Abstract: Zornia melanocarpa Fort.-Perez, Syst. Bot. 41(2): 299. 2016. Fig. S2 Type: BRAZIL. Minas Gerais: Parque Estadual do Rio Preto, São Gonçalo do Rio Preto, 24 February 2015, Fortuna-Perez, Vatanparast, Cândido, Soldevila & Zeferino 2100 (holotype BOTU–39518!; isotypes BOTU–39519!, OUPR, US). Shrub to ca. 15 cm tall. Stems erect, not branched, villous. Leaves with 2 leaflets, petiolate. Leaflets 7–20 × 1.5–10 mm, elliptic to ovate, villous. Stipules lanceolate, 5–7 veined. Inflorescences spiciform, axillary, 5 cm long. Bracteoles 5–7 × 2–4 mm, lanceolate, 5–6 veined, punctate, villous, green. Loment with 2 articles; articles 1.6–2 × 1–1.2 mm, reticulate-veined, bristle-like trichomes absent. Distribution and habitat: Brazil, endemic. This species occurs in the Espinhaço range, growing in the Campo rupestre vegetation of the Savanna biome. Conservation Status: Data Deficient (DD). Zornia melanocarpa is currently known from only a single collection from the Espinhaço mountain range, an important biodiversity hotspot in Brazil. It is currently classified as DD due to a lack of information about its threats (EOO=0.000 km²; AOO= 4.000 km ²). Notes: Zornia melanocarpa is distinguished by its shrubby growth habit, with erect, unbranched, villous stems, and by its loments, characterized by two articles and the absence of trichomes. Representative specimen examined: BRAZIL. Minas Gerais: Parque Estadual do Rio Preto, São Gonçalo do Rio Preto, 18°07′45.1′′ S; 43°21′58.7′′ W, 993 m alt., 24 February 2015, Fortuna-Perez, Vatanparast, Cândido, Soldevila & Zeferino 2100 (BOTU).
