Description:

  • Large foetid shrubs with whitish bark; branches usually somewhat curved, brittle, ribbed by decurrent leaf bases when young, glandular-puberulous on uppermost parts
  • Leaves opposite and decussate, sometimes fascicled, lanceolate, acute; base tapering into petiole, subentire to serrate, base of petiole persistent, decurrent down stem in 2 narrow ridges, glandular-puberulous
  • Flowers pedicellate, 1-many in axils of leaves or bracts, forming a terminal thyrse
  • Calyx obscurely bilabiate, 5-lobed nearly to base, glandular-puberulous
  • Corolla bilabiate, 5-lobed, persistent; tube narrowly funnel-shaped or subcylindrical, mouth laterally compressed, elliptical, posterior side of tube with band of unicellular clavate hairs from mouth to base; posterior lip 2-lobed, exterior in bud; anterior 3-lobed; lobes spreading, suborbicular, glandular-puberulous outside, inside minutely glandular around mouth
  • Stamens 4, didynamous; posterior ones included, with filaments decurrent to base of tube; anterior ones arising in throat, exceeding posterior pair, very shortly exserted; anthers synthecate, dorsifixed, thecae transversely kidney-shaped
  • Nectary not conspicuous, possibly very shallowly annular
  • Ovary bilocular, deltoid, glabrous; ovules many per locule; stigma bifid, just reaching mouth
  • Fruit a septicidal capsule, each valve with a short loculicidal split at tip
