@coconut, You are correct that the image I selected does not exactly show epinasty in action; but what would? I was weary and did the best I could, trying to take images that were available in the ATP database.
After weeks of reading and researching each of the plant movements, I was ready to cave in. I found a good explanation for epinasty in a book by Gerard Meuant, "Flooding and Plant Growth" and since gravity can have
some effect on epinasty, I figured the heavy seed head image was close enough and better than no image at all. (Plus Trish wanted us to hurry and finish our articles in progress and she was doing a bit of 'housecleaning'.
)
Please, if you or anyone can supply a series to photo images to show epinasty it would be appreciated.
