Gloriosa rigidifolia

Gloriosa rigidifolia, commonly known as the butter lily, in Afrikaans as geelklokkies (little yellow bells) and previously scientifically as Littonia rigidifolia, is a cormous perennial.

The erect stems are leafy from the base. The opposite, stalkless leaves ascend from the stems. They are narrow, nearly linear, tapering to acutely pointed, tendril-like tips that curl down strongly in an O-shape. As the specific name suggests the blades are rigid, also bright green to dark green, hairless, glossy and channelled above, the margins sometimes rolled under.

The species distribution of this South African endemic is limited to a region in the southwest of Limpopo in the Waterberg.

The habitat is subtropical, summer rainfall rocky grassland and bushveld. The habitat population is deemed of least concern early in the twenty first century (Leistner, (Ed.), 2000; Letty, 1962; iNaturalist; https://powo.science.kew.org; http://redlist.sanbi.org).
