This seems to be I. marginata but purple blotches on leaf are missing.

Dear Shrikant Ji,
It does looks like I. marginata except for  the purple blotches on the leaf  which i could not spot. If i remember correctly, Dinesh has also seen this some where in Thane region.
regards
Prashant

... yes, as said by Prashant, this plant grows in few locations in my neighbourhood.
A feature of I. marginata that is normally seen is ... the flower is almost never solitary ... it is accompanied by at least another bud or two.
Also this plant has its leaf and flower slightly larger to those of I. marginata.

Regards.

Hi Prashant and Dinesh,

Blotches on leaves, flower size or number of flowers are not the key
characters for I. marginata. Sepals obtuse, corolla hypocrateriform
and seeds with long hairs are the key characters. In the present
situation it looks to be I. marginata unless you find anything
contarary. Regards, Shrikant

Hello,

I think the plant in question is likely to be Ipomoea marginata ,
although I have some reservations.

Ipomoea marginata may have hairs on the leaves and stems or it may be
glabrous.

The leaf shape may be cordate or can vary to an almost sagittate
shape.

The purple blotches are not a requirement and are likely a response to
intense sunlight or other environmental factors.

I do see a difference in the coloration in the tube and throat which I
see as atypical in addition to a difference in the length and taper of
the tube.

The corolla measurements and tube characteristics are always important
whether mentioned as a key characteristic by any author or not...some
contemplation on this might be in order...

I also notice that the petiole on this plant has some stoloniferous
protrusions ( most visible in the 4th photo ) that are worthy of
notice and are not often seen in photos Ipomoea marginata.

Hope my observations may be of some value...

regards,

Ron

It is nice to read detailed responses from you. It surely enriches our knowledge.
