More
Perennial herb or suffrutex, parasite, 0.08-0.65 m high; stem erect, herbaceous when young, branched at base, pilose. Leaves 10-22(-30) x 4-17 mm, subsessile, opposite or alternate, lanceolate, margins incised-pinnatifid with acute teeth; nerves prominent beneath. Inflorescence a raceme; flowers pink, in axils of upper leaves, shortly pedicellate, bibracteolate. Calyx 7-10 mm long, campanulate, hispid; lobes triangular-lanceolate. Corolla funnel-shaped; tube pubescent; lobes broadly rounded, spreading. Stamens: filaments filiform, pilose; anthers glabrous. Ovary somewhat gibbous; style filiform, persist in young fruits. Flowering time Aug.-Mar.
Leaves opposite or nearly so or alternate, 10–22(30) x 4–17 mm., ovate elliptic or more usually lanceolate, acute, subcuneate to subsessile at base, margins incised-pinnatifid with acute teeth or rarely subentire, scabrid-hispid, 3–5-nerved with nervation prominent beneath.
Erect, ascending or rarely procumbent perennial suffrutex, 7–30 cm. tall, from a woody rootstock, usually branched at or near the base; stems obtusely quadrangular above, indumentum of large multicellular pilose hairs, leafy, slightly herbaceous (at least when young).
