This work studied the morphological and anatomical characteristics in young plants of Chorisia speciosa, cultivated under drained soil and flood conditions (control). The experiment was developed in a greenhouse, using plants with 90 days after the emergency, submitted under flood conditions by 30, 60 and 100 days. Sections in different planes of fresh and fixed roots, stems bases and leaves, were made using standard procedures in vegetal anatomy. After 30 days of flooding, hypertrophic lenticels can be observed in the stem base and in 60 days, adventitious roots, with cellular space on the cortex and absence of root hair. With 100 days appeared new leaves. The anatomical response by flooding on the radical principal system were: beginning of deterioration on the apical meristem after 60 days of stress; collapse of cells and cells with irregular shape in the cortex and pith, in 30, 60 days of experiment
