Fig. S1

Type: HONDURAS. Quebrada Dantas: 20 km noroeste de Yuscarán, drainage of the Río Yeguare , 23 November 1948, Molina 1660 (Lectotype here designated: US–00001995!; isolectotypes: F–0059982F !, GH–00241663 !, MO–126299 !, US–01107554 !) .

Shrub to ca. 30 cm tall. Stems erect, branched, glabrous. Leaves with 2 leaflets, petiolate. Leaflets 15–30.6 × 1–1.7 mm, linear to filiform, glabrous. Stipules elliptic, 3–5 veined. Inflorescences spiciform, axillary, 11 cm long. Bracteoles 5–6 × 1.2–1.5 mm, linear, 3 veined, punctate, glabrous, green. Loment with 2–3 articles; articles 2.5–3.2 × 2–2.5 mm, reticulate-veined, bristle-like trichomes 1.5 mm long.

Distribution and habitat: Honduras, Mexico, Nicaragua, Venezuela. It occurs in sandy soils of Savanna.

Conservation Status: Data Deficient (DD). Zornia lasiocarpa has a lack of adequate collection data, with only four known occurrences (EOO= 558,050.277 km ²; AOO= 24.000 km ²).

Notes: The linear to filiform leaflets are particularly noteworthy in Z. lasiocarpa ; and also its loments with 2–3 articles, bearing bristle-like trichomes up to 1.5 mm long. Mohlenbrock (1961) cited the type materials based on the collection Molina 1660, but did not designate a holotype from amongst the available duplicates. Therefore, we here make a second step lectotypification.

Representative specimen examined: HONDURAS. Moran: beyond Las Mesas, s.d., Standley 29254 (US). MEXICO. Sinaloa: Mazatlan, n.d, Rose et al. 13828 (US). VENEZUELA. Distrito Federal: Augustura to Ciudad Bolivar, s.d., Grosourdy 13 (P).
