Abstract:
Morphological variations among all the ten species of Ipomoea were observed both qualitative and quantitatively. Thirteen quantitative characters were taken into consideration and their mean values were compared statistically. Comparative analysis revealed variations from species to species. Qualitative characters concerned with root/tuber, stem/leaf, flower and capsule/seed were examined. Almost all the species of Ipomoea are of herbaceous and climbing habit except I. aquatica, it is amphibious in nature. Most of the species showed leaves to be lobed with various shape such as ovate-oblong, cordate, broadly ovate, ovate-cordate etc. except I. quamoclit where the leaves were found to be pinnately paired and cut up to the midrib. Flowers were observed to be few in axillary cymes in most of the species and in few species flowers were many in terminal cymes, except I. pes-tigridis where the flowers were head like involucrate in auxillary cymes. On the other hand, seed colours were also found to vary but slightly in the species of Ipomoea examined in the present investigation.
