03C887CE3E4DFFEFFF130411CCA9F8AF.taxon	distribution	Distribution and habitat: — The circumscription of S. glutinosa with respect to its closest relative, S. glabra Miller (1768: Sida no. 14), has recently been clarified by Baracho & Agra (2016). This species occurs in tropical America, from northwest Mexico and the Caribbean to Argentina and Brazil (Krapovickas 2006) where it is found from the Northeast to Central-West and Southeast Regions. It is considered quite rare in the State of Pernambuco. Only a single record was previously reported by Monteiro-Filho (1949) and re-collected in 1996, after a gap of 50 years, in an area of Brejo de Altitude, Mata zone of state. On the other hand, some collections of Sida from herbarium IPA (see Albuquerque 35 AJ, Andrade-Lima 8989, Andrade-Lima et al. 9303, Lima et al. 734, and Pereira et al. 874) have been incorrectly assigned to S. glutinosa and this error has been propagated, but there is no doubt that all collections refers to S. ulei Ulbr.

Distichifolia (Krapovickas 2014) by the following morphological features: Stem and branches covered with minute stellate trichomes; leaves with appressed and antrorse simple trichomes on the adaxial surface, and minute stellate trichomes on the abaxial surface; depauperate axillary inflorescences with 1 – 2 flowers; staminal tube with simple trichomes, and mericarps 8 – 10, blackish and short-aristate. It’s also closely related to S. glomerata, but can be distinguished by the trichome morphology of its leaves, calyx and pedicel, inflorescence type in the axils, and number and morphology of the mericarps. It is often reported in the literature as Sida acuta or Sida carpinifolia.	en	Brandão, José Lourenço, Baracho, George Sidney, Sales, Margareth Ferreira De, Filho, Marcelo Paulino Viegas (2017): Synopsis of Sida (Malvaceae, Malvoideae, Malveae) in the state of Pernambuco, Brazil.

03C887CE3E55FFF7FF130275CB10FB1B.taxon	distribution	Distribution and habitat: — This species is Indo-Pacific and American in distribution (Krapovickas 2014). In the Americas, S. ulmifolia is known from southern United States and Mexico to the Caribbean and northern South America, from Colombia to north and northeast Brazil. In Pernambuco, the species has been recorded growing in small populations and on sandy soils from Littoral to Mata, in disturbed areas of forests and plantations, and at the Archipelago of Fernando de Noronha.

03C887CE3E55FFF7FF1304EDC888F8CB.taxon	description	Taxonomic notes: — Sida urens is placed in Sida subsect. Conglomerata (Fryxell 2009) due to the distinctive characters which include: stems and leaves hirsute covered with long simple trichomes, 5 – 7 mm long, mixed with bifurcate and scattered short stellate trichomes; leaf blades narrow to broadly oval-cordate, with simple, bifurcate, and stellate trichomes on both surfaces, the lower surface with more dense stellate trichomes; flowers and fruits crowded in subsessile axillary and terminal glomerules or, sometimes, solitary, subsessile to shortly pedicellate, the pedicels up to 5 mm long, not articulate; calyx obtrullate to rhombic, hirsute, ciliate sepals; corolla yellowish, orange or salmon, with or without purplish center; and mericarps 5, 2 – 2.5 mm long, muticous, dorsal surface externally covered with punctiform glandular trichomes.	en	Brandão, José Lourenço, Baracho, George Sidney, Sales, Margareth Ferreira De, Filho, Marcelo Paulino Viegas (2017): Synopsis of Sida (Malvaceae, Malvoideae, Malveae) in the state of Pernambuco, Brazil.

03C887CE3E55FFF7FF1304EDC888F8CB.taxon	distribution	Distribution and habitat: — Sida urens is another species of the genus that has a wide distribution, and occurs in tropical Africa, the Caribbean, and tropical America, from southern Florida and Mexico to northern Argentina and Brazil, where it is sparsely found in all regions (Krapovickas 2006). The species is also found in Hawaii (Starr et al. 2002, Wagner et al. 2012). It is found throughout the State of Pernambuco from Littoral to the brejos de altitude of the agreste portion of the Caatinga zone. This species is restricted to few and widely spaced individuals and grows in disturbed and urbanized areas such as dried river beds, plantations, roadsides and in ruderal places or wastelands.

03C887CE3E54FFF6FF1300AFCA00FDE9.taxon	description	Taxonomic notes: — Sida castanocarpa is placed into Sida sect. Malacroideae (Krapovickas 2007) as a member of the Sida ciliaris complex, and occurs in Northeastern Brazil and Goiás. The type material of this cryptic species was not available for examination, excepting online images. On the other hand, one of the paratypes of S. castanocarpa, from IPA (Krapovickas et al., 38749!), is ambiguous and similar to S. brittonii León (1919: 172). The original description of this species is conflicting with the morphological variation presented in this study of S. brittonii and S. harleyi Krapovickas (2007: 239), and has led to mis-identifications. Given the considerable taxonomic confusion and the need to verify which morphological characters are taxonomically significant by observing the type specimens of S. castanocarpa, this species is excluded from the present study.	en	Brandão, José Lourenço, Baracho, George Sidney, Sales, Margareth Ferreira De, Filho, Marcelo Paulino Viegas (2017): Synopsis of Sida (Malvaceae, Malvoideae, Malveae) in the state of Pernambuco, Brazil.
