Taxonomic notes: — Sida galheirensis is placed in Sida sect. Cordifoliae differing from all other species by having ovate to oval-lanceolate or elliptic leaves, lower surface densely covered by hyaline to flavous stellate trichomes; terminal flowers aggregated in panicles or racemes formed by corymbs; calyx 10-ribbed, stellate-tomentose; corolla showy, up to 35 mm in diameter, the petals yellow-gold with a dark-red center, 45–55 stamens, the filaments organized in 3–5 phalanges; and 7–12 biaristate mericarps with spines retrorsely barbed. Monteiro (1936) described and illustrated two varieties, genuina and subgracilis, adding to the variety genuina two forms, subtrilobate and angustodontia. These taxa were distinguished based on leaf morphology, inflorescence type and indumentum color. However, S. galheirensis is a polymorphic species, and these features are within the range of the variation of this species, and the geographic distribution of the varieties and forms is the same. Therefore, these taxa are here proposed as synonyms. On other hand, as the author hasn’t mentioned any holotype in the protologue for each of these taxa, the names were here lectotypified in accordance with Article 9.2 of the Melbourne Code ( McNeill et al. 2012).

Distribution and habitat: —It is endemic to the Caatinga biome of the Brazilian semiarid region, and occurs in all of the northeastern states, from Maranhão to Bahia, and at the north of Minas Gerais. S. galheirensis occurs widely in Pernambuco along the Caatinga zone, in different habitats, including a mix of the dry caatinga vegetation, dry forest and enclaves of brejos de altitude. Many populations occur densely on dry, rocky and arid soils, along roadsides or similarly open or disturbed habitats, also in inselbergs and rocky outcrops.
