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".[1]
There are approximately 79 species, mostly native to southern Africa, but with four species reaching tropical Africa. All except one grow from corms.[2]
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. http://pza.sanbi.org/hesperantha-coccinea
