Pat, your plant samples have been growing in a bucket on my patio all summer.
HERE are photos of your sample specimens taken when they first arrived.
The sample plants' growth-pattern "morphed" shortly after I began their rehab in a bucket (as shown HERE).
Oddly enough, the recuperating plants never returned to the growth-pattern displayed in the original photos.
I basically think it's one of the many species of primrose, but not one that I recall seeing before. As you'll note in the photos, there were some Lepidoptera worms that seemed to really enjoy munching on this plant.
Lastly, some bladderwort seeds evidently hitched a ride with your sample-submission.
