SANBI Flora Keys Logo
Interactive keys to the identification of seed plants of southern Africa using keys based on plant morphology.
Backtrack a
  • Flowers 5-merous
 002
b
  • Flowers 4-merous (rarely 5-merous)
 002
Backtrack a
  • Corolla choripetalous (but the petals connivent and superficially sympetalous), buds and open flowers strongly curved or bow-shaped
 Plicosepalus
b
  • Corolla sympetalous, forming at least a short, but more often a conspicuous basal tube, essentially straight above the often swollen base
 002
Backtrack a
  • Flowers bilaterally symmetrical following anthesis (bearing a single V-shaped unilateral split which is sometimes obscured in pressed specimens)
 002
b
  • Flowers radially symmetrical following anthesis (not producing a V-shaped split)
 002
Backtrack a
  • Filaments following anthesis essentially erect but often curving slightly inward, ± 3 mm long
  • Styles conspicuously tomentose in lower half
 Vanwykia
b
  • Filaments following anthesis coiled or inflexed 90º or more, 5 mm or longer
  • Styles essentially glabrous
 002
Backtrack a
  • Style gradually thickened from above the middle and abruptly constricted into a conspicuous neck below the enlarged and rounded stigma (skittle-shaped)
 002
b
  • Style with essentially the same diameter throughout its length (filiform)
 002
Backtrack a
  • Corolla lobes conspicuously reflexed
 Tapinanthus
b
  • Corolla lobes erect
 002
Backtrack a
  • Corolla glabrous or shortly hairy, not stellate or dendritic
 Agelanthus
b
  • Corolla densely covered with stellate or dendritic hairs
 Phragmanthera
Backtrack a
  • Corolla lobes distal from point of filament attachment, usually much shorter or occasionally as long as the rest of the corolla
  • Corolla tube below split (i.e. closed portion) ± 10 mm or longer
 002
b
  • Corolla lobes distal from point of filament attachment, at least twice the length of the rest of the corolla
  • Corolla tube below split (i.e. closed portion) ± 7 mm long or less
 002
Backtrack a
  • Corolla tube without conspicuous basal swelling, if slightly expanded basally, then never abruptly constricted, enlarging laterally to at least 3 mm or more in diameter
 Agelanthus
b
  • Corolla tube with conspicuous basal swelling, then abruptly and very narrowly constricted (± 0.5mm) just above swelling, thereafter, enlarging laterally to ± 1.5 mm
 Oncocalyx
Backtrack a
  • Corolla reddish orange (mature buds black-tipped), lobes reflexed into coils
  • Anthers typically breaking from filaments at anthesis
  • Inflorescence primarily umbellate, but occasionally an apically crowded raceme
 Moquiniella
b
  • Corolla greenish yellow, lobes erect to slightly reflexed, never coiled
  • Anthers mostly persistent following anthesis
  • Inflorescence umbellate
 Oncocalyx
Backtrack a
  • Corolla bearing conspicuously long (3-5 mm), white, silky, ascending hairs
  • Young leaves generally light to densely stellate-pubescent
  • Inflorescence a head
  • Anthers typically breaking from filaments at anthesis
 Erianthemum
b
  • Corolla, leaves, and inflorescence esentially glabrous
  • Inflorescence umbellate
  • Anthers mostly persistent following anthesis
 002
Backtrack a
  • Corolla lobe inrolled at anthesis
 Oliverella
b
  • Corolla lobe strongly reflexed at anthesis
 002
Backtrack a
  • Filaments curving gently outward to 90º following anthesis, essentially isodiametric
  • Style broadly recurved ± 180º near apex
  • Corolla tube expanding slightly upward, 35-40 mm long, 3-5 mm wide, greenish yellow
 Pedistylis
b
  • Filaments tightly coiled following anthesis, coiled portion distinctly thicker and wider than rest of filament
  • Corolla tube 15-20 mm long, 1-2 mm wide, crimson and yellow
 Actinanthella
Backtrack a
  • Inflorescence a raceme or spike
  • Corolla choripetalous (but petals connivent and superficially sympetalous), glabrous, radially symmetrical
 Helixanthera
b
  • Inflorescence a single to few-flowered, sessile umbel
  • Corolla canescent or tomentose, sympetalous, bilaterally symmetrical (bearing a unilateral V-shaped split)
 Septulina
