Zanthoxylum motuoense

A small deciduous tree, up to 15 meters; describable; thick branches, thorns often grow on the side of leaf scars, about 1 mm long, thickened at the base and presents a cushion. Single leaflet or leaf with 3 or 5 leaflets; leaflet broadly obovate or broad-elliptic, 3-6 cm long and 2-4 cm wide, the largest in the center, 9 cm long, 6 cm wide, and the ends are often close to round, rarely sharp or wedge-shaped, with finely cracked teeth on the edge of the leaf.[8] Except for oil spots located at tooth gaps, other oil spots are not obvious. Both sides are pubescent, and the hairs on the back of the leaf are dense and long; the leaf shaft has no wings. There are no thorns and a dense coat. The inflorescence is drawn out at the same time as the new leaves. The infructescence is conical, 4-8 cm long, with short hairs on the peduncle; the fruit petals are oval, about 4.5 mm in diameter, and the oil spots on the pericarp are large and slightly convex; the seed diameter is about 4 mm. The fruiting period is from September to October and is seen in the mountain forests of 1100 meters above sea level.[2][3][7]
