Polygonum plebeium R.Br., Prodr. Fl. View in CoL Nov. Holland. 420 (1810). – Type: Australia, Broad

Sound, 19 ix 1802, R. Brown s.n. [Iter Austral. 2994] (lectotype BM [ BM001015740 ], designated by Graham in Turrill & Milne-Redhead, Fl. Trop. E. Africa, Polygon. 13 [1958]) .

Polygonum indicum Roth , Nov. Pl. Sp. 208 (1821). – Avicularia indica (Roth) Didrichs., Bot. Not. 1850: 187 View in CoL (1850). – Polygonum roxburghii Meisn., Prodr. 14(1): 93 (1856), nom. illegit., superfl. – Polygonum herniarioides Del. var. roxburghii Boiss., Fl. Orient. View in CoL 4: 1038 (1879). – Type: India orientalis, B. Heyne s.n. (lectotype B [B 10 0279363], designated by Turner, Taxon 70: 410 [2021]).

Meisner cited numerous synonyms under Polygonum roxburghii and the four varieties of it that he recognised. Many were cited with question marks, so nomenclaturally they can be put aside. Of those cited without an expression of doubt, Avicularia indica Didrichs. , is the key one. Didrichsen published this name, stating that his species was identical with Polygonum indicum Roth. I therefore take Avicularia indica to be a new combination based on Polygonum indicum Roth. Polygonum roxburghii Meisn. therefore represents a superfluous renaming of P. indicum Roth , which should probably be considered a synonym of P. plebeium R.Br.
