Abstract
Five spp. grown on 5 kinds of soil are considered. Statistical details are given for numerous measurements and counts. Records of flowering, seed production and germination, general tone, changes in habit and other characters are summarized. Centaurea nemoralis has proved a persistent perennial, showing little variation on the various soils. Silene vulgaris showed marked differences in its root systems on the different soils, but on none of them did its characters approximate to those of S. maritima which showed great fluctuation but was not a persistent sp. Anthyllis vul-neraria showed no morphological changes. It is a shortlived sp. in the absence of competition and grazing. Plantago major has proved extremely plastic. On clays the growth is luxuriant and the plants produce many crowns; on sands growth is poor, death rates are high, and crowns single or few. Details given show these and other differences due to edaphic factors. The effects of slug attack are considered. The experiments indicate clearly the very different reactions, or lack of reactions, of the spp. tested to different soils, and the complexity of a plant''s environment.
