22. Sida ulei Ulbr. in Ule (1909: 225) ( Figs. 6D , 7B ). Type:— BRAZIL. Bahia, am See bei Maracas, Oktober 1906,

blühend, Ule 6966 (holotype, B, destroyed, F 9399, photo!).

= Sida salzmannii Monteiro (1969: 33) . Type:— Sida purpurascens Salzm. ex K.Schum. (see Monteiro 1969: 33, Krapovickas 2003b: 129).

Taxonomic notes: — Sida ulei belongs to Sida sect. Muticae ( Krapovickas 2003b) by the following morphological traits: leaf blades narrow to broadly ovate or weakly 3-lobate, subcordate to cordate at base, upper surface with stellate trichomes, sometimes mixed with simple trichomes, lower surface with stellate trichomes, usually mixed with simple and bifurcate trichomes; flowers and fruits crowded in axillary and terminal glomerules or, sometimes, solitary, subsessile to shortly pedicellate; calyx 6–10 × 5–7 mm, prominently 10-angled, stellate-puberulent; corolla pale rose or salmon, with a magenta center; mericarps (8)–9–(10), submuticous, the spines up to 0.8 mm long with minute and retrorse stellate trichomes; and seeds dark brown or vinaceous.

Distribution and habitat: — Sida ulei is placed to Sida sect. Cordifoliae and is endemic to the Caatinga of northeastern Brazil, from Ceará to north Minas Gerais ( Krapovickas 2003b). In Pernambuco, it is found in several localities from Mata to Caatinga, along the humid forest fragments (brejos de altitude) and extended further south or the forested areas located in the caatinga domains of the extreme western end of the state (Chapadões Cretáceos e Araripe). This species grows on sandy, humid soils and rocky outcrops, on the inselbergs along the forest areas or along roadsides, restricted to few and widely spaced individuals.

Representative specimen: — BRAZIL. Pernambuco. Bonito, 26 July 1996, fr., J.A. Siqueira-Filho & G.S. Baracho 446 (UFP).
