Tridentea

Tridentea is a genus of succulent plant in the family Apocynaceae, endemic to southern Africa.

It was subsequently split, and the genus Tromotriche was created for the ten species which were separated.

Tridentea stems are typically smooth, soft and appear as roughly four-edged in cross section.

In young growth, each tubercle bears a small splayed leaf-remnant.

Tridentea flowers are flattened, star-shaped, and usually brightly coloured.
