i can't necessarily point it out. but i'm in the same boat. looking up weeds is extraordinarily difficult. if you find someone that can identify let me know. ranchgal@snappydsl.net. I'm trying to figure out what made one of my livestock ill...

here are some sites i've found that might help you. I know i've seen that two toned leaf before.

anyone else care to take a shot at these weeds? I'll greatly appreciate it.

The second one looks like spotted spurge. Very hard to get rid of.

I initially thought of spotted spurge, but according to all the info that I have found it has red "spots". This one has cream or white sports in the middle of the leaf, so I have reject it as a possibility.

Anyone else?
