A small, erect, branching shrub (20-80 cm in height) with rounded, yellow-green leaves that have sharp, red-brown, cartilagenous margins.
The leaf tip is typically rounded or obtuse.

The succulent leaves are flattened, and ob-lanceolate or knife-shaped ("cultrata").
This shape, and the sharp, cartilagenous edges of its leaves, are distinctive.
 
In December/January it produces elongated flower stems (12-40 cm), each with several loosely-held clumps of yellowish flowers (one of which is terminal).
Each flower has black anthers and 3,5-4,5 mm long, cream coloured petals.
The loose arrangement of the flowers is a key diagnostic character of this species.
