Manicheel sounds horrible. It's in spurge family, known for skin irritation in more northern species. This is like the spurge from hell. Native and endangered in Florida. Hogweed's super scary also. It's all over North America apparently. It contains furanocoumarin, a phytotoxin, and touching the plant sensitizes skin to sunlight. It can cause severe burns, necrosis requiring amputation, and permanent blindness. A fact I just learned from looking it up: Species similar to giant hogweed, Heracleum mantegazzianum, are ALSO phototoxic. Did not know that! I thought if you could ID it as cow-parsnip or whatever, it was "safe." NOT. These include - Common hogweed, H. sphondylium -- Cow parsnip, H. maximum -- Wild parsnip, Pastinaca sativa -- Wild lettuces, Lactuca sp. -- Angelica, Angelica atropurpurea -- Queen Anne's lace, Daucus carota. Other hogweed lookalikes in Apiaceae include the hemlocks, similar appearance but feathery leaves, which go WAY beyond phytotoxicity (all parts of the plant are fatally poisonous to humans). Fun times. Steer clear! The cool thing about botany is, there's always something more to learn.
