Taxonomic notes: —The species belongs to section Sidae ( Table 1 View TABLE 1 ) Series Viarumae. This Series is characterized by the presence of 5 mericarps ( Krapovickas 2014). The species is also characterized by the persistent stipules after leaf fall, by calyx 5 mm long ( Monteiro-Filho 1949) and corolla white with adaxial red basal spot ( Figures 12F–J View FIGURE 12 , 14V View FIGURE 14 ).
Distribution, habitat and conservation status: — Sida viarum is a South American species ( Argentina, Brazil, Bolivia and Paraguay) that reaches as far north, southern Mexico ( Fryxell 1988, Zuloaga et al. 2008, Alverson et al. 2014). In Brazil the species occurs in north, northeast, midwest, southeast and south region, but not in all states ( Zuloaga et al. 2008, Bovini 2020). In Rio Grande Sul, the species is distributed in Bush grassland, Inland sub-montane grassland, Sandy grassland, Coastal grassland, and occasionally in Aristida grassland ( Figure 13 View FIGURE 13 ). The species is here considered Least Concern (LC) because it has a large EOO (greater than 3,000,000 km ²) and an AOO around 2,000 with the available records.
