Study Notes
ICNCP vs. ICBN: Key Differences
- Fundamental distinction lies in classification approaches of the ICNCP and ICBN.
- ICBN designates groups of plants as taxa (singular: taxon).
- ICNCP employs the terms cultivar and cultivar-group for cultivated plants; claims these terms are taxa, but they do not align with traditional taxonomic definitions.
Culton Concept
- "Culton" is introduced as a systematic group of cultivated plants, based on one or more criteria.
- Unlike taxa, a culton must be assigned a name under ICNCP rules.
- The term culton has yet to be fully integrated into the ICNCP regulations.
Classification Systems
- ICBN utilizes a closed classification system.
- Classification of cultivated plants in the ICNCP allows for an open system, requiring only two categories: cultivar and cultivar-group.
