description
in Anton Hartinger , Atlas of the Alpine flora (1882)
The Clusius primrose grows as a perennial herbaceous plant and reaches heights of 2 to 5 centimeters. The aboveground parts of the plant are densely covered with short, colorless glandular hairs of 0.1 to 0.5 millimeters in length.
The basal leaves are elongated-egg-shaped with a length of 1.5 to 6 centimeters. The smooth edge of cartilage is narrow and whitish. The upper side of the leaf is shiny, light green and the underside of the leaf is gray-green.
The narrow-lanceolate bracts reach at most to the center of the calyx and with a length of 4 to 10 millimeters are usually longer than the flower stalks. The 8 to 15 millimeter long chalice is tubular-bell-shaped and not divided up to the middle. It has blunt tips. The crown is bright purple and usually purple when it fades, with a white throat and a deeply edged coronet. The diameter reaches 20 to 35 millimeters. The corolla tube is 9 to 16 millimeters long.
The flowering period extends from May to June.
The number of chromosomes is 2n = 156.
Occurrence
This limestone plant is endemic to the Northern Limestone Alps . The distribution area of the Clusius primrose includes the Berchtesgaden Alps , as well as the area from Salzburg (rarely) through Upper and Lower Austria to Styria . An isolated occurrence exists in the Lower Tauern.
The Clusius primrose thrives at altitudes between 1700 m and 2200 m , but often descends in the area to 600 m . Lean lawns in stony, rocky places and snow valleys are preferred. It is a character species of the Potentilletum clusianae from the association of moist limestone joints (Cystopteridion fragilis).
