21. Sida uchoae Monteiro (1969: 29) ( Fig. 7B ). Type:— BRAZIL. Pernambuco: Recife, à margem da estrada, Estação Experimental do Curado, 20 January 1953, fr., H. Monteiro & R. Uchoa 3932 (holotype, RBR!).

= Sida recifensis Monteiro , nom.nud. in herb. (RBR!, as “ holotype ”).

Taxonomic notes: — Sida uchoae is placed in the section Sidae by the following morphological traits: stems with stellate trichomes; stipules 5–8 × 0.5–1 mm, linear-lanceolate to subfalcate, 2–4-nerved; leaf blades ovate to oval-oblong or oblong-lanceolate, truncate at base, with stellate trichomes on both surfaces, short-petiolate, the petioles 2–5 mm long; flowers commonly solitary or weakly paired or aggregated, short-pedunculate, the pedicels not articulate; calyx stellate-pubescent, sepals ciliate; and mericarps 8, biaristate, the spines 1 mm long. This species was first reported by Monteiro-Filho (1969) as morphologically similar to S. acuta (sect. Distichifolia ), but differing by the leaves spirally disposed, pedicels not articulate and small mericarps. S. uchoae belongs to the series Sida and is similar to S. poeppigiana ( Schumann 1891: 339) Fryxell (1992: 106) .

Distribution and habitat: —Previously known only from the type locality [two collections in F (1802838, 1802839, photos!), from Minas Gerais and Goiás, were identified by P.A. Fryxell, in 1974, as S. uchoae , but has not been confirmed], the species grows in sandy soils of small patches of remaining wet forest on the west side of municipality of Recife, in the Littoral zone.

Representative specimens: — BRAZIL. Pernambuco. Known only from the type.
