General Description
Notes on delimitation
  • Often formerly placed in Rhizophoraceae but differs in the spirally arranged exstipulate leaves and distinct styles and in the petals not aristate.
  • Now placed in the Cucurbitales by the Angiosperm Phylogeny Group near to Begoniaceae.
Status
  • Native
  • Polygonanthus endemic to Brazilian Amazonia
  • Anisophyllea also occurs in the Old World
Distribution
Distribution in the Neotropics
  • Pantropical with four genera, two of which are Neotropical.
Diagnostic
Distinguishing characters (always present)

Few defining characters:

  • Leaves often drying yellowish and often asymmetrical at base
  • Palmatevenation
  • Clawed or lacinate petals in Anisophyllea
  • Winged samara in Polygonanthus
Useful tips for generic identification
