The poaia or ipeca (Psychotria ipecacuanha (Brot.) Stokes.-Rubiaceae) although its farmacological and partner-economic value is each less frequent time in its habitat. The objective of this work was to carry through the comparative study of the morpho-anatomics aspects between the originary species of the Brazilian Amazônia and gotten in vitro submitted the different treatments of interception of solar radiation, aiming at, of this form, to give has supported the studies with preservation ends, culture, pharmacognostic/pharmacopeic validation and to extend the biotechnological knowledge of this species. The native species was gotten of breaks up of bush (phase vegetative) and used for micropropagation through the culture in vitro of fragments of internodais segments on way of culture Murashige & Skoog with the plant growth regulator BAP (2.0 mg/l growth). Plantlet was gotten that they had been transferred to house of vegetation per 2 years under two types of environment and three different treatments of interception of the solar radiation. The morpho-anatomic study was made, statistics analyzed. And is verified that the plants originated for biotechnological process and submitted to the different treatments present similar morphology to the native plant, however evidenced a bigger number of secondary roots, does not have significant difference between widths and lengths of leaves, length of roots, internodais, stipules, weight of roots and rhizomes. But, difference was observed statistics in the length of stem in relation to the native.
