Abstract: Zornia megistocarpa Mohlenbr., Webbia 16 (1): 102. 1961. Fig. S4 Type: MEXICO. Oaxaca: Cerros de Salina Cruz, 18 October 1919, C.Conzatti 3677 (holotype: US–00001993!; isotypes: GH–00241646!, MEXU–01169252!, NY–00842229!). Shrub to ca. 25 cm tall. Stems prostrate, branched, sericeous. Leaves with 2 leaflets, petiolate. Leaflets 10–27 × 5–10 mm, ovate, sericeous. Stipules lanceolate, 5–7 veined. Inflorescences spiciform, axillary, 10 cm long. Bracteoles 12–15 × 7–9 mm, ovate, 7–9 veined, punctate, sericeous, green. Loment with 3–4 articles; articles 3–3.2 × 3–3.4 mm, reticulate-veined, bristle-like trichomes 0.8 mm long. Distribution and habitat: Mexico, endemic. It occurs in Tropical Dry Forest. Conservation Status: Data Deficient (DD). Zornia megistocarpa is known only by a few collections from the state of Oaxaca, Mexico. Therefore, due to the limited information available about its distribution, it is not possible to assess the level of threat facing this species (EOO= 584.141 km ²; AOO= 16.000 km ²). Notes: Zornia megistocarpa is distinguished by its prostrate, sericeous stems combined with ovate, also sericeous, leaflets and bracteoles. Representative specimen examined: MEXICO. Oaxaca: Cerro de Picacho, s.d., Purpus 7202 (NY).
