[Studies on original plant of traditional Chinese drug "bai zhi" (radix Angelicae Dahuricae) and its closely related wild plants. II. Karyological and pollen morphological studies on "bai zhi" and closely related wild plants].
OBJECTIVE
To supplement cytobiological and pollen morphological data for confirming the original plant of traditional Chinese drug "Bai Zhi".


METHODS
Karyological study and pollen observation were made on "Bai Zhi" and its closely related wild plants.


RESULTS
Similarities and differences of "Bai Zhi" and its closely related wild plants were found.


CONCLUSIONS
1. 4 cultivated breeds of "Bai Zhi", Angelica dahurica, A. dahurica var. formosana, A. porphyrocaulis are really closely related plants. 2. A. dahurica var. formosana is closer to traditional Chinese drug "Bai Zhi" than others.
