Description:

  • Perennial herbs or dwarf shrublets; stems leafy throughout, pubescent, hairs retrorse and minutely glandular
  • Leaves opposite below, alternate above, simple, variously elliptical and oblong to oblanceolate, often narrowed to petiole-like, sometimes half-clasping or connate base, usually toothed, thick or leathery, glandular-punctate, sometimes also with glandular and/or eglandular hairs; radical leaves sometimes present
  • Flowers in a terminal, cone-shaped, very congested head, nodding in flower, erect and elongated in fruit
  • Bracts broad, clearly distinct from leaves, adnate to pedicel, free from calyx
  • Calyx unequally 5-lobed, rarely 2 anterior lobes obsolete, split nearly or quite to base at least on anterior side, thin-textured
  • Corolla slightly bilabiate, glabrous, thick, leathery when dry; tube funnel-shaped; posterior lobes exterior in bud, lobes spreading, oblong to suborbicular, entire, margins pale, thin-textured
  • Stamens 4, didynamous, arising near top of corolla tube, 2 or 4 exserted; posterior filaments decurrent ± to base of tube; anthers synthecate, dorsifixed; staminodes 0
  • Nectary at base of ovary on posterior side
  • Ovary bilocular, ± oblong; ovules 7-many per locule; stigma lingulate, flattened, with 2 marginal bands of stigmatic papillae, exserted
  • Fruit a septicidal capsule with a short loculicidal split at tip of each valve, glabrous
  • Seeds angled by pressure, sinuously colliculate, reddish brown
  • x = 7
