Identification of Yi Medicine Mubaribo

[Objectives] To identify original plant and traits of Yi medicine Mubaribo( Verbenae herba) and provide effective experimental data for its identification and application.[Methods]The original plant,traits,and microscopic identification were used.[Results]Stem was square,the edges of basal leaves usually had rough saw teeth and notches; most cauline leaves were three parted,edges of lobes have uneven saw teeth,both edges had hard hair; spikes were terminal and axillary,thin and delicate; corolla was light purple to blue. Epidermal cells of stem were long polygonal or quasi-rectangular,vertical wall was straight with pores; lower epidermal cells of leaves were vertical to wall and took on wavy bending; pores were infinitive or anisocytic; 3-5 subsidiary cells; 4 glandularscale head cells,stalk single cell,non-glandular single cell; pollen grains were quasi-circular or quasi-triangular,smooth surface,and 3 germination apertures. [Conclusions] Yi medicine Mubaribo has distinctive identifying characteristics in original plant,traits,and microscopic tissues. This study is expected to provide certain reference for identification of original plant and medicine and formulation of quality standard for Yi medicine Mubaribo,and to provide basis for its further research and development.
