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
