Iridaceae - Ixioideae - Freesia Klatt

Description:

  • Deciduous perennials
  • Rootstock an obconic corm rooting from below, basal in origin, tunics finely to coarsely fibrous
  • Stem aerial, erect, or prostrate below, simple or branched, terete or compressed and angled
  • Leaves several, lower 2 or 3 cataphylls; foliage leaves unifacial, with a distinct midrib, in a distichous fan, blades plane, firm or soft-textured, sometimes prostrate
  • Inflorescence a spike, flexed at base, flowers borne on upper side; bracts green and soft-textured or coriaceous, often brown at apices, inner shorter than outer, notched apically
  • Flowers zygomorphic, hypocrateriform or narrowly to widely funnel-shaped, shades of white to yellow or pink to red, rarely greenish to brown, sometimes with contrasting darker markings on lower 3 tepals, usually strongly and sweetly scented, nectar, when produced, from septal nectaries; perianth tube either slender and cylindric throughout or narrow below, widened into a narrowly or broadly flared upper part
  • Tepals subequal or dorsal larger and hooded
  • Stamens unilateral and arcuate; filaments arising at base of wide part of tube; anthers included or exserted; pollen monosulcate, operculate, exine perforate
  • Style filiform, branches deeply divided and recurved
  • Capsules ± globose, coriaceous, usually papillate to rugose
  • Seeds globose, hard, shiny, smooth or rugulose, raphe inflated, flattened or concave at chalazal end, surface laevigate
  • x = 11

Classification Notes:

  • The genus is probably allied to Tritonia and Crocosmia

Nomenclature:

  • Freesia Klatt
    • Klatt: 672 (1866) name conserved
    • Goldblatt: 55 (1982)
    • Goldblatt & Manning: 161 (1995)
  • Anomatheca Ker Gawl.
    • Ker Gawler: 227 (1804)
    • Goldblatt: 75 (1972)

Distribution & Notes:

  • Global: Species 14, mainly in the southern Africa. winter-rainfall region, 2 species in E South Africa and south tropical Africa, 1 extending to Sudan
  • Southern Africa:
    • Most common in clay soils in renosterveld or karroid scrub
    • The 2 species of the summer-rainfall region occur in light shade in woodland or forest margins

Additional Notes:

  • The often highly scented flowers are mostly pollinated by bees, while the narrow-tubed unscented species are visited by butterflies and possibly moths
