Abstract: Saussurea alpina (L.) DC. is a species with a large circumpolar Arctic-Alpine distribution range, recognized as highly polymorphic, due to variation in environmental factors but also possibly as a result of episodes of hybridization or manifestations of polyploidy. In the Făgăraş Mountains, on Buteanu Ridge, a population of Saussurea alpina subsp. macrophylla (Sauter) Nyman showing a significant percentage of individuals with winged stems due to leaf decurrency was discovered. Degree of decurrency ranged from low to high. This character, resulting in a winged stem, common to other species of the genus such as Saussurea porcii Degen and Saussurea parviflora (Poiret) DC, has not been reported so far in Saussurea alpina (L.) DC. Further research revealed the presence of winged stems also in other populations of Saussurea alpina from the Făgăraş Mountains.
