Accession Data:

Trochodendron aralioides Siebold & Zucc.

  • Common Name: Wheel Tree
  • Family: Trochodendraceae Prantl.

  • Country of Origin: mountains of Japan & s. Korea
  • Habitat: Broad-leaved evergreen forests; 300-2700m

  • Description: Trochodendron aralioides is an evergreen tree or large shrub growing to 20 m tall. Trochodendron and Tetracentron lack vessel elements in their wood, a quite unusual feature in angiosperms. This has long been considered a very primitive character, resulting in the classification of these two genera in a basal position in the angiosperms; however, genetic research by the Angiosperm Phylogeny Group has shown it to be in a less basal position (early in the eudicots), suggesting the absence of vessel elements in these two genera is a secondarily evolved character, not a primitive one.2
