The flowers of Mesembryanthemum tortuosum may be white, pale yellow or pale pink. They have spindly narrow petals, spreading to a corolla width of 3 cm. The flower in picture has a pale yellow centre, the outer petal parts white.
The species used to be called Sceletium tortuosum, also in this Album; it sometimes still goes by that name. The plant grows in the arid inland parts of the winter rainfall region in the south-west of South Africa. This specimen was seen at the Minwater farm near Oudtshoorn (Vlok and Schutte-Vlok, 2010; iSpot).
