Thank you for your question. I believe it is common purslane, described here: http://ipm.ucanr.edu/PMG/PESTNOTES/pn7461.html Hope this is helpful. Good luck!

Hmm. These are tiny plants with very strange leaves that look more like kelp. I’ve attached a couple of more pictures

Since we had no size information, we did the best we could. I suggest you take photos and samples to your county Extension office: https://extension.oregonstate.edu/kbrec Good luck!

Thanks Kristina! I will take samples to my k-falls extension office along with soil sample from my garden to get them tested too.

Let me know what they say, okay?

I took plant samples to your extension office here in Klamath Falls yesterday and the results are in: Burr Buttercup. Ugh.
The Question Asker Replied April 24, 2019, 4:40 PM EDT
Is it too late in the year to get rid of it? And what should I use to kill it? 
The Question Asker Replied April 24, 2019, 4:49 PM EDT
There are several varieties of buttercup. Did they say creeping buttercup (Ranunculus repens)?
An Ask Extension Expert Replied April 24, 2019, 6:35 PM EDT
Ranunculus testiculatus? I think thats the one. They basically just said Bur Buttercup. Now I am concerned that I'm too late to get rid of it. Can you tell me if I am too late by looking at the pictures I submitted? I'm not sure what parts are what on the plant. Obviously I know the yellow blossom, but I'm confused on if the flower itself turns into the sharp bur or the green pods that are also on the plant. Or do those pods turn into flowers too?
And again, from looking at the pictures is it too late to apply a herbicide?

I think they’re correct but you compare pictures in this Extension article, that also has control information: https://extension.usu.edu/rangeplants/forbsherbaceous/bur-buttercup Good luck!
