Matayba guianensis Aubl . is a shrubby or arborial Sapindaceae quite common in the Brazilian Cerrado with a key role in providing resources for ants and bees. It presents a rapid growth, and is important for the recovery of degraded areas, but little is known about its seedlings production. Therefore, the aim of this study was to describe the morphology of the branch and the seed germination and of seedling Matayba guianensis Aubl . in its post-seminal development and define the type of substrate and container suitable for seedling emergence and seedling production of this species. We evaluated three types of containers: black polyethylene bags, cartridge and polystyrene tray, with 5 kinds of substrates: sand, earth, earth - sand - manure (1:1:1); commercial substrate, and coconut fiber, with 4 replicates of 25 seeds per treatment . The branch, fruit, seed, seedling and their morphological events were described. The branch is cylindrical with paripinnate and alternate leaves, the fruit is dry and dehiscent. The seeds have a large amount of aryl, and the germination is cryptocotylar and hypogeal. The highest percentage of emergence occurred in styrofoam container with 91 % of the seeds germinated in commercial substrate , followed by coconut fiber (88 %). The development of root and stem were higher in tubes and plastic bags , using coconut fiber or commercial substrate.
