Flowers 12 to 20mm across with ray florets between 5 to 9mm long.

The phyllaries are fairly long and bend only slightly backwards at the top. [a concolourously green caterpillar wraps itself 1/3rd of the way around the green sepals, avoiding the yellow petals perhaps as camouflage]

The stems have short hairs. The upper leaves emerge just below each branch in the stem.

The upper leaves are narrow but with a central groove on one side and pinnate - with short branches coming off each leaflet.

The leaves are branched in a manner reminiscent of antlers.

The stems are short-hairy and with many grooves. A leaf peels off just beneath a junction of stems.The leaves are a darker shade of green than the paler-green stems (and it is not because of the hairs - they are the same on both).

Easily confused with : many other Ragworts and Groundsels - from both the (Senecio) and the Jacobaea species which are best differentiated from each other by the shapes of their leaves; a little less so by their flowers and phyllaries.

Not to be semantically confused with : Ragweed (Ambrosia artemisiifolia) [a plant with similar name in the same family, Asteraceae]

Uniquely identifiable characteristics

Distinguishing Feature : the short hairs on the stem and other parts.

No relation to : Flower () [plants with similar names belonging to differing families].
