[Differentiation of Corydalis yanhusuo W. T. Wang ex Z. Y. Su et C. Y. Wu and its application].
There are differences between the big and small leaf types of Corydalis yanhusuo. The big leaf type is better and yields about 10% more than the small one. By comparing the big leaf type in terms of leaf charactistics, inflorescence and flower number, we name the small leaf one as C. yanhusuo f. floribunda.
