Main Article Content
Sam bo chinh (Abelmoschus sagittifolius (Kurz) Merr.) is a precious medicinal plant that has been exploited and planted in Vietnam for a long time. However, the morphological characteristics of this plant is easy to confuse with other species of the same genus. In addition, the microscopic characteristics and medicinal powder composition of this medicinal plant have not been comprehensively described. The present investigation was aimed to determine the morphological and microscopic characters of Sam bo chinh using comparative morphology, anatomical research and medicinal powder analysis. The complete description of morphological and microscopic characteristics reported in this study will serve as valuable data for the conservation and development of this species in Vietnam.
