Senecio mandraliscae, also known as blue straws, blue chalksticks, dassieharpuis, or narrow-leaf chalk sticks, is a succulent plant of the family Asteraceae that is native to South Africa.

The leaves are linear, rising, sickle shaped and would be narrow at both ends.

Unlike the similar looking Curio repens, its leaves are much narrower and elongated.

[4] Curio repens is also easily distinguished by its shorter, often boat-shaped leaves.

[5] It is also easily confused with Curio ficoides, which has a similar growth habit.
