The false plum anemone is a large anemone of up to 20 cm in diameter. It has a smooth column that may be orange, yellow or red. The tips of its tentacles are often mauve. It has a protruding round mouth, and the oral surface may be striped. It has rows of small round protrusions (spherules) outside its tentacles.
It is found around the southern African coast from Luderitz to Durban. It is also found around Madeira. It inhabits waters from the intertidal to 35m in depth.
