A chemotaxonomic study of the Nordic Papaver species belonging to the Scapiflora group has been carried out by means of gas chromatography (GC), mass spectro‐graphy (MS), and thin layer chromatography (TLC). The data obtained were analysed by the aid of hard and fuzzy clustering. Of the alkaloids identified, protopine and allocryptopine were found in all species investigated (i.e. Papaver radicaium ‐ including all subspecies ‐ P. dahlianum, P. lapponicum , and P. laesiadianum ). Protopine and allocryptopine were the only alkaloids found in P. dahlianum, P. lapponicum , and P. laesiadianum . In addition O ‐methylthalisopavine was found in all investigated subspecies of P. radicatum; reframine in P. radicatum sspp. ovatilobum, gjaerevollii, groevudalense, intermedium, oeksendalense, radicatum, relictum , and subglobosum; reframidine in ssp. hyperboreum; cryptopine in sspp. ovatilobum, gjaerevollii, groevudalense, relictum, subglobosum, macrostigma , and hyperboreum; muramine in sspp. macrostigma and hyperboreum; and amurine in sspp. relictum and subglobosum . These chemotaxonomic results confirm the systematics of the Nordic Papavers of the sect. Scapiflora introduced by Knaben who based the taxonomy on morphological and cytological characteristics. Moreover, the content of alkaloids in the different isolated Nordic Papaver populations may be of plant geographical importance. There are, for instance, a marked chemical difference between all the South Norwegian subspecies of P. radicatum and the North Norwegian P. radicatum ssp. subglobosum on one hand and the rest of the North Norwegian subspecies on the other.
