Racemes heteromorphic, short, axillary; cylindrical rachis, 0.5 – 1 cm, pubescent; peduncle 3 cm
    Bracts

    Flowers
    Flowers 5-merous; basal ones pedicellate 0.2 mm, apical ones, subsessile; calyx 2 × 2 mm, campanulate, pubescent mainly on the teeth; corolla 6 × 3 mm, campanulate, sericeous mainly on the lobes; stamens 3.5 cm, staminal tube enclosed in the corolla, the free parts of the filaments exserted more than 2.5 cm beyond the corolla Central flower subsessile, calyx 3 × 3 mm, campanulate, pubescent mainly on the teeth; corolla 9 × 3 mm, sericeous mainly on the lobes

    Distribution
    Brazil: Espírito Santo.
    Ecology
    Semi-deciduous forest and restinga.
    Conservation
    Critically Endangered (CR). After exhaustive work in herbaria collections and field expeditions, we conclude that Abarema barnebyana has a population of only a few mature individuals, known from a small area of the coastal region in Espírito Santo state. This species is endemic to the Atlantic Domain, an endangered tropical hot spot in Brazil. This species is threatened by real estate offices near the coastline and faces a high risk of extinction in the wild.
    Note
    The name honours Leguminosae taxonomist, Rupert C. Barneby. Abarema barnebyana resembles A. jupunba but differs from it in its obtuse apices, absence of indumentum on the abaxial surface of the leaflets, the leaflet size which is smaller in A. barnebyana (1.1 – 1.4 × 0.6 – 0.8 cm) than in A. jupunba (1.5 – 2.5 × 0.8 – 1 cm), and the ovary indumentum which is glabrous in A. barnebyana and pilose in A. jupunba. A. jupunba occurs in northeastern Brazil and in the Amazonian forest. A. barnebyana is also similar to A. limae, but differs in its leaflet size: smaller and with an obtuse apex in A. barnebyana (versus acute apex, 1.8 – 2.5 × 0.7 – 1 cm, in A. limae).
