Description: Pterodiscus luridus is a caudiciform plant similar in many parts to Pterodiscus aurantiacus. It has a stout tuberous stem base or caudex rising a few cm above the ground, and sending forth from its crown, on the approach of the wet season, a few herbaceous, succulent, leafy, flowering branches covered, like the leaves and flowers, with a powdery pruinose pubescence. The leaves are oblong, deeply scalloped, upper surface dark green, lower surface bluish. The trumpet-like flower are dirt yellowish with many red dots on the outside. The fruits is round and 4-winged. This member of the Pedaliaceae family was described by Joseph Dalton Hooker in 1869.
Derivation of specific name: 'luridus' (Latin), drab yellow, dirty brown, for the flower colour.
