    Inflorescences
    Racemes homomorphic, short, axillary, condensed; the rachis cylindrical, 0.5 – 1 cm, villous; peduncle 3 – 7 cm
    Bracts
    Floral bract 1 – 2 mm, linear, deciduous
    Flowers
    Flowers 5-merous, basal ones pedicellate 1 – 1.5 mm, apical ones subsessile; calyx 2 – 3 × 2 – 3 mm, campanulate, pubescent; corolla 6 × 3 mm, campanulate, sericeous

    Distribution
    Brazil: Espírito Santo, Minas Gerais and Rio de Janeiro.
    Ecology
    Semi-deciduous forest and ombrophilous dense forest.
    Conservation
    Vulnerable (VU). After exhaustive work on herbarium collections and field expeditions, we discovered that Abarema villosa occurs in places of potential ore exploration in Minas Gerais state and is subject to the effects of these human activities. This species also occurs in small populations from Rio de Janeiro and Espírito Santo states. Only a few mature individuals are known and the species is therefore considered to be facing a high risk of extinction in the wild.
    Note
    The species epithet refers to the conspicuous villous indumentum of the leaflets and branches. This new species is similar to Abarema brachystachya, but differs in the villous abaxial leaflet surface, pilose and truncate ovary. Abarema villosa occurs in southeast Brazil, in Minas Gerais, Espírito Santo and Rio de Janeiro. A. brachystachya is more widely distributed than A. villosa, extending from the coastal Atlantic Forest of Bahia, Espírito Santo, Minas Gerais, Rio de Janeiro, São Paulo, Paraná and Santa Catarina.
