Caragana sibirica as a pre-Linnaean name was used by Royen (Fl. Leyd. Prodr. 537. 1740) and considered by Linnaeus (loc. cit.) to be a synonym of Robinia caragana. Although Fabricius used the name C. sibirica (Enum., ed. 2, 421. 1763), which would appear to have priority over C. arborescens, only generic names are validly published there, and so the first valid publication of C. sibirica as a binomial was in the later publication by Medikus (Vorles. Churpfälz. Phys.-Öcon. Ges. 2: 365. 1787).
