Zamia brasiliensis is a cycad from the transition zone between Cerrado savanna and Amazon forest in Brazil, grown as a slow-growing, palm-like foliage plant. Like all cycads it grows slowly and needs bright light, good drainage, and protection from frost.

About
Zamia brasiliensis is a species of plant in the family Zamiaceae, found in Mato Grosso and Rondônia states in Brazil. It is morphologically similar to Z. boliviana and Z. ulei, which are found in ranges that are adjacent to, but do not overlap, that of Z. brasiliensis, in the Amazon basin. It is found in several locations across its range, but is threatened by widespread clearances of forest being converted to cattle pastures.
Where it grows
Zamia brasiliensis grows in equatorial savanna with dry winter. Strobili (cones) develop from September to December, with pollination occurring from October to December. Seeds are released from June through September. New leaves emerge from August to November. An unidentified species of beetle in the genus Pharaxonotha, a potential pollinator, was identified as living with one population of Z. brasiliensis. In another population, larvae of a butterfly in the genus Eumaeus were feeding on the leaves of Z. brasiliensis. The species grows in the transition zone between the Brazilian Cerrado and the Amazon rainforest in upland areas of Mato Grosso and Rondônia states in Brazil. Specific habitats include dense and open ombrophilous forests, semideciduous and deciduous forests, and woodland savannas.
