Mesembryanthemum tortuosum is a sprawling succulent herb growing to 30 cm in height from an underground caudex. Its slender, trailing branches may become 20 cm long. The plant often grows in the shade of taller plants in habitat, as the one in picture is doing.
The pale green leaves are keeled on the outside, concave on the inside and thickly fleshy with succulence. They are mostly carried in erect positions on the plant. Leaf shape is ovate with an acutely pointed tip. They become 4 cm long and 1 cm wide, growing in opposite pairs.
Some dried old leaf husks are still remaining on the plant in the photo from the previous season.
The plant is browsed by livestock and game (Vlok and Schutte-Vlok, 2010; iSpot).
