RESUMO
Alternanthera brasiliana (L.) O. Kuntze, Amaranthaceae is a Brazilian perennial herb employed as analgesic and anti-inflammatory in the traditional medicine. This work has analysed the morpho-anatomy of the leaf and stem, in order to supply knowledge to the medicinal plant identification. The botanical material was fixed, freehand sectioned and stained according to usual microtechniques. The leaves are simple, entire, decussate, oval-lanceolate and purple, presenting uniseriate epidermis, pluricellular non-glandular trichomes coated by papillose cuticle, anomocytic and diacytic stomata on both surfaces; the mesophyll is dorsiventral, with collateral vascular bundles and druses. The stem, in secondary growth, has the dermal system similar to the leaf; the angular collenchyma alternates with the chlorenchyma; it occurs druses and a cambial variant, consisting of concentrical arcs of extra-cambia outside the first cambium and aligned vascular bundles in the pith
