The paper analyses the distribution and occurrence conditions of Loiseleuria procumbens in the Spanish Pyrenees. The species represents a typical arctic-alpine element in the flora of Europe. In the Pyrenees it reaches its southernmost European localities. The Pyrenean populations of the species are not numerous in the majority of the localities. L. procumbens occurs most frequently in the alpine and subalpine zones, at altitudes between 2100 and 2650 m, with a minimum at 1750 m and a maximum at 2900 m. It has been reported nearly exclusively in the siliceous substrata, and predominantly on the north-facing slopes, on the regosols and/or on flat tops of rocks. It forms its own communities, mostly included into the Loiseleurio-Vaccinion alliance, and rarely enters associations of the Festucion airoidis and Rhododendro-Vaccinion alliances. Its typical community, Cetrario-Loiseleurietum procumbentis, is found only in the eastern and central parts of the Spanish Pyrenees.

Loiseleuria procumbens: differentiation of the seed size of some chosen European populations

Loiseleuria is a monotypic genus of the family Ericaceae. The only species of this genus, L. procumbens, is an arctic-alpine element with a circumpolar distribution, found in the subarctic zone and in mountain ranges located further south. Results of earlier research on the structure of its fruits and seeds (Szkudlarz 2002) suggested that there are some differences between populations from different parts of its natural range of distribution. To verify this hypothesis, seed dimensions in samples from distant localities were compared in this study. The presented results indicate that in populations from Scandinavia seeds are generally shorter than in central Europe.
