AB - For the last 175 years the name Ipomoea staphylina has been applied throughout much of tropical Asia to one of the few lianoid species of Ipomoea found there. Study of herbarium specimens and living plants revealed that three distinct taxa are passing under the name I. staphylina. Two problems emerged: a pernicious confusion dating back to the 1930s, in which collections of Merremia boisiana (Gagnepain) Ooststroom were misidentified as I. staphylina, and, a taxonomic problem that requires delimitation of two similar species of Ipomoea, both heretofore called I. staphylina. The nomenclature is discussed for names pertinent to this taxonomic problem and all names are typified. A key to the three similar taxa and an illustration of their diagnostic characters are provided to aid in recognizing them. The synonymy and geographic distribution are summarized for the two species of Ipomoea and an index of numbered collections examined is provided.
