Abstract


In this paper described the anatomical distribution of laticifers from the bark of Hura crepitans
and Ficus maxima, typical floodplain trees in the Amazon forest. By observing samples which were
processed by usual plant anatomy techniques, it was possible to verify that there were laticifers
presenting radial distribution in the secondary stem phloem of F. maxima, and a diffuse distribution
in the axial phloem in H. crepitans.
