Taxonomic note:— Based on morphology of the leaves, the infra-especific classification used Bennett (1874) is not relevant. Bredemeyera divaricata is recognized by the leaves with glabrous blades on the adaxial surface and puberulent on the abaxial surface mainly on the mid vein; panicles 15–40 cm; flowers with pedicel between 1–2 mm, lateral petals slightly widening to the apex, internally pubescent, style bended, and ovary glabrous. Bredemeyera lucida ( Bentham 1842: 101) Klotzsch ex Hasskarl (1864: 189) cannot be easily separated from B. divaricata and might be synonymous. There are two specimens of Badiera divaricata in P that constitute the type collection. Although they were marked as “ Polygala divaricata ” in De Candolle’s handwriting, instead “ Badiera divaricata ”, the specimens without a doubt represent the type collection of Badiera divaricata , also supported by the original De Candolle´s note “v.s. in h. Mus. Par.”. De Candolle´s mistake is easily understood since the genus Bredemeyera , although described by Willdenow in 1801, was delimited much later by Bentham (1842, as Catocoma ) and then by Hasskarl (1864) who applied the correct name, Bredemeyera , for that genus ( Marques 1980). In fact, the name Badiera divaricata was used by De Candolle with an explicitly stated doubt about its correctness as applied to that species and expressed in his note (“an hujus generis?”). Not surprisingly, the original material was annotated by De Candole, in his own handwriting, as “ Polygala divaricata ”. Therefore, it must be considered the second known Bredemeyera described by De Candolle under a different genus, another one was Securidaca hebeclada De Candolle moved to Bredemeyera hebeclada (De Candolle) J.F.B.Pastore ( Pastore 2010) .
