Open flower about 3mm across. Fairly damp ground.
No interactions present.
I agree, seems to have 4 stamens
I count 5 in the central flower and 4 on the right (but rather hidden by petal).
You're right, five or even six! Wihtout all the characters from the rest of the plant that should make it flexuosa ...
