Resumo
Aiming to describe seedlings' morphology and cotyledons and eophylls anatomy of Gomphrena elegans Mart., 100 seeds were put into plastic bags, with sand and fertilized soil (1:3), kept in the greenhouse under room conditions, with 50% shady and watered daily. Cotyledonous petiole and limb and seedlings eophylls were sectioned in median and border. They were then analyzed in transversal and paradermic sections. Seedlings initial morphology is epigeal-foliar, the root is axial, and hypocotyls and epicotyl are reddish. Venation is of pinnate type, camptodrome and brochidrodome in cotyledons and eophylls. Petiole and leaf show uniseriated epidermis with cells of varied sizes and anomocytic stomata. Druses of calcium oxalate occurred in leaves and petiole. Dorsiventral mesophyll shows one palisade parenchyma layer and several lacunary ones.
