npaliurusA genus of shrubs of the order Rhamneæ, the buckthorn family, and the tribe Zizypheœ, characterized by the dry hemispherical fruit, expanded above into an orbicular wing. There are two species, one of the Mediterranean region, the other of southern China. They are thorny erect or prostrate shrubs, bearing three-nerved alternate ovate or heart-shaped leaves in two ranks, and small flowers clustered in the axils. They are ornamental as shrubbery, and may be used as hedge-plants. P. australis (P. aculeatus) is one of the Christ's-thorns (sharing the name with Zizyphus Spina-Christi). See Christ's-thorn.
In the materials employed, hawthorn-and paliurus-leaves predominate.
