. in Proc. Biol. Soc. Wash. 28: 172. 1915 – Holotype: U.S.A. Maryland: Montgomery County, Plummers Island in the Potomac River, 4 Oct 1915, P.C. Standley 12500 (US barcode 00102846!; isotype: US barcode 00067672!).

= Celosia paniculata L., 

Sp. Pl.: 206. 1753 ≡ Iresine celosia L  ., Syst. Nat., ed. 10: 1291. 1759, nom. illeg. ≡ Iresine celosioides  L., Sp. Pl., ed. 2: 1456. 1763, nom. illeg. ≡ Iresine paniculata (L.) Kuntze  , Revis. Gen. Pl. 2: 542. 1891, nom. illeg., non I. paniculata (Mart.) Spreng., Syst. Veg. 4(2): 103 1827 – Lectotype (designated by Reveal & Nicholson in Taxon 38: 504. 1989): Clayton 576 (BM barcode BM000051634 [image!]).

Note. – Since the Clayton specimen comes from Virgina (U.S.A.), the currently accepted name for this entity is Iresine  rhizomatosa as the only taxon of Iresine  growing in this area, even if the species limits in relation to I. diffusa  have not yet been clarified.

Taxonomic status: Species limits not yet studied in detail (B).
