Kuntze (1891b: 970), nom. illeg., non Linnaeus (1763: 1169). Type:— BRAZIL. F. Sello(w) s.n. (800) (lectotype: B

e! [ B100094257 ] designated by MacLeish (1987: 277); isolectotypes: BR e! [ BR0000005267996 ], F e! [ F0049525 F

(fragment)], P [P02511277]) ( Fig. 16 A ).

Albertinia bicolor Gardner in Baker (1873: 161), nom. nud., non A. bicolor Candolle (1836: 81) [= Paralychnophora bicolor (DC.) MacLeish (1984c: 106) ].

Distribution and habitat: — Brazil ( Bahia and Minas Gerais). Campo rupestre, cerrado and margins of secondary forests; rare in caatinga and only one record in restinga; 600–1810 m.

Taxonomic Notes: —Best recognized by the following combination of characters: grey lepidote stems, capitula fused nearly their entire length, cypsela cylindrical and pappus subpaleaceous. Some populations in the state of Bahia have capitula fused for 1/2 of length and have been misidentified as Eremanthus glomerulatus , but in the other characters they clearly differ from the latter species. The name “ Albertinia bicolor Gardner , non DC.” is cited by Baker (1873: 161) in the synonymy of E. incanus ; however Gardner (1846: 236) wrote at the end of the description of Albertinia candolleana : “Near A. bicolor, DC. , but abundantly distinct”. We understand that Gardner did not intend to publish a new name.
