Ecology
This procumbent, calcifugous dwarf shrub is found on exposed, stony mountain heaths on dry ridges and plateaux. Reproduction is mainly by seed, but it also spreads by rooting of the procumbent stems. Generally found from 500 to 900 m, but descends to 240 m on Ronas Hill (Shetland) and reaches 1100 m on Ben Macdui (S. Aberdeen).
Status
Native
Trends
The distribution of L. procumbens is essentially stable, and it is probably still extant in many of the 10-km squares for which there are no recent records.
World Distribution
Circumpolar Arctic-montane element, with a disjunct distribution.
