Bucephalandra danumensis S.Y.Wong, P.C.Boyce & Kartini

• Genus: Bucephalandra
• Botanical Background: Described by botanists S.Y. Wong, P.C. Boyce, and Kartini, who documented it after extensive fieldwork in the Danum Valley. The species' description emphasizes its distinct leaf morphology and habitat specificity.

• Geographical Range: Native to the tropical rainforests of Borneo, specifically in the Danum Valley Conservation Area, it is found primarily at low altitudes near riverbanks, where it enjoys the rich, humid environment.
• Environment: Thrives in consistently humid, shaded environments. It requires high humidity levels and well-drained soil. The climate is tropical, with warm temperatures and frequent rainfall.
