Sea Spurge could sometimes be confused with:

Spurge, Portland,

On coastal sands, dunes, shingle and beaches, this perennial grows to a height of 50cm, higher than its close cousin, Portland Spurge.  Its flowers are arranged in umbel-like clusters, mostly 3-6, with horned glands at their rims.  They flower from June to late October.  The waxy, oval leaves of this plant are grey-green, and hairless, with the midrib not being prominent as in Euphorbia portlandica. The plant, being fleshy, withstands the coastal conditions extremely well.  This is a native plant and belongs to the family Euphorbiaceae.

I first identified this plant at Kilcoole, Co Wicklow in 1978 and photographed it at Bishops Quarter, Co Clare in 2006.
