Heteropsis duckeana M.L.Soares

• Genus: Heteropsis
• Botanical Background: Described by M.L.Soares, the species draws historical significance from studies of tropical aroids. Its naming honors botanist Adolpho Ducke, whose extensive work in Amazonian botany laid the foundation for modern tropical plant taxonomy.

• Geographical Range: Indigenous to the Brazilian Amazon, where it forms part of the diverse understory flora in tropical rainforests.
• Environment: Warm, humid conditions with high rainfall. It favors well-drained, organic soils typical of forest floors, where dappled sunlight and consistent moisture support its growth.
