Typification of the name

Area of Science:

• Botany
• Plant Taxonomy
• Biodiversity Research

Background:

• The typification of Ranunculus rionii has been poorly documented and misleading in existing literature.
• Previous attributions of type collections to Lagger contradict the protologue, which references specimens collected by Rion.

Purpose of the Study:

• To resolve ambiguities in the typification of Ranunculus rionii.
• To identify and designate the correct type material for the name Ranunculus rionii.
• To provide a clear historical and taxonomic account of Ranunculus rionii.

Main Methods:

• Examination of original material and historical protologues.
• Review of collector's labeling practices (Lagger).
• Historical research into the discovery and collection of Ranunculus rionii specimens.
• Formal lectotypification of the name Ranunculus rionii.

Main Results:

• Original material for Ranunculus rionii has been identified.
• The specific locality of the type collection has been determined.
• Lagger's herbarium labeling methods for type specimens were analyzed.
• A comprehensive review of the discovery history of R. rionii was conducted.
• The name Ranunculus rionii was lectotypified.

Conclusions:

• The lectotypification provides a definitive taxonomic anchor for Ranunculus rionii.
• This work corrects historical inaccuracies regarding the collection and typification of Ranunculus rionii.
• The findings contribute to a more accurate understanding of Ranunculus rionii within its taxonomic context.
