Ipomoea is the largest genus of the family Convolvulaceae which consist of nearly 1650 species among which 150 species are from India. They are herbs, shrubs or usually twinning. The present study intended to analyse qualitative and quantitative morphological features of five selected species of genus Ipomoea species shows ecological variations. For the morphological analysis plant accessions are collected from different regions of Kerala. The collected plant accessions are conserved in the green house of the college garden. Plant specimens were identified by using the flora, morphological analysis was carried out by using observation and measuring techniques. The observation of the study revealed that certain qualitative characters have similarity among five selected species of Ipomoea and some other character shows variation from species to species and accessions especially the colour of corolla and quantitative characters.
