Double-spiked Narrow-leaf Cattail
From Steve Young – When we were in Catskill Marsh last week we came across many examples of narrow-leaf cattail with double spikes that joined together to form the gap you see in the photo below (sorry for the bad focus).
I had never seen this before and would like to know if anyone else has seen it. If you have you may leave a comment below.

I have several of these cattails growing in my ditch. Mine are even more bizarre, they have 4 spikes growing on them. I can send photos if you would like. I do have people researching them for me. If anyone knows what makes these cattails deform this way, please let me know. They are very interesting and unique.
