The Dolomite Mannsschild ( Androsace hausmannii ) is a species of the genus Mannsschild ( Androsace ) in the family of Primrose (Primulaceae).
features
The Dolomiten-Mannsschild is a perennial plant that grows in flat, small pads. It is covered with no more than 0.2 millimeters long, two- to three-part hair. The leaves are arranged in a few dense rosettes. They are 5 to 10 millimeters long, up to 1.5 millimeters wide, narrow-lanceolate, blunt and hairy on the edge and on both sides.
The flowers arise individually in the axils of the uppermost rosette leaves. They barely rise above the leaves. The flower stalks are 1 to 12 millimeters long. The calyx is divided up to the middle and 3 to 4 millimeters long. The crown is 4 to 5 millimeters wide and mostly white in color. It is tinged with pink on the outside, has a yellow throat and often slightly edged lobes. The corolla tube is shorter than the triangular calyx teeth.
The flowering period extends from June to August.
The number of chromosomes is 2n = 40.
Occurrence
The Dolomites-Mannsschild occurs in the Eastern Alps from Presolana to the Steiner Alps and from the Berchtesgaden Alps to Styria . The species grows on limestone rock and rubble at altitudes up to over 3000 meters.
Locations and distribution in Central Europe
The Dolomiten-Mannsschild needs lime-rich subsoil and a well-sunny location.
It colonizes coarse debris rich in clay and fine earth, but it also goes into rock crevices filled with fine earth. Overall, it is rare in Central Europe; it occurs only in the southern Limestone Alps from the Presolana or from South Tyrol eastwards to the Gaital Alps, in the eastern chains of the Northern Limestone Alps there are isolated stocks near Liezen and Lofer and in Berchtesgaden. He prefers heights between about 1800-300 m. It thrives in companies of the Potentillion caulescentis association.
The fragmentation of the area still shows today that the species used to have a larger distribution area in the Eastern Alps.
