Notes. The holotype was deposited in B but was destroyed in 1943. We are designating the specimen at New York ( NY) as lectotype. This is in good condition and is the only duplicate that has the annotation “Ex. Mus. Bot. Berol”.

Martinez et al. (2002) and Jorgensen et al. (2014) consider Lycianthes amatilanensis to be a synonym of Lycianthes inaequilatera (Rusby) Bitter (1919: 439) . However, examination of the types of these taxa clearly indicates them to be different species. Lycianthes amatitlanensis can be recognized for having erect branches, shiny leaves, and conspicuous calyx appendages (2.0-3.0 mm long), which are linear and pilose at anthesis. On the other hand, Lycianthes inaequilatera has zig zag branches, dull leaves, inconspicuous calyx appendages, less than 1 mm long, which are glabrescent at anthesis. We consider Lycianthes amatilanensis is a distinct taxon and not synonymous with L. inaequilatera , thus corroborating the previous observations of Rojas and Darcy (1997) and Bohs (2015).
