To valmue-arter på Svalbard, og litt om fjell- og polarvalmuer
Morphological investigations confirm that there are two species of Papaver in Svalbard: P. dahlianum and P. cornwallisense. The two most distinctive diagnostic characters are the number of stamens and the length of papillae on the stigmatic rays. Papaver cornwallisense has few stamens, usually 16 bu...
