Abstract
THE existence of pollen dimorphism in the genus Armeria was discovered by Kulczyński1 during the investigation of Dryas-containing beds near Przemyśl in Poland. Iversen2 showed that in living European material of A. maritima (Mill.) Willd., plants with Type A and Type B pollen are self-incompatible but cross-compatible. However, in the circumpolar variety sibirica Lawr.3, the pollen is monomorphic and the plants are self-compatible. According to Iversen, this may be related to a paucity of pollinating insects.
