Vegetative characteristics

The dwarf soldanelle is an evergreen, perennial, herbaceous plant that reaches heights of 2 to 10 centimeters. The up to 10 millimeters wide, round, kidney-shaped leaves are basal, thin.

Generative characteristics

The flowering period extends from May to August. It has an erect, leafless inflorescence stem. The terminal flowers are usually single. The hermaphrodite flowers are five-fold with a double flower envelope . The purple corollas are funnel-shaped with a length of 10 to 15 millimeters and incised up to a quarter at most (the alpine soldanelle up to the middle).

The number of chromosomes is 2n = 40.

Occurrence

The dwarf soldanelle is common in the Central Alps , Eastern Alps , Carpathians , Apennines and the Balkans . In the Northern Limestone Alps , it occurs rarely and only on decalcified soils . In the eastern parts of the Central Alps it occurs scattered, to the west its distribution area extends into the Kandertal , it is also scattered in the northern parts of the Southern Alps. In Germany, it occurs mainly in the Allgäu Alps and the Berchtesgaden Alps . In the Allgäu Alps, it occurs from 1600 meters to an altitude of 2300 meters in the Vorarlberg part of the Elferkopf winter summit.

The dwarf soldanelle prefers snow valleys , damp spots in sparse alpine lawns and rubble at altitudes of 1600 to 3100 meters. It thrives best on low-lime or lime-free, very low-nitrogen, damp and wet, humus-rich, stony, long, snow-covered loam soils . It often forms stocks with a large number of individuals at its locations. The first flowers often develop at their locations while there is still snow. It is a character species of the Salicion herbaceae association, but also occurs in snow-damp associations of the Nardion or Caricion curvulae associations.

Systematics

Soldanella pusilla was first published in 1816 by Johann Christian Gottlob Baumgarten on the basis of plants collected in Transylvania . Two subspecies are recognized:

Depending on the author, there are subspecies of Soldanella pusilla :

  • Soldanella pusilla subsp. pusilla (Syn .: Soldanella pusilla var. biflora Borbás , Soldanella pusilla f. obliqua Györffy , Soldanella pirinica F.K.Meyer , Soldanella pusilla subsp. pirinica (FKMeyer) J.Chrtek ): The plants reach a height of 4-7 cm. The corolla lobes are 0.3 to 0.7 mm wide. The corolla tube measures 9 to 18 mm in length and has a diameter of 4 to 10 (up to 12) mm at the mouth. It occurs only in the southern Carpathian Mountains of Romania and in the Rila and Pirin Mountains of Bulgaria.
  • Soldanella pusilla subsp. alpicola (FKMeyer) J. Chrtek (Syn .: S. alpicola F.K.Meyer , S. alpina var. minor Seringe , Soldanella alpina var. cylindrica Seringe , Soldanella alpina var. uniflora Steinberger , Soldanella pusilla var. parviflora Freyn , Soldanella pusilla var. chrysosplenifolia J. Murr , Soldanella pusilla f. calcicola Vierh. , Soldanella pusilla f. diversifolia Zenari , Soldanella pusilla var. carestiae Cristofolini & Pignatti ): The plants reach a height of up to 13 cm. The corolla lobes are 0.4 to 1.2 mm wide. The corolla tube measures 8 to 16 mm in length and has a diameter of 6 to 13 (up to 16) mm at the mouth. It occurs in the Alps and in the northern Apennines.
