Good day all,

For several weeks, I've noticed a patch of my lawn (about 1 metre diameter)
that is a yellower shade of green than the rest of the lawn. On closer
examination, I find that this patch has been invaded by an unusual-looking
variety of clover which has totally smothered all the grass that was once
there. Like your usual clover, each leaf is in triplicate, but the leaves
are smaller and more triangular, and each leaf has a brown speck in the
middle. It seems to be spreading via runners. The dark brown runners are
particularly strong and wirey. Is anyone familiar with this invader, and
can you suggest a way to eradicate it?

Many thanks, on this grey drizzly day!
