MONOCOTYLEDON - LILIIDAE - ASPARAGALES - Anthericaceae

Compiled by N.L. Meyer

Description :

  • Perennial herbs with erect, largely leafless aerial stem bearing terminal inflorescence; rhizomes not yellowish inside
  • Leaves in a basal rosette, spirally arranged or distichous; erect, flat and dorsiventral, sometimes terete or triangular, linear, sheathing at base; inconspicuously parallel-veined, rarely scleromorphic, rigid or succulent; oxalate raphides widely found
  • Inflorescences simple or compound racemes, or panicles, sometimes condensed into heads or clusters
  • Flowers bisexual, usually regular, rarely irregular ( Chlorophytum ), hypogynous
  • Perianth 3 + 3, free or basally connate into a tube, colours varying from white to blue or violet
  • Stamens 3 + 3; filaments free, glabrous; anthers dorsifixed-epipeltate, or basifixed, introrse, opening longitudinally; microsporogenesis usually successive; pollen sulcate
  • Ovary superior, 3-locular; placentas axile; ovules 2-many; style 1 with a small stigma
  • Fruit a loculicidal capsule
  • Seeds elongate, ovoid and often angled, black or white

Classification Notes:

  • Steroidal saponins mostly present, but anthraquinones (which are always present in the closely related Asphodelaceae , and displayed especially by the rhizomes which are yellowish when cut) absent. Cyanogenic compounds are known in Chlorophytum. Caesia R.Br. is sometimes placed in Hemerocallidaceae
