Groundsel (Senecio vulgaris) is also widely naturalised in other parts of the world, including throughout most of North America (i.e. Groundsel is a 'weed' of cultivated and disturbed ground like field edges, roadside verges and waste ground. Senecio eboracensis was first recorded by R. J. Abbott and D. F. Marshall on wasteground in York, England, in 1979 , and was later demonstrated to be tetraploid (2n = 40) and highly fertile. Few herbicides are registered for common groundsel control in such crops, and understanding and predicting the timing and extent of common groundsel emergence might facilitate its management. In an investigation of two annual Senecio species (S. vernalis and S. vulgaris), Hartmann and Zimmer (1986) found that the highest PA content occurred in the capitula, and that PA concentration (1.0-1.4 mg/g fresh weight) was 5- to 10-fold higher than in the roots and leaves. Experimental research using Senecio began in the late 19 th century (Table 1) when Anna Bateson, sister of the geneticist, William Bateson, showed that progeny generated by crossing Senecio vulgaris plants were taller and produced more seed per capitulum than those generated by self‐fertilization, suggesting an heterotic effect (Bateson, 1888). 606 Eisner and Meinwald have shown how the alkaloids are sequestered, how the female checks the male suitor for alkaloids and how they are passed to the eggs via the sperm.

GENETIC RESPONSE TO SPATIAL VARIATIONS OF THE ENVIRONMENT BY RICHARD J. ABBOTT Botany Department, University of St. Andrews, Scotland (Received 16 June 1975) SUMMARY Variation within and between four populations of the highly plastic and ephemeral plant The study of ecological interactions both at the individual plant and at the population level between Senecio vulgaris (common groundsel) and the rust fungus Puccinia lagenophora has been a major focus of our research during the past 15 years.
