I'm having some difficulties finding pictures of a weed that is
difficult to irradiate in my lawn. It grows on wirey stems with light
green fleshy leaves. The leaves have a smooth edge and pointed. The
small white flowers have four petals. It grows flat, on top of the
grass, and the mower blades miss this weed. Handpulling just breaks
the plant off at the base, and it quickly grows back in a week. It
grows in full sun. I control it by painting it with RoundUp, but that
is laborious. Unlike most weeds, it does not mind growing on top of a
thickly planted lawn. Any ideas what this could be? Thanks
