Type: BRAZIL. Goiás: entre le Rio Bananal et le Rio Torto , 13 May 1895, Glaziou 20917 (holotype F–0BN002251 !; isotypes F–0059984F !, G–00370098 !, K–000328079 !, NY–01477289 !, P–02142434 !, S–9533 !) .

Zornia villosa Glaz., Mém. Bull. Soc. Bot. France 53: 133. 1906; nom. nud.

Shrub to ca. 70 cm tall. Stems prostrate, branched, hirsute. Leaves with 4 leaflets, petiolate. Leaflets 10–25 × 5–15 mm, ovate to obovate, pubescent to glabrous. Stipules lanceolate, 5–7 veined. Inflorescences spiciform, axillary, 20 cm long. Bracteoles 10–12 × 5–7 mm, oblong, 6–8 veined, punctate, pilose, green. Loment with 3–4 articles; articles 1.5–2 × 1.5–2, not reticulate-veined, bristle-like trichomes absent.

Distribution and habitat: Brazil, endemic. This species occurs at high elevations (approx. 1200 m) in Cerrado vegetation of the Savanna biome.

Conservation Status: Endangered (EN). Zornia glaziovii has a limited distribution. It has relatively small EOO of 99,095.246 km ² and an even smaller AOO of 28,000 km ².

Notes: Zornia glaziovii morphologically resembles Zornia ulei , but it differs by its stems with a hirsute indumentum (vs. villous in Z. ulei ). Furthermore, the spiciform inflorescences of Z.glaziovii are 20 cm long and the bracteoles have a pilose indumentum (vs. inflorescences 7 cm long and bracteoles with a villous indumentum in Z. ulei ).

Representative specimens examined: BRAZIL. Goiás: Cristalina , 4 April 1973, W.R. Anderson 8160 (K).
