The chromosome crunchers are at it again. They take their samples, sequence the DNA, run the results through their super computers, and have an answer. Often it agrees with the old classifications, but many times it doesn't. This one didn't, and it became Capnoides. And sometimes if they do it again, they don't agree with themselves. When I just looked this up on the USDA plants site to find state listings for protection, I found that rock harlequin was listed under an older name, Corydalis sempervirens. What's up, people?
