Comparative Study of Leaf Anatomy and Micromorphology of Selected Justicia Species from Peninsular Malaysia

Justicia has been recognized as one of the largest genera in Acanthaceae family with 600 species have identified. Most researchers problems identifying especially if samples are incomplete. Other than that, there is no comprehensive study on species, Peninsular Malaysia. Therefore, a leaf anatomy and micromorphology three selected which adathoda, gendarussa procumbens were conducted order to assess anatomical micromorphological variations that would be useful identify plant species. The methods used this involved several such cross-section using sliding microtome observation under scanning electron microscope (SEM) for epidermis abaxial adaxial surfaces. Collenchyma, sclerenchyma mucilage cells can found either petiole or midrib all studied. Amphistomatic stomata also recorded examined. Meanwhile, differences discovered study, including type trichomes, pattern vascular bundles, epicuticular wax structures, cuticle ornamentation presence cystolith cells. In conclusion, characteristics some Malaysia identified micromorphology.
