Taxonomic notes: — Sida ulei View in CoL belongs to Sida sect. Muticae ( Krapovickas 2003b) by the following morphological traits: leaf blades narrow to broadly ovate or weakly 3-lobate, subcordate to cordate at base, upper surface with stellate trichomes, sometimes mixed with simple trichomes, lower surface with stellate trichomes, usually mixed with simple and bifurcate trichomes; flowers and fruits crowded in axillary and terminal glomerules or, sometimes, solitary, subsessile to shortly pedicellate; calyx 6–10 × 5–7 mm, prominently 10-angled, stellate-puberulent; corolla pale rose or salmon, with a magenta center; mericarps (8)–9–(10), submuticous, the spines up to 0.8 mm long with minute and retrorse stellate trichomes; and seeds dark brown or vinaceous.

Distribution and habitat: — Sida ulei is placed to Sida sect. Cordifoliae and is endemic to the Caatinga of northeastern Brazil, from Ceará to north Minas Gerais ( Krapovickas 2003b). In Pernambuco, it is found in several localities from Mata to Caatinga, along the humid forest fragments ( brejos de altitude) and extended further south or the forested areas located in the caatinga domains of the extreme western end of the state (Chapadões Cretáceos e Araripe). This species grows on sandy, humid soils and rocky outcrops, on the inselbergs along the forest areas or along roadsides, restricted to few and widely spaced individuals.
