Robinson (1980a: 91) . Type:— BRAZIL. Minas Gerais: in glaerosis Serra da Lapa, November 1824, L. Riedel 1127 (lectotype: LE [not seen], designated by MacLeish (1987: 287); isolectotypes: F e! [F0051076F (fragment)], P [P00683136, P00683137]) ( Fig. 37 A–C ).

Distribution and habitat: — Brazil (Minas Gerais, endemic of the Serra do Cipó and the Diamantina Plateau). Campo rupestre; 1000–1300 m.

Taxonomic notes: —Distinctive features of this species are the linear to narrowly lanceolate leaves with glabrous adaxial surface. Similar to Prestelia purpurascens , but the latter species differs from P. eriopus in its lanceolate to oblong-spathulate leaves with densely lanate adaxial surface (becoming glabrescent with age), and higher number of florets per capitulum (8–10 vs. 5–7).
