[MAIPC] Corydalis incisa: be on the lookout

[Margaret Chatham]

Purple or white flower color looks like a pretty clear identifier ‹
according to Flora of Virginia, we only have one native Corydalis: the much
smaller yellow-flowered C. flavula. C. sempervirens has pink flowers ( & has
been renamed Capnoides sempervirens). Then there is Fumaria officinalis with
round seedpods ‹ and it isn¹t native.
