Distribution and habitat: — Brazil (Goiás, Minas Gerais). Campo rupestre; 600–1560 m.
Taxonomic Notes: —A species distinct by its densely lanate stems, large leaves and capitula with ca. 75 florets. Heterocoma robinsoniana is related, but differs from it in its villous to lanulose slender stems and smaller leaves (4.5–13.5 × 1.4–5.9 cm vs. 11.5–26.5 × 5–10 cm). Also H. lanuginosa resembles H. ekmaniana , but is distinct from the latter by possessing capitula in clusters (vs. usually solitary) and 25–50 florets per capitulum (vs. ca.75). The allopatric distribution also helps to set apart the three species: H. lanuginosa is restricted to the mountains of the Espinhaço Range (Minas Gerais), H. ekmaniana occurs in Goiás State mountain areas (rarely in southwestern Minas Gerais) and H. robinsoniana is found in the Serra da Canastra (southwestern Minas Gerais).
