Abstract: Zornia herbacea Pittier, Bol. Soc. Venez. Cienc. Nat. 6: 192. 1940. Fig. S5 Type: VENEZUELA. Anzoátegui: Sabanas de Guaraguara, cerca de Santomé, 25 March 1940, Pittier 14337 (holotype US; isotype VEN–5282!). Shrub to ca. 20 cm tall. Stems prostrate, branched, puberulent. Leaves with 2 leaflets, petiolate. Leaflets 15–20 × 3–5 mm, ovate to lanceolate, strigose. Stipules elliptic, 3–5 veined. Inflorescences spiciform, axillary, 10 cm long. Bracteoles 6–8 × 3–4 mm, lanceolate, 5 veined, punctate, strigose, green. Loment with 4–6 articles; articles 2–2.5 × 1.5–2 mm, not reticulate-veined, bristle-like trichomes 0.5 mm long. Distribution and habitat: Venezuela, endemic. It occurs in Savanna. Conservation Status: Data Deficient (DD). Zornia herbacea is known only from a few collections. Information about its distribution is insufficient to make an accurate conservation assessment (EOO=0 km²; AOO= 8.000 km ²). Notes: Zornia herbacea morphologically resembles Zornia ramboana, but it differs by its prostrate stems (vs. erect in Z. ramboana) and its 10 cm long inflorescences (vs. 20 cm in Z. ramboana). Representative specimen examined: VENEZUELA. Zulia: near Santa Rosa de Tierra, Maracaibo, s.d., Pittier 10701 (NY, US).
