Valde affinis Corydalis crithmifoliae Royle sed segmentis ultimis foliis brevis, ovato oblongis, bracteis inferioris valde dissectis, sepalis 2 mm diam., denticulatis, albo-membranaceis differt. Habitu valde similis Corydalis tibeticae Hook. f. & Thoms. et Corydalis sikkimensi (Prain) Fedde, sed calcaris et fructis longis, tenusis differt.
