Anadenanthera colubrina

Anadenanthera colubrina (also known as vilca, huilco, huilca, wilco, willka, cebil, or angico) is a South American tree closely related to Yopo, or Anadenanthera peregrina. It grows from 5 m to 20 m tall and the trunk is very thorny. The leaves are mimosa-like, up to 30 cm in length and they fold up at night. In Chile, A. colubrina produces flowers from September to December and bean pods from September to July. In Brazil A. colubrina has been given "high priority" conservation status.
