No ID, but it sounds like a candidate for some broadleaf spray, which
would be less laborious than individual RoundUp treatment. I have
something similar, and just haven't been able to find a small
hand-sprayer of Weed-b-gon to treat it.
I've tried Spectricide and Weed-B-Gone. They are effective with two
or three applications on this particular weed. I've been fighting
this weed for many years, and now I yank them out (break them off)
while I mow and out them into a plastic bag. I'd like to learn more
about this weed, but not having identified it makes it difficult to
find on the web. I thought it is knotweed or pigweed (the leaves look
like a pig's ear). I'm patient and still searching. Anyone know
about a good web site for weed identification?
You could try www.scotts.com . Or you could try bring a specimen to your
local county extension and they should be able to help you.

You may or may not want to feel guilty for calling this uncommon but
widespread native plant a weed. If it was a bit more showier, it would be
grown as a garden plant.
It is Diodia virginiana L., commonly called "Buttonweed".
The paired leaves and four petaled white flowers are characteristic.
Since it is a plant that favors wet soil, your lawn is probably getting a
bit too much water.
It is Buttonweed (Diodia Virginiana L.) and it grows in the lower
parts of the yard where there is a lot of water (a natural spring-fed
pond and mountain brook are nearby and I have a crawfish problem in
the yard). I've been diligent about handpicking it before it
flowers, but there's always new seeds coming in. Thanks to all that
That's it! Buttonweed. And it's sure vriginiana. "Too much" water may
not be a requisite. It's certainly been a lot more vigorous in this
rainy spring/summer, but appears and thrives even in dry years.
Hmm. Checking Cereoid's URLs with mentions of seeds leads me to
believe if we can see the flowers, we've waited too long to apply some
form of control. I'll bet a couple of seasons of zapping this as soon
as we can recognize the leaves might be quite effective.
