10. Sida nemorensis Martius ex Colla (1833: 416) (Figures 5, 6A–D, 14J). Lectotype (designated by Fryxell 1976: 591, as “ holotype ”): Brazil. Bahia: “Rio Belmonte [Rio Jequitinhonha]”, 1816, Anonymous [Wied] s.n. (TO! [digital image]). Taxonomic notes: — Colla (1833) and Fryxell (1976) attributed the type collection to Martius, who never collected at Rio Jequitinhonha. Wied collected over 100 species at “Rio Belmonte” (Moraes et al. 2013). Sida nemorensis can be distinguished from other species of section Nelavagae by the aristate mericarps, by the presence of glandular trichomes in the stems, and by the erect habit (Figures 6A–D, 14J; Table 1) (Krapovickas 2006). In the present work, photos of the species in its habitat are presented for the first time. Distribution, habitat and conservation status: — Sida nemorensis occurs in Bolivia, Paraguay, Argentina and southeast, midwest and south of Brazil (Krapovickas 2006, Bovini 2020). In state of Rio Grande do Sul, the species was found so far only in two places, in Coastal grassland associated with Butia catarinensis Noblick & Lorenzi (2010: 164) and in Inland subtropical Forest (Figure 5), in edges. With the available records, the species presents an EOO of 2,734,283.060 Km² and an AOO of 170 Km². Although it can be considered EN by the AOO, conditions B(a), B(b) and B(c) were not met. Therefore, the species is here considered Least Concern (LC). Representative specimens: — BRAZIL. Rio Grande do Sul. Derrubadas, Parque Estadual do Turvo, s.d., P. Brack et al. 1721 (ICN); Torres, Campo Bonito, BR 101 Km 06, 10 February 1983, A. Krapovickas & C. L. Cristóbal 38480 (CTES, HAS).
