Stems erect, branched, glabrous. Leaves with 2 leaflets, petiolate. Leaflets 12–46 × 5–10 mm, ovate to lanceolate, glabrous. Stipules lanceolate, 5–6 veined. Inflorescences spiciform, axillary, 30 cm long. Bracteoles 11–14 × 5–6 mm, ovate–lanceolate, 5–7 veined, punctate, glabrous, green. Loment with 4–9 articles; articles 1.5–2 × 1.5–2 mm, reticulate-veined, bristle-like trichomes 2 mm long. Distribution and habitat: Brazil, Guyana, French Guiana, Martinique, Suriname. It occurs preferentially in coastal regions of Tropical Moist Forest. Conservation Status: Vulnerable (VU). Zornia glabra has a disjunct distribution, with a preference for coastal regions. In Brazil, where the species mostly occurs, Z.glabra is found in Atlantic Forest vegetation (EOO= 6,300,226.298 km ²; AOO= 508.000 km ²). Notes: Zornia glabra morphologically resembles Zornia reticulata. However, the bracteoles of Z. glabra are ovate (vs. lanceolate in Z. reticulata).
