Hesperantha is a genus of cormous flowering plants in the family Iridaceae.

The genus name is derived from the Greek words hesperos, meaning "evening", and anthos, meaning "flower".

[2] There are approximately 79 species, mostly native to southern Africa, but with four species reaching tropical Africa.

[1][citation needed] The synonym Schizostylis is widely used in British horticulture for the single rhizomatous species S. coccinea, widely cultivated as a garden flower, and with numerous cultivars.

[3] Common names include scarlet river lily, kaffir lily and crimson flag.
