Distribution and habitat: — Pleopeltis minarum is restricted to the states of Minas Gerais and Bahia ( Fig. 10C View FIGURE 10 ), and occurs mainly in the outcrops along the quartzite and ferruginous fields along the Espinhaço Mountains between 600–1800 m.

Notes: —This species is easily recognized by the presence of dense, lanceolate, generally whitish scales on all parts of the lamina. It is usually confused with P. hirsutissima , but this species can be easily differentiated by its brownish scales with base rounded and long-acuminate to the filiform apex. In addition, P. hirsutissima occurs as an epiphyte and P. minarum is always epipetric.
