【 摘 要 】

Baccharis glaziovii Baker, Asteraceae, also known as carqueja or carqueja-arbustinho, is a native shrub of Brazil that reaches 0.5-2.5 m in height. It is a dioecious species that blossoms from September to December. This species has cladodes, which are winged stems that belong to the “carquejas” and are widely used indiscriminately by the population due to their gastric and diuretic properties. Carquejas are included in section Caulopterae and are difficult to identify even for taxonomists or Baccharis specialists. In the present study, a morpho-anatomical (cladodes and leaves) analysis of the medicinal plant was undertaken to improve its identification and add to the knowledge of section Caulopterae.Fragments of cladodes and leaves were collected and prepared in accordance with standard optical and scanning electron microscopy techniques. The morpho-anatomical characteristics found in B. glaziovii, include three-winged stems showing wings in a regular arrangement around the stem axis, short and petiolate leaves, flagelliform and simple non-glandular trichomes, concave-convex midrib, petioles with a concave shape and a slight projection on the adaxial face and convex with three projections on the abaxial surface, and calcium oxalate crystals in the form of raphides, styloids and pyramidal in the perimedullary region of the cladode, when evaluated as a whole, provide support for the quality control.
