Corydalis

[McDonough]

More on Corydalis elata / omeiana.  I've meticulously gone through the Flora of China keys, and feel that the plant I'm growing as C. elata does indeed key closest to C. elata, and next closest to C. harrysmithii, very close but a bit less like omeiana.  The word out there is that "everything" in cultivation as C. elata is C. omeiana, but that flies in the face of the fact both species are known to be grown, omeiana and true elata. See the second link for more detailed analysis.
