Plants from five species of Pedicularis (Scrophularia-ceae) take up alkaloids from their host plants. Those of Pedicularis groenlandica and P. bracteosa take up senecionine (5) from the host Senecio triangularis. Those of Pedicularis crenulata contain anagyrine (Fig. 30.1) (a quinolizidine alkaloid) from the host Thermopsis divaricarpa. Plants of Pedicularis racemosa contain quinolizidine alkaloids from a Lupinus argenteus hybrid (Schneider and Stermitz, 1990).
