Greater Burnet-saxifrage is a hairless perennial which grows to about 1 metre high on grassy roadsides and in woodland borders, mainly in the south-west and west of Ireland. It bears its small 3mm, white (occasionally pink) flowers in terminal umbels (3-6cm across) which have 10-25 rays. The flowers, which have no sepals, have long styles. There are no bracts or bracteoles below the umbels. The leaves are pinnate, glossy, and the oval-elliptical leaflets are toothed. The hairless stems are hollow and very strongly ridged. The fruit is egg-shaped with ridges. This species is in bloom in June and July and is a native plant.
I first came across this species in July, 2014, in Clonbur, Co Galway when I also photographed it.
