This study treats some structural aspects of a population of Callisthene fasciculata (Spr.) Mart. growing on a ridge in the Pantanal of Poconé, in Mato Grosso State, Brazil. The project was carried out in 1ha of cerradão (savanna forest) at Fazenda Retiro Campo Largo, Poconé. Callisthene fasciculata is a common species in the cerradão. Formations of C. fasciculata, regionally denominated `carvoeiro' and/or `carvoal', occur frequently. This species is of economic importance because of its use for fence posts, charcoal and firewood. Data on its population structure were analysed and are presented based on the circumference class categories at breast height (cbh) and variation in height. The 869 individual trees in the sample hectare included 17 families and 33 species, and were dominated by the 229 individuals of C. fasciculata.
