Article Synopsis
  • The Cymbellaaffinis / Cymbellatumidula / Cymbellaturgidula species complex faces taxonomic challenges due to its diverse morphology and absence of clear type designations.
  • Fifteen taxa names, across five species, were reassessed for their taxonomic status and designated lectotypes based on original material.
  • The study utilized light and electron microscopy, leading to four new combinations for reclassifying infraspecific taxa within the complex.
