Analysis of Chapter XXXIV of Rumphius's Herbarium Amboinense (1747), the earliest known ethnobotanical account of cannabis in eastern Indonesia. Argues that Rumphius's description of Ginji Papoua — a morphologically distinct cannabis variety from the Papuan and Sula Islands documented in the 1690s — represents evidence of a pre-modern Austronesian cannabis dispersal route overlooked by the literature. Connects Madagascan pollen data, Austronesian maritime archaeology and Australian Bastard Cannabis morphology to propose a research agenda for eastern Indonesian landrace fieldwork.
