Zornia pardina Mohlenbr., Webbia

Zornia pardina Mohlenbr., Webbia 16 (1): 84. 1961. Fig. S5 Type: BRAZIL. Rio Grande do Sul: Torres, 19 January 1955, Rambo 56482 (holotype MO–714955!; isotype PACA–28235!). Zornia diphylla var. gracilis f. microphylla Chodat & Hassl., Bull. Herb. Boiss. Ser. 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). Representative specimen examined: ARGENTINA.
