Presque Isle County Michigan

Expert Response

Hello, and thank you for your inquiry.

Thank you for including pictures. Is it possible for you to take some pictures of the flower? I see some small yellow flowers... does it have 5 petals?

Looks like:
Ranunculus sceleratus L.
Common Name: CURSED CROWFOOT

But we'd need some additional information before we can be sure.

Can you compare the plant and its flowers to the info. provided at this link?

(be sure to click on "All Images" to see all of the pictures posted, otherwise you will only see one).

I'm consulting with a few of my aquatic ecologist colleagues, so if you can provide some closer up pics, and one of the flower, that would be really helpful in getting to an exact ID.

Hi again.

I also wanted to share with you this additional info. about this plan, related to safety concerns:

Wikipedia says about this species: While buttercups are toxic due to the presence of the substance protoanemonin, this applies in particular for the cursed buttercup: it is the most toxic buttercup and contains 2.5% protoanemonin. When the leaves are wrinkled, damaged or crushed, they bring out unsightly sores and blisters on human skin.
