Japanese pepper Zanthoxylum piperitum, photographed by Karl Gercens.

Belongs within: Rutaceae.
Contains: Boronieae.

The name ‘Zanthoxyleae’ is here being applied to a clade corresponding to the ‘Euodia alliance’ of Kubitzki et al (2011), as the Zanthoxyleae as previously recognised are paraphyletic with regard to other tribes within the Rutaceae. Members of the Euodia alliance are found mostly in the Old World, with only the genus Zanthoxylum present in the New World. Zanthoxylum is pantropical; the fruit of some species of this genus such as Z. piperitum are used to make Sichuan pepper. Species of Zanthoxylum are distinguised by flowers with a 1- to 5-loculed gynoecium, producing fruit of one to five distinct or basally connate follicles.

The Diosmeae are a southern African clade with connected ovarioles and exalbuminous seeds. Melicope is a genus of trees and shrubs found in tropical Asia and Australasia with 1- or 3-foliolate leaves and tetramerous flowers with minute sepals and inflexed apices to the petals (Allan 1961). Flindersia is an Australasian genus of trees bearing opposite leaves and fruits as five-valved capsules containing winged seeds. The Toddaliinae have petals that are imbricate in the bud, and carpels remain united until maturity to form a two- to seven-celled fruit. The white sapote Casimiroa edulis is cultivated for its edible fruit.

Characters (from Kubitzki et al. 2011): Mostly rainforest trees or shrubs; flowers mostly (5-)4-merous, diplo-(haplo-)stemonous; ovarioles distinct or basally connate and stylodia joined in a common style, or gynoecium syncarpous; ovules 2, 1, or rarely more than 2; fruits dehiscing or drupaceous; dorsilateral endocarp in dehiscent fruits usually discharged with seed; ventral endocarp sometimes well developed; seeds with or rarely without sclerotesta, sometimes with sarcotesta, albuminous or exalbuminous.
