Abstract: 
Lion's ear [Leonotis nepetifolia (L.) R. Br.] is a Vietnamese medicinal plant that has been described in basic morphology and isolated for a number of chemical compounds. This study aims to supplement a database of morphology, micro-anatomy and antibacterial abilities of this species. Micro-anatomical analysis was based on a double staining method microscopic dimensional measurement of plant.  The antibacterial capacity was based on the diameter of the inhibitory zone. The results showed that the plant had the characteristics of adapting to the dry and light conditions of the region. Leaf extract at the content of 4.8 to 8.0 mg had the best inhibitory ability on 5 strains of bacteria B. cereus, S. aureus, E. faecalis, P. aeruginosa, and E. coli. The inhibition zone diameters were 0.27, 10.33, 5.00, 3.80 and 2.23 mm, respectively.
