13. Sida potentilloides A. Saint-Hilaire (1825: 178) View in CoL ( Figures 5 View FIGURE 5 , 7A–E View FIGURE 7 , 14M View FIGURE 14 ).
Lectotype (designated by Rodrigo 1944: t. 22):— BRAZIL. Rio Grande do Sul. “Secus silvam prope São Nicolao, in provincia Missionum”, s.d., A. St.-Hilaire C2/2708 bis (P barcode 02285462! [digital image]; isolectotypes P barcode 02285461! [digital image], P barcode 02285460! [digital image], MPU barcode 016972! [digital image], US barcode 00097962! [digital image]).
= Sida anarthra Ekman (1910: 15) View in CoL Lectotype (designated here):— ARGENTINA. Misiones. Posadas, Bonpland , in campo humido in marginibus silvulae, etc, 15 January 1908, E.L. Ekman 145 ( S 14-46283 ! [digital image]; isolectotype S 14-46282 ! [digital image], LD barcode 1691486! [digital image], LP barcode 004304! [digital image], NY barcode 00222011! [digital image]).
Nomenclatural notes: — Ekman (1910) designated the collection Ekman 145 as type from Sida anarthra . However, there are five specimens of this collection, all syntypes, deposited in herbaria S, LD, LP and NY. The specimen S 14-46283 was designated as a lectotype, because it is representative of the species .
Taxonomic notes: —According to the description of sections of Sida from Fryxell (1985) we included the species in section Sidae by the leaves basally entire and distally dentate (dentate almost to the base in this species), base cuneate, sometimes more or less rhomboid, and number of mericarps 7–11 ( Table 1 View TABLE 1 ). Striking features of this species are leaves dentate almost to the base, blades generally narrowly elliptic, narrowly oblong or oblong, abaxial surface tomentose, with margins coarsely serrate; corolla dark yellow, and mericarps with long aristae, greater than 1 mm long ( Figures 7A–E View FIGURE 7 , 14M View FIGURE 14 ). In the present work, photos of the species in its habitat are presented for the first time.
Distribution, habitat and conservation status: — Sida potentilloides occurs in Paraguay, Argentina, Uruguay, and in southeast, and south of Brazil ( Zuloaga et al. 2008, Bovini 2020). In state of Rio Grande do Sul the species grows generally in Araucaria Forest, sometimes associated with Highland grassland, but also in Inland subtropical Forest and Bush grassland ( Figure 5 View FIGURE 5 ), in edges of Forests, in ruderal environments and shrubland. The species is Least Concern (LC) because it has large EOO and AOO, since it is a frequent and often ruderal species.
