King's-mantle

thanks Vincent, Ashish and Chief RedEarth for your input into this spotting... Still looking for a definitive ID for this plant, though.

Pamela if you able to find more species in Thunbergiaceae family...
Like Meyenia hawtayneana

Hmm, just checked the Flowers of India website. This spotting is a small bush growing all by itself in the garden, no vines nearby! And the leaves look different, I think. I'll check them tomorrow in my garden. Thanks Ashish...

Vincent many climbers are mixed with shrubs and big herbs and make you feel flowers of host(supporting of climber) plant. I felt such in many species... Flowers of India website is really a helping and Books of Proff. Shrikant Ingalhalikar... are too.

@Ashish. Thanks. Definitely not Laurel Clock Vine as it grows on a bush and the flowers don't cascade down as they do on Laurel Clock Vine.
I think this other spotting is Laurel Clock Vine, the flowers look identical to the vine in my garden.

Perhaps this spotting is King's Mantle. The flowers don't grow in clusters.

Pamela I have suggested 2 matching species... Verify yourself which match with your spotted flower structure specially in Petals and Sepals....

thanks Chief RedEarth, but this is different from Bengal Clock Vine http://www.projectnoah.org/spottings/170...
It grows on a small lanky bush, not a vine, and the flowers look quite different in shape and colour.

Dear Chief RedEarth, This is not a vine. It is a bush-type plant seen in plenty here in Palakkad, Kerala.
