a couple of unknowns

a couple of unknowns

Observation - a couple of unknowns - UK and Ireland. Description: Found both of these (in profusion!) on magnesian limestone grassland, near Leeds, does anyone recognise them? The dicot has what I'm hoping is a characteristic leaf shape - not so characteristic that I can identify it though - and the sedge is only 4-5cm

Found both of these (in profusion!) on magnesian limestone grassland, near Leeds, does anyone recognise them?
The dicot has what I'm hoping is a characteristic leaf shape - not so characteristic that I can identify it though - and the sedge is only 4-5cm long. Thanks in advance for your help.
