Virginia winged rockcress

Virginia drifts across fields, and has also been hanging around taxonomists. Not too long ago this was Arabis virginicum. But it didn't quite fit, so it became Sibara virginica. Pop quiz! Why did they use the name Sibara? Don't fret if this makes you feel a little backward. Now it has been discovered that this species is even more different genetically than previously thought. It is more related to Cardamine than Arabis. It has been moved to a different section of the family, and given its very own genus, Planodes.
