Objective:
To provide a scientific evidence for the identification of the section Cruciata Gaudin.
Methods:
Seed morphology of the section Cruciata Gaudin in different regions from Gansu were studied by means of scanning electronic microscopy (SEM).
Results:
The seeds of section Cruciata Gaudin had relative conformability in terms of shape,size and ornamentation. But the reticulate cell of Gentiana dahurica was obviously wider than those of other species.
Conclusion:
This study provides some useful information for classification and identification of section Cruciata Gaudin.
