Botanical history
The species was first described in 1900 by Merritt Lyndon Fernald as Athenaea nelsonii , but moved to a new section Brachistus of the genus Witheringia in 1969 by Armando Hunziker , so the species was named Witheringia nelsonii . However, the three species in this section were given genus status again in 1981, so that the species was assigned the name combination Brachistus nelsonii , which is valid today, for the first time .
