Recent field work in Lao PDR and the Malaysian state of Sabah produced multiple collections of a large-flowered Ipomoea that appeared to be the same species. The disjunct distribution, however, seemed anomalous. Checking type images and other specimens led to the name I. cambodiensis Gagnep. & Courchet, described from Cambodia. A full description, distribution map, discussion of the taxonomy, ecology, and perceived relationships, plus a compilation of all specimens seen to date are provided for this enigmatic and heretofore little known species.Mahidol UniversityAgricultural and Biological SciencesArticleSCOPUS10.5252/a2014n2a14
