Pastore 427</i> (CTBS 4683!, Fig.5). <b>Comments:</b> — <i>Eriosema simplicifolium</i> can be recognized by its prostrate habit, usually procumbent to decumbent, by having unifoliate leaves, with lanceolate lanceolate and racemes generally do not extend beyond the leaves (Cândido <i>et al.</i> 2019). The articles that refer to the species <i>E. simplicifolium</i> do not mention its distribution to the state of Bahia, however, there is a collection for the municipality of Formosa do Rio Preto, identified by a specialist. <b>Subshrub</b> prostrate, 0.4–1 m tall, decumbent or procumbent stems, cylindrical, yellowish pilose to tomentose. <b>Stipules</b> 4.5–5.5 mm long, connate, lanceolate, persistent. <b>Leaves</b> unifoliolate, persistent when the plant is fertile, leaflets uniform in size and shape on the same plant, 3.5 × 1.2 cm, lanceolate to ovate, apex acuminate to acute, chartaceous, base with three veins not evident, entire margin slightly serrate, venation camptodromous, petiole 2–3.5 mm long. <b>Inflorescences</b> terminal or axillary racemes, 2–5 cm long, usually shorter than mature leaves, glabrescent, pauciflorous (2–10-flowered), flowers laxly arranged, 7–13.5 mm long. <b>Fruit</b> 2.5–6 mm (Fig.4.A). <b>Habitat, distribution, and phenology:</b> —This species is widely distributed in Brazil (Fig.6) and can be found in Cerrado and Amazon environments (BFG 2021). In the municipality of Cunha, it was found in grassy and humid terrains (Menezes 2021) and collected with flowers in February, March, and July and fruits in February and November (Cândido <i>et al.</i> 2014). <b>Material examined</b>:— BRAZIL: Amapá: Macapá, Campo Experimental do Cerrado, km 45 da rodovia BR 156, trecho Macapá-Ferreira Gomes, 05 May 1988, <i>J.
