Zornia diphylla var. gracilis f. microphylla Chodat & Hassl., Bull. Herb. Boiss. Ser. View in CoL 2 (4): 888. 1904. Type : PARAGUAY. s.loc., 1897, Hassler 2981 (holotype G–00400364!; isotypes BM–000081072!, P–00631812!).

Shrub to ca. 80 cm tall. Stems erect, branched, glabrous. Leaves with 2 leaflets, petiolate. Leaflets 13–35 × 3–15 mm, ovate to elliptic, pubescent to glabrous. Stipules elliptic to lanceolate, 6–11 veined. Inflorescences spiciform, terminal, 30 cm long. Bracteoles 8–14 × 4–6 mm, elliptic, 4–6 veined, punctate, glabrous, green. Loment with 4–7 articles; articles 1.5–3 × 1.5–2.5 mm, not reticulate-veined, bristle-like trichomes absent.

Distribution and habitat: Argentina, Brazil, Guyana, Paraguay, Venezuela. It occurs in Savanna.

Conservation Status: Near Threatened (NT). The disjunct distribution adds complexity to conservation planning, requiring a comprehensive and coordinated approach across the countries where Zornia pardina is found (EOO= 7,003,218.759 km ²; AOO= 320.000 km ²).

Notes: Zornia pardina morphologically resembles Z.crinita , but it differs by its glabrous indumentum (vs. villous to sericeous in Z. crinita ). Also, the loment has no bristle-like trichomes in Z. pardina (vs. bristle-like trichomes 1 mm long in Z. crinita ).
