Abstract

Campanula rotundifolia (Harebell) is widespread and cytologically diverse in the British Isles. Hexaploids have an oceanic, westerly/northerly distribution, tetraploids are more easterly/southern, and occasional pentaploids occur. It tolerates diverse climatic and soil conditions, becoming rare on fertile lowland clays, where there are more vigorous competitors. It is threatened by agricultural intensification, reversion of grassland to scrub, disturbance, and atmospheric pollution.
