Share on X

A family of about 10 genera and 500 species distributed in the tropics and subtropics. No native species in Japan, though some are cultivated as ornamentals. Its phylogenetic position within the core eudicots has been long debated.

Key Characteristics

  • Petals 5, mostly yellow or white
  • Stamens numerous, sometimes fasciculate
  • Leaves large with parallel primary and secondary veins
  • Sepals persistent, enclosing the fruit
  • Woody plants (trees to shrubs) or climbers
