5. Sida cerradoensis Krapovickas (1969b: 19) ( Figs. 1G – H , 4A ). Type:— Sida potentilloides Saint-Hilaire (1827: 178) subsp. elata Hassler (1910: 38) . PARAGUAY. Sierra do Amambay, in campis ‘Serrados’, Jul., fl., fr., Hassler 10552 (holotype, P, photo!; isotype, LIL, n.v.).

Taxonomic notes: — Sida cerradoensis belongs to the Sida sect. Cordifoliae , due to distinctive characters, including: leaf blades 2–4 × 0.8–1.7 cm, slightly elliptic to ovate-lanceolate, margin irregularly dentate and continuously dark-red or violaceous-purplish; flowers clustered in axillary or terminal racemes, calyx 0.8–1 × 0.7–0.8 cm, not accrescent; corolla yellow-orange or salmon, stamens 45–55 in number; and mericarps (8–)9–12 prominently biaristate, the spines 0.4–0.6 cm long and retrorsely barbed. In addition, this species differs from all known Cordifoliae by verrucose stems, stipules, leaf margins and apex of the calyx dark-red or violaceous-purplish, and by its larger aristae.

Distribution and habitat: — Sida cerradoensis is widespread, known from Bolivia to Uruguay and Brazil, where it is found at the North and Central-West to South regions ( Krapovickas 1969b). In northeast Brazil, it occurs from Rio Grande do Norte to Bahia. A new record of this species from State of Pernambuco is presented here, with small and medium populations growing in pioneer formations along Littoral, in sandy soils of restinga, coastal terraces and cerrado.

Representative specimen: — BRAZIL. Pernambuco. Igarassu, Refúgio Ecológico Charles Darwin, 19 Fev. 1996, fl., fr., M. Oliveira et al. 207 (UFP).
