2. Sida cerradoensis Krapovickas (1969: 11) View in CoL ( Figures 1G–L View FIGURE 1 , 2 View FIGURE 2 , 14E View FIGURE 14 ).
Type:— Sida potentilloides A. Saint-Hilaire (1825: 178) subsp. elata Hassler (1910a: 38) . Lectotype (designated here):— PARAGUAY. Sierra do Amambay, “ in campis ‘Serrados”, Jul., Hassler 10552 (P barcode 02285398! [digital image]; isolectotypes LIL 393646! [digital image], NY barcode 00222039! [digital image], UC barcode 941206! [digital image], MPU barcode 016973! [digital image]).
Nomenclatural notes: — Brandão et al. (2017) presented the type of the species as a holotype, deposited in herbarium P. However, there are several specimens from the collection Hassler 10552 in other herbaria, and so all specimens are syntypes. According to the International Code of Nomenclature of algae, fungi and plants, 2018, from January 1, 2001, a lectotypification will only be effective when accompanied by the term “ lectotypus ” or by its abbreviation or its equivalent in a modern language (Art. 9.23, Turland et al. 2018), and when including the phrase “designated here” (Art. 7.11). Therefore, a lectotypification was necessary.
Taxonomic notes: —The species belongs to Sect. Cordifoliae ( Monteiro-Filho 1936, Brandão et. al. 2017) ( Table 1 View TABLE 1 ), and is easily distinguished from related species by the presence of two long aristae in the mericarps, undulate (wavy) leaf margin, apex of the calyx and leaf margins dark-red or violaceous-purplish, calyx with trichomes 1–2 mm, and sulcate petioles ( Krapovickas 1969, Brandão et al. 2017). Another diagnostic feature of this species are its relatively large, 16 × 10 mm, yellow-orange (sometimes salmon) petals, often with a red adaxial basal spot ( Figures 1G–L View FIGURE 1 , 14E View FIGURE 14 ).
Distribution, habitat and conservation status: —This species is known from Bolivia, Paraguay and Brazil ( Hassler 1910 a, Krapovickas 1969, Zuloaga et al. 2008, Alverson et al. 2014, Bovini 2020). In Brazil, the species occurs in North, Northeast, Central-West, Southeast and South regions, but not in all states ( Bovini 2020). In Southern Brazil occurs in Paraná, Santa Catarina (first record) and Rio Grande do Sul (first record) states, found only in two localities in the latter, in Coastal grassland ( Figure 2 View FIGURE 2 ), in ruderal environments and anthropized grasslands. According to IUCN (2017) criteria, the species is here considered Least Concern (LC) with an EOO of 4,253,166.732 Km² and an AOO about 1,200 Km² and because it is a species that also occupies ruderal environments. Furthermore, it does not meet the criterion B(b) and B(c).
