Zornia laevis Schltdl. & Cham. Linnaea

Zornia laevis Schltdl. & Cham. Linnaea 5: 582. 1830. Fig. S3 Type: MEXICO. Collibus apricis prope Jalapam, August 1828, Deppe & Schiede s.n. (holotype HAL–0098427!). Shrub to ca. 60 cm tall. Stems prostrate, branched, glabrous. Leaves with 2 leaflets, petiolate. Leaflets 12–36.3 × 1.3– 12.2 mm, elliptic to lanceolate, glabrous. Stipules elliptic, 3–5 veined. Inflorescences spiciform, axillary, 18 cm long. Bracteoles 13.5–14 × 4.8–7 mm, ovate, 5–7 veined, punctate, glabrous, green. Loment with 3–5 articles; articles 1.6–2.4 × 1.3–1.6 mm, reticulate-veined, bristle-like trichomes absent. Distribution and habitat: Mexico, endemic. It occurs in Tropical Dry Forest. Conservation Status: Data Deficient (DD). With only three points of occurrence, there is insufficient information available to assess the conservation status of the species (EOO= 249,828.333 km ²; AOO= 12.000 km ²). Notes: Zornia laevis differs from other species by its prostrate and glabrous stems. The loments have a reticulate-veined pattern on their articles and no trichomes. Mohlenbrock (1961) proposed a neotype of Zornia laevis based on Muller 1625 (NY) from Vera Cruz, Mexico. However, here we disregard this neotype as the species was originally described from material collected by Deppe & Schiede s.n. and deposited in the Martin-Luther-Universität herbarium (holotype HAL–0098427!). Representative specimen examined: MEXICO. Jalisco: Guadalajara, s.d., Palmer 495 (US); Vera Cruz: Orizaba, s.d., Muller 1625 (NY).
