Description

Original: "You can't see the achenes, but I did look at them. They were light brown, just over 1mm in length, and with a small differentiated tubercle nearly as wide at its base as the achene but only about 1/5 the length of the body of the achene."

I looked at more material, most tubercles are about or just over 1/4 the length of the achene and not depressed on their shoulders.
