Plant ID?

Here is a plant I have growing in my garden. I forgot to label it and now am not sure what it is. I'm thinking it could be a Corydalis?? See photos; particularly the closeup of the unusual flower.

 

Could it be a Thalictrum species ? Maybe a male T. dioicum, early meadow rue ?
I don't think it's Corydalis.

 

Thank you so much.

 

You're welcome, interesting plant.

 

Oooh!
I grow several Thalictrum but haven't see Thalictrum dioicum.
Amazing stamens. Love it.
