Description :

  • Small annual herbs; stems laxly leafy, often with axillary leaf tufts (incipient branches), glandular above, with retrorse, eglandular hairs below
  • Leaves opposite below, alternate above, mainly radical, elliptical, tapering into broad petiole or briefly narrowed to base (cauline leaves), entire to sparsely dentate, pubescent on upper surface, glabrous below
  • Flowers in a lax raceme, often panicled
  • Bracts adnate to pedicel and most of calyx tube, usually with coarse, patent eglandular hairs on margins
  • Calyx bilabiate, ± plicate at anthesis; lips short, posterior lip shortly 3-toothed; anterior lip scarcely lobed, membranous; lobes shorter than tube, midrib of each lobe thickened
  • Corolla tubular, bilabiate, 5-lobed, resupinate by curvature of upper part of tube; tube narrowly cylindrical below, widening towards throat; posterior lip 4-lobed, exterior in bud, inclining downwards, bearded with clavate hairs at base and down back of throat; anterior lip entire, erect
  • Stamens 2 (posterior pair); filaments decurrent to base of tube forming a channel enveloping style; anthers synthecate, dorsifixed, well exserted, connective glandular; staminodes 2, small
  • Nectary small, completely adnate to base of ovary on one side
  • Ovary bilocular, oblong-elliptical, glandular or not on sutures; ovules many (more than 20 per locule); style passing gradually into lingulate stigma with two marginal bands of stigmatic papillae, exserted
  • Fruit a septicidal capsule with a short loculicidal split at tip of each apiculate valve
