When Chuck Pearson found these plants at Ives Preserve, we thought they were just chervil. More careful examination revealed bristly ovaries below those petals. That just wasn't right! The Michigan keys don't work for a plant with bristly ovaries and fruit with the rest of the characters you see here. The ultimate answer to this puzzle was bur-chervil. First time it's been documented in Michigan. Fun! So what did Chuck do after he found bur-chervil? No, it didn't involve Disney. He killed it. We don't need any more Eurasian aliens in the Preserve. Bur-chervil has also been found in AR, AZ, CA, CT, DE, GA, ID, IL, IN, LA, MO, NC, NE, NJ, NY, OH, OK, OR, SC, TN, VA, WA, WV, WY, BC, and ON. Ives Preserve, Lenawee Co MI, 5/15/21.
