Chemical polymorphism of essential oil in Thymus praecox ssp. arcticus (Lamiaceae) from Greenland
The chemistry of the essential oil of Thymus praecox Opiz ssp. arcticus (E. Durand) Jalas from Greenland was studied with the intention of comparing it with the results obtained earlier from Icelandic material. All the 17 samples collected at different localities of South–West Greenland were found t...

The chemistry of the essential oil of Thymus praecox Opiz ssp. arcticus (E.
