Species Myriophyllum spicatum was found by naturlvrs5 on 2009-10-06

Field Notes

We are happy because we are breathing and we are having fun on a quick field trip. When we arrived there was cars, the pond was pretty, and there was green grass. There were sticks in the water near our quadrat and leaves all around. It smelled like dirty pond water and the P.H. was 7.3. A problem we ran into was that we thought we saw a fuzzy thing in the water and it turned out to be a hunk of wood. I'm surprised about what I did or didn't find because two members of our group thought we found a dead crayfish and the other two members of our team thought it was just a weed.

Supporting evidence

We think hat we found Eurasian Water Milfoil because we found it under the water and they like it under the water.

Another reason we think we found this species is because we found it in pond and they like still water and the water we found it in was still.

The last reason we think we found it is because it has whorled leaves like in the pictures that we looked at.

Good observation

Thank you so much for the detailed photos, based on the fork divided leaf, I feel confident that this is not Eurasian Milfoil. Its certainly a close relative though. Keep your eyes open, your vigilance is appreciated.

Aquatic plant identification can be tricky. You're right that the leaves of the submersed plant you found are arranged in whorls just like Eurasian watermilfoil, BUT take a closer look at the branching pattern of each leaf.

I zoomed in on your photo and saw that they are actually fork-divided. Eurasian watermilfoil has feather-divided leaves. Do you see the difference? I find the diagrams on the species cards really helpful seeing these tiny but critical differences.

Glad you're out there looking for submersed aquatics! Did you throw the weed weasel? Wicked far?!

Thanks for the comment!!!

Thanks for the comment!!! What do you think it is? We actually found it floating close to the shore!
