A scheme is presented which outlines the possible mode of biogenesis of alkaloids
so far reported from the proteaceous plants Bellendena montana and Agastachys odorata (both from Tasmania), Darlingia darlingiana and D. ferruginea (from Queensland) and Knightia deplanchei and K. strobilina (from New Caledonia).
