Taxonomic notes: — Sida linifolia is in the section Stenindae ( Fryxell 1985) . This section includes only two species known (the other, S. hassleri Hochr. , occurs in Brazil and Paraguay). Sida linifolia differs from this and all other species of Sida by having its leaves narrowly linear or linear-lanceolate, 1.4–15.5 × 0.2–1.1 cm; umbelliform inflorescence; calyx partially covering the fruit; corolla minute and white with dark vinaceous center, and mericarps 7–9, vinaceous and blackish, muticous.

Distribution and habitat: —This species is commonly distributed throughout Mexico, the Caribbean and Panamá; and occurs widely in much of South America south to Paraguay and Brazil ( Fryxell 1985, Fuertes 1995) where it is found in all Brazilian regions, from Amazonas to Rio Grande do Sul. In State of Pernambuco, S. linifolia grows in small populations in dried river beds, plantations, and in ruderal places or wastelands. It occurs throughout the state, from Littoral to Caatinga, in disturbed secondary forests, grassland, dry caatinga vegetation and brejos de altitude.
