    Identification difficulty
    ID guidance

    Dense flat-topped corymbs; terminal lobe of leaf not much larger than lateral lobes (much larger in Marsh Ragwort); supplementary phyllaries (bracts under flower head) less than half as long as main ones.  Oxford Ragwort has looser corymbs and black-tipped phyllaries.  Hoary Ragwort has leaves with dense greyish cottony hairs underneath, narrow lobes and longer supplementary phyllaries (about half as long as main ones).   

    Phyllaries often stated to be black-tipped, but this is not a key characteristic.
