8. Sida glomerata Cavanilles (1785: 18) ( Figs. 2D – E , 4B ). Type:— Jussieu s.n. (holotype, P-JU 12249, as IDC microfiche, photo!).

Taxonomic notes: — Sida glomerata belongs to Sida sect. Distichifolia ( Krapovickas 2003a) because of the following morphological traits: herbs or subshrubs variously pubescent, indumentum with stellate trichomes, more or less abundant and dense, mixed with simple hairs, variable in length up to 2 mm long, and bifurcate, more or less appressed and less frequent hairs; dimorphic stipules 2–15 mm long, lanceolate to oval-lanceolate, falcate, 3–5-nerved, ciliate; leaves elliptic-lanceolate and distichous with upper surface flattened in lateral branches; shorter flowers mostly arranged in glomerular 3–5-flowered cymes in the leaf axils; calyx blackish; and mericarps 5, brownish or blackish, usually short-spinescent.

Distribution and habitat: — Sida glomerata occurs widely throughout the Caribbean and tropical America ( Fryxell 1985), from Costa Rica to Argentina and all Brazilian regions, from Amazonas to Santa Catarina. It also occurs widely in Pernambuco, from Littoral to Caatinga, and in different habitats (mixed secondary forests and associated types, restinga and coastal terraces, dry caatinga vegetation and brejos de altitude), and in ruderal places or wastelands. Grows in small populations.

Representative specimen: — BRAZIL. Pernambuco. Igarassu, Usina São José, 24 September 2012, fr., J.L. Brandão & L. Lima 283 (PEUFR).
