One of the identifying features of germander speedwell, is the two rows of hairs growing in a line along opposite sides of its stem (left, x20 approx.).
The plant's scientific name is Veronica chamaedrys; Veronica after the saint of that name, chamaedrys from the Greek for dwarf oak. Perhaps this refers to the lobed leaves.
It grows in grassy places, including our front lawn. I wouldn't normally pick wild flowers but the lawn is now due for mowing. Far from feeling that it's about time I applied weed killer I love to see the blue flowers of speedwell dotted amongst the daisies and buttercups.
