Red Gall - Euura
Copyright © 2011 Dick Palmer

Red Gall - Euura
Kent, Clark Lake Park, King County, Washington, USA
June 5, 2011
Size: 7 to 10 mm in dia.
I have included three photos of this gall, first the top of the leaf, 2nd the underside of the leaf, and third a context shot to show what kind of plant I found this gall on. I do not know what the plant is, but I've seen it often. I am told it is some kind of twin-berry, but I have my doubts. As to what created the gall, I haven't a clue. All I can tell you is that the plant is growing in a protected wetland zone.
