20. Sida spinosa Linnaeus (1753: 683–684) View in CoL ( Figures 10 View FIGURE 10 , 11E–K View FIGURE 11 , 14S View FIGURE 14 )

Holotype:—“ Habitat in India ” ( LINN 866.1 View Materials ! [digital image]).

Taxonomic notes: — Sida spinosa belongs to section Spinosae ( Fryxell 1985) ( Table 1 View TABLE 1 ). One of its striking features is the presence of a small projection, tubercle, such as a spine, but not sharp, in the base of petioles. This feature can also be found in Sida riedelii , a very similar species, that is distinguished by the hyaline and crumbly dorsal face of its mericarps ( Schumann 1891, Krapovickas 2005), vs. mericarps with complete and reticulated dorsal face, which does not easily break ( Figures 11E–K View FIGURE 11 , 14S View FIGURE 14 ). The species Sida tuberculata can also present a tubercle at the base of the petioles, which are generally smaller. However, Sida tuberculata , has more than five mericarps.

Distribution, habitat and conservation status: —This species is pantropical, and also occurs in adjacent temperate zones ( Fryxell 1985, Fuertes Aguilar 1995, Brandão et al. 2017). In Brazil S. spinosa occurs in northeast, southeast, midwest and south ( Bovini 2020) and in all regions of Rio Grande do Sul state ( Figure 10 View FIGURE 10 ), in ruderal environments and anthropized grasslands, except in Coastal grassland. The species is here considered Least Concern (LC) because it has large EOO and AOO, since it is a frequent and ruderal species, widely distributed.
