hydrilla look-alike
Thanks for keeping an eye out for hydrilla. It's hard to tell for absolute certainty that this is NOT hydrilla but based on the photographs I believe the identification is correct.
A few thoughts you might consider in future searches for hydrilla:
-You described leaf shape as a "bundle;" I'm not familiar with that term. Rather than leaf shape, are you referring to the leaf arrangement, i.e., how the leaves attach to the stem? If that's true, I suggest you use the term "whorled" next time.
-You note that the leaves were 7 to 13 cm -- were the leaves themselves that long or were the stems that long? 7 to 13 cm is long for hydrilla or it's look-alike, common waterweed (Elodea sp).
-You also note that the plant you found has more leaves than the picture of hydrilla. If you're talking about the number of leaves per whorl, it's usually the other way around. That is, hydrilla usually has a greater number of leaves per whorl than does the native waterweed.
Thanks again -- keep searching!
Nice job
I find it a relief that you haven't found hydrilla. If so, it would be pretty bad!
