Distribution : "A native tropical American species, growing from Mexico and the Caribbean to Paraguay and Argentina. Introduced and widely distributed in tropical and subtropical regions of the Old World" (Morrone et al. 2014). Voir aussi GBIF (sub Setaria sulcata Raddi 1823 & Setaria poiretiana (Schult.) Kunth 1829).

Statut biogéographique : En Guyane paraît tout à fait indigène, dans l'intérieur connu par exemple des bords de la Comté et de l'Approuague, de la montagne Cacao de la haute Camopi ou de l'inselberg de la borne frontière n°4.

Type : "In marginibus fossarum udarum prope Catumby, non procul ad urbe Rio de Janeiro." [protologue].
Brésil, Rio de Janeiro, "Invenitur in marginibus fossarum udarum prope Catumby, non procul ab urbe Rio de janeiro" [Raddi, 1823], "Panicum sulcatum Bert. Excerpt. de re herb. p.14 n.14 // Attulit ex Brasilia et benevole communicavit D. Raddi sub nominee Panici plicati. 1820." [scripsit: A. Bertoloni on BOLO] (LT: BOLO [photo: fig. 7 in Baldini, Taxon, 55(2): 479-480. 05/2006; désigné par O. Morrone et al., Syst. Bot. Monogr., 96: 121. 2014]; ILT: PI [2 planches], FI [3 planches]).
D'après Baldini (Taxon, 55(2): 479-480, fig. 7. 05/2006): "Raddi (1823: 50) based his Setaria sulcata on Panicum sulcatum Bertol., nom. ill. hom., published by Bertoloni (1820), on the basis of the Raddi collection detailed above. It follows that the name Setaria sulcata Raddi, although intended as a new combination, may be treated as a nomen novum for Panicum sulcatum Bertol., under Art. 58.1 of the ICBN (Greuter & al., 2000). Under Art. 7.3, the specimen, used by Bertoloni and housed in the Herbarium Bertolonii (BOLO!) is considered to be the holotype of Setaria sulcata Raddi.
There are also isotypes of Setaria sulcata Raddi (≡ Panicum sulcatum Bertol.) at FI, consisting of three sheets. All of these specimens have spikelets similar to the holotype. Two of them also have narrow-lanceolate leaf-blades, as does the holotype. The other specimen has leaf-blades 42–43 × 3.7–4.3 cm, much bigger than those in the other specimens of Setaria sulcata Raddi from FI and PI. The leaves of this latter specimen resemble those of the isotype of Panicum elongatum Poir. [= Setaria poiretiana (Schult.) Kunth] seen by the present authors at FI-Webb!, which consists of only one leaf-blade, 43 × 4 cm, an inflorescence 29 × 2.5 cm, and lanceolate spikelets, 4–4.2 × 1–1.1 mm, with glumes more acute than Setaria sulcata Raddi."
