Rumphius's Cannabis: A Seventeenth-Century Naturalist and the Oldest Plant Dispersal Nobody Followed Up On
Zomia Collective Patreon· 2026
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.

Unraveling the Confusion of Flowering Types and Terminology in Cannabis sativa

Perspective/review arguing that cannabis “flowering” terminology is inconsistent across research and industry, which leads to misclassification of photoperiodic behavior and reproductive structures. Proposes clearer categories for female reproductive development (pistillate flowering) and distinguishes multiple male flowering expressions, with descriptive examples and photos to standardize usage across controlled-environment and field contexts.
