Zanthoxylum multijugum (Chinese: 多叶花椒) is a woody climber from the family Rutaceae.¹²³⁴

As a species of woody climbers, Zanthoxylum multijugum has been found in "open forests" and "hillside thickets".¹ It has a native range that includes North and Central Yunnan as well as Guizhou within China.¹ It has been found from 1,500 metres (4,921 feet) to 2,200 metres (7,218 feet) meters above sea level.¹

Its leaves have been observed with 19-51 leaflets and minimal or no stalks.¹ The leaves vary in shape (lanceolate, elliptic, or ovate), tend to be asymmetrical, have spots, and have been seen with blunt, rounded, or mucronate apexes.¹ Its young branchlets have been found to be pale reddish brown in color.¹ Prickles have been found on stems, branches, and leaf rachises.¹ Flower petals have been found to be a pale yellowish green color, are oblong in shape and are about 2 millimetres (0.079 inches) in size.¹ Their flowering period is from May to June, while their fruiting period lasts from October to November.¹ Male flowers have four stamens and broadly ovate anthers while female flowers have pedicels that are two to five millimeters in size with fruits about one centimeter in size.¹ Fruit follicles have been observed as brownish red in color, about five millimeters in diameter, and with their apex beaked.¹ Their seeds have been found to be from 4 to 4.5 millimeters in diameter.¹

In 1889, it was published as a species in Plantae Delavayanae as part of a specimen collection by Père Jean Marie Delavay and taxonomy work of Adrien René Franchet.⁵² It was accepted as a plant species in 2008's Flora of China where it was identified to appear in Yunnan and Guizhou.⁴ There have been three identified synonyms of the species, including Fagara mengtzeana, Fagara multijuga, and Zanthoxylum multifoliolatum.
