Sempervivum

MONTANUM ssp. CARPATHICUM (Wettstein ex Prodan) Berger, 1930

Synonym : Sempervivum carpathicum  Wettstein ex Prodan (1923)

Distribution : Carpathians (Slovenia, Romania, Poland, Ukrainia).

Description (according to 't Hart, Bleij & Zonneveld in IHSP, 2003) :

Rosettes 3 - 4 cm in diameter; stolons short.

Leaves obovate, broadest near the tip, cilia almost as long or somewhat longer than the hairs of the pubescence, to 0.2 mm long.

Flowers : Petals dull purple.

Cytolog: 2n = 42

Intermediate between ssp. burnatii and ssp. stiriacum.

Note :

As result of a multivariate morphometric study of the Sempervivum montanum group in the Western Carpathians R. Letz (2002)* published two new names for Sempervivum montanum ssp. carpathicum :

- S. carpathicum ssp. carpathicum

- S. carpathicum ssp. heterophyllum

explaining that "Carpathian populations represent the third distinct species in the S. montanum group, isolated from the diploids of S. montanum in the Alps by a barrier of the tetraploides - S. stiriacum." The subspecies "differ in respect of the size of rosettes, rosette leaves and the colour of the leaves [....] they are neither conspecific with the morphologically different diploid populations of the Central and Western Alps, the Pyrenees, the Appenines and Corse, nor with the tetraploid populations of the Eastern Alps (S. stiriacum Wettst.)."
