Carex divulsa subsp. leersii
This tufted perennial herb occurs on roadsides, in woodland rides, in hedge banks and open grassland, always on chalk or limestone. Lowland.
The current map of this subspecies shows a similar range to that given for C. divulsa in the 1962 Atlas, but there are many additional records, including new sites in Scotland. This reflects improved knowledge of the taxonomy of the species resulting from the work of R.W. David. However, the two subspecies of C. divulsa are linked by a range of intermediates which can sometimes make certain identification problematical.
Eurosiberian Southern-temperate element; this subspecies extends further north in Europe than subsp. divulsa.
