Micromorphological Studies of the Genus Ipomoea L. (Convolvulaceae) in Nepal
Himalayan Biodiversity, 2017
Ipomoea is a large and complex genus, which comprises the largest number of species within the family Convolvulaceae. Globally, the genus consists of about 600 species of vines and shrubs, which are widely distributed throughout the tropics and the subtropics. In Nepal, the genus comprises 15 species, which are distributed throughout the tropical, subtropical and temperate region of the country. Besides few enumerations and floristic surveys, no comprehensive anatomy and pollen characters of 16 species of Ipomoea occurring in Nepal to evaluate the qualitative and quantitative differences in these characters. We found that the all species of Ipomoea have paracytic type stomata. However, there is considerable variation in the size and frequency of the stomata. The size and shape of the epidermal cells also varies from species to species. Ipomoea nil has the highest stomatal frequency, while I. purpurea has the lowest frequency. All species of Ipomoea have globose, isopolar, echinate, pentoporate and radially symmetrical pollen grains. I. quamoclit has the largest pollen, while I. aquaticahas the smallest pollen. The anatomy of stem shows no distinct structural differences among species. Although no qualitative differences in the studied characters are found among species, there is considerable variation in the quantitative characters, such as the size of stomata, frequency of stomata and pollen size. These characters could have important taxonomic and ecological implications and therefore, are as valuable as the morphological characters.
Taxonomic study of Ipomoea cairica (L.) Sweet (Convolvulaceae)
International Journal of Technical Research & Science, 2017
Ipomoea is the largest genus in the flowering plant family Convolvulaceae, The most widespread common name is morning glories. The genus includes food crops; the tubers of sweet potatoes (Ipomoea batatas) and the leaves of water spinach (I. aquatica) are commercially important food items and have been for millennia. The water spinach (I. aquatica) commonly found in ponds, cultivated for stem and leaves used as vegetables. The study of Anatomical as well as morphological character is the key aspect of various Classification systems which is the basic unit of Taxonomy.

The genus Ipomoea L. is one of the genera dominated by climbing species exhibits diversified variations particularly in leaf and floral morphology among the species. A taxonomic study was conducted for the genus in the state of Arunachal Pradesh to evaluate diversity in their morphology and flowering phenology. The extensive field study and characterization revealed that the species of Ipomoea show a great morphological diversification particularly in terms of the foliar and floral characters. All the species found are with climbing habits and the leaves are greatly varied both in their shape and sizes. The flowers are of various colour and ephemeral in nature lasting only for 7 to 12 hours. Both inter and intra specific variations in the flower colour were observed. The corolla is mostly infundibular but in some campanulate corolla is also observed. The flowering seasons also vary among the species. Some bloom twice and others once in a year. These variations in morphological chara...
