Tritonia are small bulbous plants up to 80 cm, that appear in great numbers in spring. The leaves are fan-shaped. The flowers are shades of yellow, orange or brown, sweet-smelling, and give off a very strong fragrance, especially at night. They are not grazed.[2]

The genus name is derived from the Latin word triton, meaning "weathervane", and alludes to the apparently random arrangement of the stamens in some species.[3]
