Description and Ecology

They have pipe-shaped flowers and heart-shaped leaves. It is a larval host to the pipevine swallowtail and the polydamas swallowtail.[3]

Protection

Virginia snakeroot is considered an endangered species in New York, where no reports of the species were made for the century between 1895 and 1994, when it was rediscovered in the Hudson Highlands. Since then, other scattered populations have been observed in the state.[4]

The plant is also rare in Connecticut, where it is on that state's list of species of special concern.[5][6] In Michigan, its status is "Threatened."[2]

gollark: As Macron is purely functional and deterministic, when an error occurs it simply rewrites the code and time-travel-debuggings it back to the same state, until it stops erroring.
gollark: I think they can be basically equal in convenience if you can do anyhow-style error casting stuff and have try.
gollark: And bad workarounds like the errWriter thing from that blog post.
gollark: I love how they keep trying to come up with ridiculous justifications for the awful error handling.
gollark: I agree.
