New flower of Scotland discovered in Shetland

Researchers from Stirling University have discovered a new plant.

Shetland's monkeyflower was found during fieldwork by a roadside near Lerwick.

Scientists believe the discovery could further our understanding of polyploids and early-stage evolution.

Dr Mario Vallejo-Marin, from Stirling University, told the BBC the plant had duplicated its own genome, making it larger than its ancestors - the yellow monkeyflower or mimulus guttatus without hybridisation from any other plant.
