Graderia[1] is a genus of plants in the family Orobanchaceae, which is native to Africa and Socotra.

[4] Graderia is a taxonomic anagram derived from the name of the confamilial genus Gerardia.

The latter name is a taxonomic patronym honoring the English botanist John Gerard.

[2] The solitary flowers appear in the axils, and have a five-lobed calyx and corolla.

The flower is tubular with four stamens, in pairs of unequal length.
