I was considering this plant to be Ipomoea batatas , now I do not why !!


... click on photo for more views

The flower is about 2.5 - 3 cm; the leaves are typically as seen in this photo, however there are cordate leaves like we see in one of other views.
Another observation is the leaves often have some grey or dark irregular patches near the petiole and midrib.

Habitat: Estuarine scrub

Looks like Ipomoea marginata, which has the following features:
Corolla white or purple, with a darker center, salverform (narrow tube suddenly flaring into a flat flower), 2.5-4 cm.

Leaf blade often purple or purple spotted, elliptic-ovate or reniform to circular, apical leaves sometimes sagittate or hastate
