Trifolium arvense

The QAs occurred in all the legume genera, species and sub-species studied. There were both QAs and QAs plants (Table 28). The frequency of QA occurrence mostly varied (0.1-0.8) between species (P< 0.001). The smallest frequency was found in only two species. Trifolium arvense and Trifolium pratense, in which positive test results were not found more frequently than every tenth individual (Table 28).

Those Haslam noted of Type (ii) include Vitis spp., Sorghum spp., and Vac-cinium oxycoccus. Further studies on the grape show that the leaves have a Type (i) polymer, and the Type (ii) are widespread in the Leguminosae - in Vida sativa, Lotus spp., Trifolium arvense, and Onobrychis vidifolia (36). Others include Vacdnium, Photinia spp, and Chaenomeles spedosa (L. J. Porter, unpublished results) and also apparently is almost the universal type in conifer barks (Pinus, Podocarpus, Pseudotsuga) (66, L. J. Porter, unpublished results).
