Treelet 0.3 – 2 m tall; stem erect, unbranched, apical bud aborting after flowering, lateral bud developing afterwards (Chamberlain’s Model), glabrous, dark brown, bark fistulose, when young smooth, when mature striate. Stipules 12 – 15 × 6.5 – 8 mm, caducous, triangular, margins revolute. Leaves spirally arranged to subverticillate, clustered in groups of 6 – 22 at the apex of the stem; petiole 5 – 12 mm long, canaliculate; blade oblanceolate, 23 – 45 × 5.7 – 11.7 cm, chartaceous, base rounded, margins entire at the base and serrate towards the apex, slightly revolute and undulate, apex acute to attenuate, adaxial and abaxial surfaces dark green, glabrous; venation eucamptodromous, midvein sulcate on adaxial surface, prominent on abaxial surface, green, secondary veins 5 – 12, impressed on adaxial surface, prominent on abaxial surface, green, tertiary veins inconspicuous, glabrous, light-green. Inflorescence terminal, 19 – 29 cm long, thyrsoid, erect, congested, the axis rugose with punctate white dots, glabrous, set with groups of 2 – 9 flowers in depauperate uniparous cymes of the bostryx type; basal bracts imbricate, sterile, unequal, triangular, 6.4 – 8.6 mm long, similar to the stipules, persistent, dark brown; peduncle bracts 3 per node, alternate, sterile, unequal, narrowly triangular, 7.8 – 10.4 mm long, persistent, brown; rachis bracts solitary, alternate, inserted at the base of the bostryx, falcate, 8.8 – 11.5 mm long, persistent, brown; bostryx congested, rachis inconspicuous, pedicel articulation 2.4 – 5.2 mm long, cylindrical, bostryx bract 1 per branch, narrowly triangular to linear, 2.2 – 2.9 mm long, persistent, reddish-brown. Flowers with 1 – 2 bracteole per flower, narrowly triangular to linear, 1.7 – 2.4 mm long, early caducous, reddish-brown; pedicels 7.6 – 11 mm long above the bostryx, straight to curved, papillate; sepals 5, imbricate, elliptic to obovate, 7.1 – 9.2 × 1.6 – 2.2 mm, concave, base rounded, margin hyaline, apex acute, adaxial surface papillate, reddish, abaxial surface glabrous, thicker in the middle, orange-yellowish; petals 5, obovate, 10 – 12 × 5 – 6 mm, occasionally thicker at the base and along the central vein, base attenuate to unguiculate, margin entire, apex reflexed and rounded, glabrous, yellow; stamens 10, arranged in a circle around the ovary, anthers erect, sessile, sigmoid, 5.5 – 6.4 mm long, transversely rugulose, poricidal, yellow; gynophore columnar, 0.8 – 1 × 0.8 – 1.1 mm, thickening near the apex, salmon pink; gynoecium superior, 5 - carpellate, fertile units 5, 0.9 – 1.2 × 1.2 – 2 mm, oblate, salmon pink; style 1, erect, filiform, gynobasic, 0.7 – 0.9 mm long, stigma punctiform, salmon pink. Fruit with carpophore 5.6 – 11.5 × 3.9 – 10.6 mm, oblate, rugose, when immature greenish, salmon pink at the base, when mature red; mericarp 1, rarely 5, ellipsoid or obpyriform, erect or obliquely disposed on the carpophore, 10.4 – 12.3 × 5.2 – 6.4 mm, pericarp thin, rugose, when immature greenish, when mature brownish; seed 1, 8.8 – 10.5 × 5.0 – 5.6 mm, testa membranous, slightly rugose.	en	John Teixeira, Luíza, Araújo, Michelly de Deus Felipe, Deccache, Lara Serpa Jaegge, Fraga, Claudio Nicoletti de (2025): When nomenclature and morphology unravel an enigma: the true identity of Ouratea crassinervia (Ochnaceae).
