21. Sida tuberculata R.E. Fries (1908: 33) View in CoL var. pseudo-rhombifolia Monteiro (1949: 522) ( Figures 8 View FIGURE 8 , 11L–Q View FIGURE 11 , 14T View FIGURE 14 )

Lectotype (designated by Krapovickas 2014: 111):— BRAZIL. Minas Gerais: Belo Horizonte, 29-I-1934. H. Monteiro 711 (RBR!, isotype US!).

Taxonomic notes: — S. tuberculata var. pseudo-rhombifolia belongs to section Sidae ( Table 1 View TABLE 1 ) and is a species morphologically related to Sida viarum and Sida rhombifolia ( Krapovickas 2014, Monteiro-Filho 1949). It differs from these species by the presence of 6–8 mericarps (rarely nine), vs. 5 mericarps in S. viarum and 9–14 mericarps in S. rhombifolia ; presence of simple trichomes on the margins of the calyx lobes; flowers solitary or crowded in subsessile axillary glomerules, the pedicels up to 15 mm long on solitary flowers ( Figures 11L–Q View FIGURE 11 , 14T View FIGURE 14 ) ( Krapovickas 2005, Brandão et al. 2017).

Distribution, habitat and conservation status: —The species occurs in Venezuela, Bolivia, Paraguay, Argentina, Uruguay and Brazil (northeast, midwest, southeast and south) ( Krapovickas 2014, Bovini 2020). In Rio Grande do Sul the species occurs in Park grassland, Sandy grassland, Shallow soil grassland, Inland sub-montane grassland, Bush grassland, Highland grassland, Aristida grassland, Coastal grassland and Inland subtropical Forest ( Figure 8 View FIGURE 8 ). The species is here considered Least Concern (LC) because it has large EOO and AOO, since it is a frequent and ruderal species, and widely distributed.
