Lychnophora brunioides var. alpicola Mart. ex Candolle (1836: 80) . Type:— BRAZIL. Minas Gerais: in Serro Frio ad Tejuco , alt. 5000 ped., C.F.P. von Martius 1476 (495) (holotype: M e! [ M0029467 ]; isotype: G-DC e! [ G00464280 (fragment)]).

Distribution and habitat: — Brazil (Minas Gerais, known only from the Pico de Itambé). Campo rupestre; 1880–2052 m.

Taxonomic notes: —The presence of an inconspicuous obtriangulate leaf sheath helps distinguish this species from Lychnophora pinaster (which has similar leaves but without leaf sheath). Coile & Jones (1981) excluded L. brunioides from Lychnophora and considered it a member of Piptolepis . However, the latter genus is defined by its pad-like leaf sheath and caducous phyllaries, characters absent from L. brunioides . Also similar to Lychnophorella , but these species also have a pad-like leaf sheath base (vs. obtriangulate).
