Stemodiopsis

Perennial herbs or almost subshrubs, most parts densely and minutely white-pubescent; stems much branched, erect to ascending or procumbent; branches 4-angled, leafy. Leaves opposite, ovate, petiolate, acute, cuneate, serrate-dentate. Flowers small, axillary, solitary, bracteate; in a lax raceme; pedicels filiform, minutely bibracteolate, decurved in fruit. Bracts foliose. Calyx 5-partite; lobes +/- narrowly triangular, acute, subequal, pilose. Corolla tubular, bilabiate, subcampanulate, 5-lobed; tube cylindrical to somewhat dilated at mouth, sparsely pilose to subglabrous outside; upper lip shortly 2-lobed, exterior in bud; lobes triangular-ovate; lower lip somewhat larger, shortly 3-lobed, subcircular, with a distinct palate, minutely pubescent within. Stamens 4, perfect, didynamous, arising +/- halfway up corolla tube, included in upper lip; all filaments curved inwards but longer anterior ones also bent outwards at base; anthers bithecate; thecae ovoid, equal, confluent at apex, strongly divergent; staminode 1, filiform, arising near base of corolla tube, or 0. Ovary bilocular, narrowly conical, attenuate into slender style; ovules many. Fruit an ellipsoid-conical, shortly beaked, puberulous, septicidal capsule, turned downwards; valves coherent or connivent at apex after dehiscence. Seeds small, many, narrowly oblong, usually somewhat curved, longitudinally ribbed.
