Ceratotheca

Ceratotheca is a genus of flowering plants in the family Pedaliaceae. This genus is native to Africa, with most species found in southern Africa. The name "Ceratotheca" is derived from Greek words meaning "horn capsule," referring to the shape of the fruit. Plants in this genus are typically herbaceous annuals or perennials. They are characterized by their opposite or alternate leaves, which can be simple or lobed. The flowers are often showy, with a tubular or bell-shaped corolla, and can be white, pink, or purple. The fruit is a capsule, often with spines or horns.

Species within Ceratotheca are known for their medicinal properties and are used in traditional African medicine for various ailments. Some species are also cultivated as ornamental plants due to their attractive flowers. The genus is closely related to Sesamum, the genus that includes sesame. Ecological roles include providing nectar for pollinators and serving as food for some herbivores. Further research is ongoing to fully understand the taxonomy and ethnobotany of the genus Ceratotheca.
