- It is suggested that the ancient environment of northeast India once provided a perfect home for Nothopegia.
- The Himalayas began their dramatic rise due to tectonic movements, bringing with them sweeping changes in temperature, rainfall, and wind patterns.
- These geological convulsions cooled the northeast, rendering it inhospitable for many tropical plant species, including Nothopegia.
