Enemion biternatum

Isopyrum biternatum), commonly known as the false rue-anemone, is a spring ephemeral native to moist deciduous woodland in the eastern United States and extreme southern Ontario.

[3] The plant sends up evergreen basal leaves in the fall,[4] and flower stems in the spring.

When ripe, the pod splits open on one side to release several reddish-brown seeds.

Both plants have white flowers that appear in early spring and grow in wooded areas.

[6] Enemion biternatum is listed as a schedule 1 threatened species in Canada, where only six populations were reported in southwestern Ontario.

[11] It is listed as an endangered species in Florida, where it has only been reported in Jackson and Washington counties.
