Distribution in the Neotropics

Nine genera and about 35 species worldwide, mostly being found in temperate to subtropical Asia. Two monoytypic genera in the Neotropics, C & S. Chile and W. Argentina, often occurring in humid forests on riverbanks:

  • Lardizabala Ruiz & Pav. - One species native to temperate forests of C. & S. Chile and Juan Fernandez Islands.
  • Boquila Decne.- One species native to temperate forests of C. & S. Chile, and W. Argentina.
Diagnostic
Distinguishing characters (always present)
  • Evergreenwoody vine.
  • Compound leaves: Triternate or trifoliate.
  • Drooping racemose or cymose inflorescences.
  • Petioles and petiolules swollen at both ends.
Key differences from similar families
  • Smilacaceae- Rhizomatous; tendrils present; inflorescences umbellate.
  • Dioscoraceae- Leaves campylodromous; ovary inferior; fruit a dry capsule; seeds winged.
Useful tips for generic identification
  • Boquila flowers are white, Lardizibala are dark purple.
  • Boquila sepals membranous, fleshy in Lardizibala .
  • Lardizabala fruit is many seeded, few to one seed in Boquila
General Description
Status
  • Native.
General notes

Berries of Lardizibala biternata and Boquila trifoliolata are edible.
