. In contrast to previous studies, the neotropical generaDiamantina,Ceratolacis,Cipoia,andPodostemumare resolved as successive sister groups to a clade of all paleotropical Podostemoideae taxa sampled, suggesting a single dispersal event from the neotropics to the paleotropics in the history of the subfamily. These results provide a strong basis for improving the classification of Podostemaceae and a framework for future phylogenomic studies of the clade employing data from the nuclear genome.
