10. Monteiroa smithii Krapovickas (1962: 61-63) View in CoL . Holotype: BRAZIL. Santa Catarina: Campo Alegre, Pinheiral, lower slopes of Morro Iquererim , 1000-1300 m, 8 November 1956, L. B. Smith & R. M. Klein 7386 (US barcode 00098195! #; Isotypes: R barcode 000200398! #, HBR!). Figures 20 View FIGURE 20 and 22 View FIGURE 22 .

Taxonomic notes: —The species is characterized by: erect shrubs up to 2.7 m high; leaves (1.4-) 3–9 (-14) × (1-) 3–7 (-12) cm, discolorous, pentalobed, dentate-crenate, basally cordate, adaxial surface with sparse stellate trichomes and abaxial surface densely stellate-pubescent; calyx 0.6–1 × 0.2–0.5 cm, epicalyx bracts 0.9–1.2 × 0.4–0.9, lanceolate-ovate; corolla pink; mericarps 0.4–0.5 × 0.4–0.5 cm.

Distribution, habitat and conservation status: —This species occurs in Brazil ( Paraná and Santa Catarina States) ( Figure 21 View FIGURE 21 ), and grows in wetlands and margins (or neighborhoods) of rivers of Provincia Paranense ( Cabrera & Willink 1973), in the highland grasslands in ecotone with the Araucaria forest, at elevations of 800 to 1600 m. The species presents an extent of occurrence of 5,305.687 km 2 and an area of occupancy (AOO) of 60 km ², and is here considered Endangered (EN) by the AOO, by the habitat severely fragmented and by the continuing decline estimated and projected in its AOO and extent and quality of habitat, criteria B2ab (ii, iii). This is due to the fact that a large part of their populations are threatened by the increase in urbanization in the metropolitan region of Curitiba-PR and in the region of São Bento do Sul-SC.
