Heteropsis melinonii (Engl.) A.M.E.Jonker & Jonker

• Genus: Heteropsis
• Botanical Background: First described by Engler and later revised by A.M.E. Jonker & Jonker, Heteropsis melinonii has a well-documented botanical history. Its study has been enriched by contributions from renowned institutions such as the Missouri Botanical Gardens and the International Aroid Society.

• Geographical Range: Indigenous to tropical rainforests where high humidity and steady rainfall define the landscape. Its distribution is typically associated with lowland to mid-elevation forested regions.
• Environment: Thrives in warm, humid climates with rich, well-draining soils. It favors shaded understory conditions, where filtered light and consistent moisture support its growth.

Leaves

• Large, ovate to elliptical leaves
• Glossy texture and subtle variegation
• Leaf size and shape can vary depending on its microhabitat
