          Abstract

          As plantas de Uncaria guianensis e U. tomentosa são lianas trepadeiras, arbustos trepadores ou rasteiros ascendentes que ocorrem em amplas áreas da Amazônia brasileira e países da América Central e do Sul. Possuem excepcional importância medicinal, com sua casca, lenho e folhas utilizadas pelos povos amazônicos e pela indústria farmacêutica. Face a necessidade da identificação das plantas em condições de campo e de laboratório, o presente trabalho descreveu a estrutura anatômica do lenho de Uncaria guianensis e U. tomentosa, ocorrentes no Estado do Acre, Brasil. Os resultados mostraram que o lenho das espécies é característico da família Rubiaceae, a exceção dos vasos arredondados, grandes e solitários, parenquima axial difuso e largura dos raios que são próprios das lianas.
