16. Sida salviifolia Presl (1835: 110) ( Figs. 5E – F , 7A ). Type:— MEXICO. prope Acapulco, Haenke s.n. (holotype, PR,

as “ Sida salviaefolia ”, photo!; isotype, BM, n.v., PR, n.v .).

= Sida allemanii Monteiro (1936: 41) . Type:— BRAZIL. Pernambuco, Alagôa de Baixo, 31 March 1933, H. Monteiro 349 (holotype, RBR!).

Taxonomic notes: — Sida salviifolia is placed in Sida sect. Cordifoliae ( Fryxell 1985) due to the distinctive characters which include: leaf blades linear, linear-elliptic or linear-lanceolate, upper surface with stellate trichomes mixed with bifurcate and simple trichomes, lower surface densely covered with stellate trichomes; flowers solitary or paired in the axils and crowded in racemes at the apices; pedicels articulated 2–3 mm below the calyx; calyx 4.5–6 × 3.5–5 mm; sepals rhombic, the lobes 2–3 mm long, acute, internally glabrous; corolla yellowish or white with a reddish center; stamens 10–12; and mericarps 6–7, biaristate, the spines 2–3 mm long, and retrorsely barbed.

Distribution and habitat: —Occurs in Mexico, the Caribbean and South America, from Venezuela to Bolivia and Brazil ( Fryxell 1985, Fuertes 1995), where it is found at the present in the northeastern region ( Monteiro-Filho 1936, 1969). New records of this species for Pernambuco are presented here and bridge a gap of more than 80 years, since its first and only record from 1933. It grows on sandy or stony soils in the Caatinga zone, and along roadsides, restricted to few and widely spaced individuals.
