Premise Common taxonomic practices, which condition species' descriptions on diagnostic morphological traits, may systematically lump outcrossing species and unduly split selfing species. Specifically, higher effective population sizes genetic diversity of obligate outcrossers are expected to result less reliable phenotypic diagnoses. Wild tomatoes, members Solanum sect. Lycopersicum, commonly ...

Mimicry and extensive geographical subspecies polymorphism combine to make species in the ithomiine butterfly genus Mechanitis (Lepidoptera; Nymphalidae) difficult to determine. We use mitochondrial DNA (mtDNA) barcoding, nuclear sequences and amplified fragment length polymorphism (AFLP) genotyping to investigate species limits in this genus. Although earlier biosystematic studies based on mor...

Astragalus L. is one of the largest angiosperm complex genera that belongs to family Fabaceae, subfamily Papilionoideae or Faboideae under subtribe Astragalinae tribe Galegeae. The current study includes whole plant morphology, DNA barcode (ITS2), and molecular marker (SCoT). Ten taxa representing four species were collected from different localities in Egypt during period February 2018 May 201...
