Zornia harmsii Herter, Rev. Sudamer. Bot. View in CoL 6: 154.1940, nom. nud.

Shrub to ca. 30 cm tall. Stems prostrate, branched, pubescent. Leaves with 4 leaflets, petiolate. Leaflets 5–40 × 1–3 mm, linear, pubescent. Stipules ovate, 4–5 veined. Inflorescences spiciform, axillary, 20 cm long. Bracteoles 5–9 × 2.5–4 mm, oblong, 8–10 veined, punctate, glabrous, green. Loment with 3–4 articles; articles 1.5–2 × 1–1.5, not reticulate-veined, bristle-like trichomes absent.

Distribution and habitat: Brazil, endemic. It occurs in sandy soils of the Caatinga vegetation in Tropical Dry Forest.

Conservation Status: Endangered (EN). Zornia harmsiana is considered endangered due to its limited distribution range within the Caatinga in Brazil (EOO= 300,080.950 km ²; AOO= 120.000 km ²).

Notes: This species is easily recognizable by its typically prostrate branches, linear leaflets and oblong bracteoles.
