One could describe this species as a “Big brother” of the earlier discussed Ruschia grisea. It is a robust shrub to 70 cm tall with ascending branches. The leaf-pairs are fused to each other below, with the free parts usually shorter than the basal leaf sheath; the keel is decorated with a single indistinct tooth.
In late spring/early summer (Oct.-Jan.) the plants are blooming with white flowers 22 mm in diam.
The species is to be found on shale and gravel plains of the southern Great Karoo from Matjiesfontein to Prince Albert.
