Hoary Ragwort - Jacobaea erucifolia
Medium to tall, grey downy plant, with a shortly creeping stock bearing terminal leaf rosettes. Stems erect, branched above the middle. Leaves pinnately lobed, the lower stalked and usually present at flowering time. Upper leaves with narrower lobes; all leaves with somewhat down rolled margins and grey-hairy, especially beneath. Phyllary bracts not black tipped. Flowerheads bright yellow 12 to 15 mm with 12 to 15 rays, borne in a narrow flat topped cluster.
Leaves with dense cottony grey hairs on the underside; terminal lobe of leaf narrow. Phyllaries (bracts) at the base of the flower-head are about half as long as the main phyllaries. Common ragwort has basal phyllaries less than half as long as the main ones, and the leaves as more or less glabrous underneath.
