Abstract: Zornia microphylla Desv., Mem. Soc. Linn. Par. 4: 325. 1826. Fig. S1 Type: SAINT LUCIA. January 1821, Plee s.n. [neotype P–02142437! designated by R.H. Mohlenbrock (1961)]. Shrub to ca. 40 cm tall. Stems prostrate, branched, glabrous. Leaves with 2 leaflets, petiolate. Leaflets 2.2–15 × 2.6–8 mm, ovate to obovate, glabrous. Stipules lanceolate, 1–3 veined. Inflorescences spiciform, axillary, 15 cm long. Bracteoles 5–6.3 × 1.7–2.5 mm, elliptic to lanceolate, 1–3 veined, punctate, glabrous, green. Loment with 3–7 articles; articles 1.5–2.1 × 1.7–2.4 mm, reticulate-veined, bristle-like trichomes 0.5 mm long. Distribution and habitat: Antigua, Barbados, Cuba, Dominica, Dominican Republic, Grenada, Guadaloupe, Guyana, Saint Lucia, Trinidad and Tobago, Venezuela. It occurs in Tropical Dry Forest. Conservation Status: Vulnerable (VU). The fact that the species occurs mostly on islands adds to its vulnerability, due to a limited AOO (EOO= 1,561,277.527 km ²; AOO= 236.000 km ²). Notes: Zornia microphylla is distinct from the other species by its prostrate stems and small (2.2–15 × 2.6–8 mm) ovate to obovate leaflets. Representative specimen examined: ANTIGUA.
