仙人草(センニンソウ) Sweet Autumn Clematis

　センニンソウは、ウシノハコボレとも呼ばれます。牛がこの草を食べると、歯がこぼれ落ちるかどうか真偽はわかりませんが、有毒であることは間違いないです。他にも、ウマクワズという別名もついています。

　The Sweet Autumn Clematis is also known as "Ushinoha-kobore" in Japanese. "Ushinoha-kobore" means that teeth of a cow slip out from his/her mouth. I don't know if cows eat this grass and their teeth spill, but it's definitely toxic. It has also another name, "Uma-kuwazu" meaning horse doesn't eat it.
