ABSTRACT
The wood anatomy of three species and one variety of genus Calycophyllum DC. (C. candidissimum, C. multiflorum, C. spruceanum e C. spruceanum f. brasiliensis) is presently described according to IAWA (1989). Most of the observed characteristics agree with the common pattern described to family Rubiaceae, and allows grouping them in the "Type II" wood structure: predominantly radial multiple pores; axial parenchyma absent; large rays (2-4 or more cells), with few layers of square and upright cells in the margins; septate fibers with simple pits. These characters, observed in all studied species, do not agree with the anatomical pattern referred to Ixoroideae subfamily.
