Description:
Perennial herbs with a woody base, with branches usually terete, to 20 cm long, much-branched, densely covered with long spreading hairs and without sessile glands; leaves sessile, linear to linear-oblanceolate, 1-3 x 0.3-0.5 cm, obtuse, entire to pinnately lobed at the apex, with recurved margins, with long forward-directed hairs denser on the undersurface.
Inflorescence a thyrse without a distinct peduncle, branched or unbranched, with sessile cymose part-inflorescences reduced to 1 or 2 flowers in the axils of the leaf-like bracts, with internodes between pairs of part-inflorescences scarcely elongated; sepals regularly connate to about two-thirds of their length, with a posterior lobe often shorter, faintly veined, 3.5-5.5 mm long, acute, densely covered with spreading hairs mainly along the veins on the outside and the margins; corolla purple, pink or yellow, 1-lipped with 2 oblong lateral lobes and the spathulate anterior one with an emarginate apex, with short spreading hairs on the outside and a ring of short hairs where the stamens are inserted on the inside; stamens inserted below the throat of the corolla tube, with filaments glabrous; anthers with 2 diverging cells, exserted; ovary on a thick disc, scarcely 4-lobed, with a slender style inserted at about the middle, with a scarcely 2-lobed stigma.
Mericarps narrowly oblong-obovoid, 3-4 mm long, not keeled, with an attachment scar being a concavity 2-2.5 mm long with a raised ridge around it, reticulate-rugose.
