Summary

Study on Morphological and Microscopic Characteristics of Codonopsis javanica (Blume) Hook. f. & Thoms. in Vietnam

Dang sam - Codonopsis javanica (Blume) Hook. f. & Thoms. is a medicinal plant widely used in traditional medicine in some Asian countries. In Vietnam, morphological descriptions of this species weren’t existed among published works, especially its anatomical structure has not been described in comprehensive way. Thus, study on morphological and microscopic characteristics of 28 Dang sam samples collected in 9 locations of 7 provinces in Vietnam has been conducted. Study results showed that among collected samples there are variations in leave, fruit and flower morphology, especially in the number of petals, stigma lobes and stamens, position of the sepals on ovary. Complete description on morphological and microscopic characteristics reported in this study will be helpful for conservation and development of Dang sam in Vietnam.

Keywords: Morphology, Microscopic characteristics, Codonopsis javanica, Dang sam.
