The specimen Hassler 6441 [G 00085101 (two sheet)!] is designated as a lectotype for B. balansae , because this collection presents a higher number of duplicates in different herbaria, it is a complete specimen, and bear the original label with the name of the species with De Candolle’s handwriting in 1903. The specimen designated as a lectotype (G 00085101) was mounted on two sheets and represents a unique specimen of this collection ( Gautier et al. 2016) .
