Mesua assamica (King & Prain) Kosterm. (Calophyllaceae) was described in 1901 as Kayea assamica by King and Prain on the basis of specimens collected from the erstwhile Dibrugarh district of Assam, India. Later in 1969, the taxon was transferred from the genus Kayea to Mesua by Kostermans. As no holotype was designated by the authors either while describing the taxa or even while merging it with Mesua, a lectotype is designated here.
