Abstract
Mangoes are the fruits of Mangifera species, most of which are distributed in Southeast Asia. M. caloneura Kurz is a common wild mango in mainland Southeast Asia where it is utilized locally for its edible fruit. This species has been a subject of recent attention in explorations of mango folk taxonomy. However, species assignment to M. caloneura is difficult because there are two different descriptions: one indicates the presence of only 1 fertile stamen per flower and the second indicates 5 fertile stamens. The type diagnosis by Kurz describes 1 fertile stamen per flower; nevertheless, Kurz has been retained as the binomial authority in all subsequent literature, even in works describing the presence of 5 fertile stamens. Here, we track taxonomic developments over 138 years to demonstrate how inconsistencies have arisen.
