Figs 9D, S 2

Type: BRAZIL. Minas Gerais: Lagoa Santa, s.d., Palácios et al. 3262 (holotype LIL) .

Shrub to ca. 60 cm tall. Stems erect, branched, tomentose. Leaves with 2 leaflets, petiolate. Leaflets 9–25 × 5–8 mm, ovate to elliptic, strigose. Stipules elliptic, 4–6 veined. Inflorescences spiciform, axillary, 20 cm long. Bracteoles 9–11 × 4–5 mm, elliptic, 5–7 veined, punctate, sericeous, green. Loment with 3–5 articles; articles 1.5–2 × 1–2 mm, not reticulate-veined, bristle-like trichomes absent.

Distribution and habitat: Brazil, endemic. It occurs at high elevations (approx. 1400 m) in the Campo rupestre vegetation of the Savanna biome.

Conservation Status: Near Threatened (NT). The fact that Zornia hebecarpa is restricted to Campo rupestre areas, indicates that the species is confined to a relatively small area within its larger distribution range (EOO= 477,731.185 km ²; AOO= 156.000 km ²).

Notes: Zornia hebecarpa morphologically resembles Z. ramboana , as both share sericeous bracteoles and loment articles without trichomes. However, Z.hebecarpa has leaflets measuring 9–25 × 5–8 mm, and a strigose indumentum (vs. leaflets measuring 5–35 mm × 2–11 mm, and a tomentose indumentum in Z. ramboana ).

Representative specimen examined: BRAZIL. Minas Gerais: Lagoa Santa, s.d. Simart 17181 (P).
