This work shows the morpho-anatomical study of leaf and stem of Microlicia hatschbachii Wurdack (Melastomataceae). Its leaves are elliptic to oval-elliptic, with entire margin, acute apex and rounded symmetrical base. The leaf blade is amphistomatical with anisocytic and anomocytic stomata, in transection the epidermis is uniseriate with isodiametric cells and presence of several glandular trichomes. The mesophyll is isobilateral with bicollateral vascular bundles surrounded by some sclerenchymatic cells in midrib. The stem has a quadrangular to circular transection and uniseriate epidermis with trichomes like ones of leaf. Several druses of calcium oxalate are found in the leaf and stem.

Keywords : Microlicia hatschbachii; Melastomataceae; morpho-anatomy.
