Zanthoxylum Beecheyanum

Zanthoxylum (including genus Fagara) is a genus of about 250 species of deciduous and evergreen trees and shrubs in the family Rutaceae, native to warm temperate and subtropical areas worldwide. It is the type genus of the tribe Zanthoxyleae in the subfamily Rutoideae. Several of the species have yellow heartwood, to which their generic name alludes.^[3]

The fruit of several species is used to make the spice Sichuan pepper. They are also used as bonsai trees. Historically, the bark was used in traditional medicine.^[4] Common names include "prickly ash" and "Hercules club".
