The results showed that the leaves of this plant are non-glandular trichomes types and glandular, either on the surface abaxial and adaxial and on the veins. Non-glandular trichomes consist of the monoselular and multicellular trichomes. While the glandular trichomes consist of peltate type, capitate type I and type II.
