This is one of those many yellow ‘Dandelion-like’ species which are not easy to identify. However, the covering of rough, white hairs makes it a little different to some of the other members of the Asteraceae family. The golden yellow flowers (25-30mm across) are ligulate, that is they consist of only ray florets, each of which terminates in a 5-toothed tip. These florets are longer than the involucre of bracts beneath the flowerhead. The flowers are borne solitarily on unbranched, erect, leafless stems which arise from a basal rosette of coarse wavy-toothed leaves. A few tiny scales may occur on the stem (see bottom image). This species grows to about 40cm tall.
I first saw and photographed this species in Pollardstown Fen, Co Kildare in 2015. I was with Jackie O’Connell and Paul Green and might not have been able to identify it readily but for their help.
