That might be a mallow of some description, but I can't see enough
detail to be sure one way or the other.

The calyces appear to be valvate in aestivation, and persistent in
fruit, with the fruit being a schizocarp, and the foliage alternate
with the leaves palmately veined. That matches a mallow.

Unlobed leaves, and leaves with rounded (as opposed to cordate) bases
are relatively rare among mallows, but they do exist. I'm not familiar
enough with the American species to make an identification, but the
plant doesn't look incompatible with an identification as Sida spinosa.

A professional botanist (and Malvastrum expert) tells me that it's
Malvastrum coromandelianum ssp. coromandelianum.

The easy way to distinguish Sida (and segregates) from Malvastrum is
that Malvastrum has an involucel - an extra whorl of floral parts below
the calyx - of three lanceolate or spatulate bracteoles, and Sida (and
segregates) don't. Also, this Malvastrum has "plicate" leaves, and Sidas
don't.

That's a different plant.
