Zanthoxylum dissitum is a woody plant native to China. It grows in upland thickets and open forests, forests, at 300-2600 m altitude [1][2] [3].[4]
The plant is a woody Climbing vine; and its stems turn gray-white when old. The brownish red thorns on the branches are strong and straight, or hooked downward on the leaf shafts and midribs. The leaf has usually 5-9 leaflets, or seldom three; leaflets are alternate or nearly opposite, with various shapes, up to 20 cm in length, 1-8 cm in width or wider, with cracked teeth on the whole or on the edge of the leaf (Zanthoxylum bungeanum). The leaves are symmetrical on both sides, the thin side is slightly slanted, the top is tapered to a long tail, thick paper or nearly leathery, hairless, the midrib is sunken on the leaf surface, the oil spot is very small, and it is not easy to see under the enlarged lens; The petiole is 3-10 mm long. The inflorescences are axillary, usually no more than 10 cm long, with short hairs on the rachis; 4 sepals and petals, with no oil spots; purple-green sepals, broad ovate, less than 1 mm long; petals light yellow-green, broad ovate, The length of the male flower is 4-5 mm; the pedicel of the male flower is 1-3 mm long; the stamens are 4, and the filaments are 5-6 mm long; the top of the staminodes is 4 lobed; the female flowers have no staminodes. The fruit is densely packed in the infructescence, with short fruit stalks; the fruit is brown, the exocarp is wider than the endocarp, the exocarp is smooth, and the edge is thinner. After drying, it shows an arc-shaped ring, 10-15 mm long, and the remaining style is on one side, long No more than 1/3 mm; seed diameter 8-10 mm. The fruit petals are large, the inner and outer pericarps are not the same size; the fruit on the infructescence is densely clustered; the tender branches have a large, nearly spongy pith; the leaflets of the leaflets are brownish-red[2][3].

It grows in Damiaoshan, Guangxi and is found under dense forests in valleys about 1000 meters above sea level [2].[6]
The leaflets are oblong, 6-10 cm long and 2-3 cm wide. The edge of the leaf has separated serrated lobes, and the tooth tips are pointed. Flowering period from April to May, fruit period from August to September. Grows in Ganluo, Sichuan. Seen in the sparse forest in the mountains at an altitude of 2400 meters[2].[7]
