Zornia myriadena Benth., Fl. Bras. (Martius
Zornia myriadena Benth., Fl. Bras. (Martius) 15(1): 85. 1859. Figs 4C, 11, S 2 Type: BRAZIL. Bahia: s.loc., s.d., Martius s.n. [lectotype M–0233826! designated by Fortuna-Perez and De Azevedo (2011)]. Shrub to ca. 80 cm tall. Stems decumbent, branched, glabrous to villous. Leaves with 4 leaflets, petiolate. Leaflets 5–17 × 3–6 mm, obovate, villous to glabrous. Stipules obovate, 4–6 veined. Solitary flower. Bracteoles 5–5.5 × 2–2.5 mm, elliptic, 6–7 veined, punctate, villous, green. Loment with up to 15 articles; articles 2–3 × 2–2.3 mm, not reticulate-veined, bristle-like trichomes absent. Distribution and habitat: Cuba, Brazil, Jamaica. It occurs mainly in Tropical Dry Forests. Conservation Status: Near Threatened (NT). The disjunct distribution adds complexity to the assessment, emphasizing the need for targeted conservation measures in both regions of occurrence (EOO= 4,946,100.470 km ²; AOO= 364.000 km ²). Notes: Due to the presence of solitary flowers, Z.myriadena resembles Z. echinocarpa, but it differs by an absence of trichomes on the loment (vs. bristle-like trichomes 1 mm long in Z. echinocarpa).
