Oxypolis canbyi
Also called Canby's cowbane, Canby's Dropwort, Water Dropwort
Tiedemannia canbyi (syn. Oxypolis canbyi) is a rare species of flowering plant in the carrot family known as Canby's dropwort and Canby's cowbane. It is native to the southeastern United States, where it occurs on the Atlantic coastal plain from North Carolina to Georgia, as well as the Chesapeake Bay area. It is threatened by the loss of the wetland habitat in which it grows. It is a federally listed endangered species of the United States.
The larva of the black swallowtail butterfly (Papilio polyxenes asterius) feed on the plant. They eat the stem, separating the inflorescence and sometimes preventing sexual reproduction; however, the plant more often reproduces asexually via cloning.
