Gloriosa rigidifolia, commonly known as the butter lily or geelklokkies (little yellow bells) in Afrikaans 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. The rigid blades are 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.

The habitat is subtropical, summer rainfall rocky grassland and bushveld. The species is not considered to be threatened in its habitat early in the twenty first century (Leistner, (Ed.), 2000; iNaturalist; https://powo.science.kew.org; http://redlist.sanbi.org).
