Thanks Gurcharan ji, for your detailed reply. So, Ipomoea nil it is. I did not know about the feature that the upper part of the sepals is hairless - the following illustration then protrays it incorrectly: http://malherbologie.cirad.fr/Advenrun/especes/i/iponi/dessin_iponi.html Rather I interpreted it incorrectly as sepals being overall hairy. Regarding putting up photographs by different people for the same species (at FOI), there is a reason behind it. Some species show variation in leaves and colors. For example, in some parts, Ipomoea indica has heart-shaped leaves, and is some parts, the leaves are strongly lobed. Another example is Kydia calycina, where even the flower color varies: http://www.flowersofindia.net/catalog/slides/Kydia.html I feel, putting up pictures of the same species from different parts of the country helps, unless of course something has been misidentified. Best wishes - Tabish
