esshup - That SeaGrant page does not even mention turions although it does show a turion. I think they consider the turion a plant fragment which technically it is a fragment of the plant. The wording on the page is general and it does not distinguish the growth activity or ability among stems, leaves, and turions. I defy anyone to show me how a leaf. stem or leaf & stem will sprout into a new plant for the specie CLPW. If we pin the author down to specific details I think they were referring to a turion as a plant fragment. I did not get an A+ in Aquatic Vascular Plants in grad school for being a dummy.
