The debate among botanists worldwide who have had antagonistic opinions and views related to the classification of orchids is not solved yet. On the contrary, the problem is becoming even more complicated especially in Europe (between the scholars of different European countries). On the other hand, another big conflict exists between Europe and Kew. Classifications are based and build on different methodologies; Observation (comparisons of structural differences and similarities), Comparative Assessments of Mutual Relationships (Cladistic analyses) and Reproductive Isolation/Interaction (pollinator specificity as an isolation mechanism).] All these kinds of scholars’ classifications one way or another are criticized for their unclearness in taxonomy and said to have positive and negative results that can’t be completely based on.
