'''''Zanthoxylum simulans''''', the '''Chinese-pepper''',<ref>{{PLANTS|id=ZASI2|taxon=Zanthoxylum simulans|access-date=9 August 2015}}</ref> '''Chinese prickly-ash''' or '''flatspine prickly-ash''', is a flowering plant in the family Rutaceae, native to southern and central China, Taiwan, and South Korea.<ref name = powo/> It is one of several species of ''Zanthoxylum'' from which Sichuan pepper is produced.
It is a spreading shrub or small tree growing to 7 m tall. The leaves are 7–12.5 cm long, pinnate, with 7–11 leaflets, the leaflets 3–5 cm long and 1.5–2 cm broad. There are numerous short (3–6 mm) spines on both the stems and the leaf petioles, and large (several cm) knobs on the branches.
