Guazuma ulmifolia Lam. is pioneer species of natural occurrence in different regions in Brazil. It belongs to the Sterculiaceae family and is indicated for recovery-degraded areas. The objective of this research was to describe and illustrate the morphological aspects of the fruits, seeds, seedlings and juvenile plants. For the study of the fruit, the following aspects were observed: type, color, dimensions, texture, opening and number of seeds per fruit. For the seed the color, weight of 1000 seeds, form, tegument, embryo and endosperm were observed. The seedling stage was considered while it has only cotyledons, the saplings stage was considered after the appearance of the first leaf. The vegetative aspects described and illustrated were: primary, secondary and tertiary roots, hypocotyl, cotyledons, stem, leaf and apical bud. The fruit is a globose loculicidal capsule, with dark coloration, narrow stripes and surface muricate. Gray-colored seeds, varied shapes, wrapped by the testa and if humid becomes gelatinous. Axile embryo e and continuous; with foliaceous cotyledons, folded and after emergence they are round, green colored with ribs. After emergence the hypocotyl and primary root are white and cylindrical, but after some time they become darker. Stem is dark-green in color; petiolated leaf, with main and secondary ribs, limb with dentate edge.
