Our lack of understanding of L. mutabilis is compounded by taxonomic problems caused by poor species delimitation and a surfeit of names. To address this I am undertaking specimen-based work to delimit L. mutabilis and its putative close relatives, in order to assemble a new taxonomic account of this group. Morphological studies based on herbarium specimens and field observations have led me to the hypothesis that L. semperflorens and L. eanophyllus are putative progenitors of L. mutabilis. These two species have similar distributions in the Province of Loja in Southern Ecuador and North-Central Peru. This suggests a possible origin of domestication for L. mutabilis in this part of the Andes where there is a rich history of sophisticated early civilizations.
