Resumo: 	The geographical distribution and morpho-genetic variation of wild and domesticated populations of a crop species are essential information for identifying a center of origin. The pejibaye (Bactris gasipaes Kunth) is the only domesticated neotropical palm, whose starchy-oily fruits are subsistence products and whose heart-of-palm is an expanding agribusiness. The origin of pejibaye is unresolved, but probably will be found in the distribution of type 1 B. gasipaes var. chichagui in southwestern Amazonia. A new area of occurrence of this type is reported around São Felix do Xingu, Pará, Brazil, 52°41' W 6°34' S, about 600 km northeast of the eastern-most known population, in central Mato Grosso, Brazil. The plants of this population are slightly less robust than other type 1 plants and have small fruit bunches (60-70 fruit), small fruit (0.45 g and 10 by 9 mm) and seed (0.23 g and 6.5 by 7.4 mm), all smaller than previous descriptions. Although this find is disjunct from earlier reports, it is unlikely that other populations are absent between it and central Mato Grosso, expanding type 1 var. chichagui's distribution by 30% and redefining it as a typical element of the transition between humid and semi-humid forests across southern Amazonia, rather than an Andean element expanding into the region.
