Here is what I have for Ipomoea asarifolia
Ipomoea asarifolia
Perennial herb, much resembling I. pes-caprae
Stems prostrate or sometimes twining, thick, terete or angular.
Leaf lamina circular to reniform shaped, 3.5 – 7cm × 3.5 – 8.5 cm., rounded at the apex, sometimes emarginate, mucronulate, cordate at the base with rounded lobes, glabrous, subcoriaceous;
petiole 3.8 – 5 cm. long, rather thick with a deep longitudinal groove above, smooth or minutely muricated
inflorescences axillary, often together with an axillary leaf shoot, cymosely (usually) 1-few-flowered (although some strains appear to form clusters) ;
peduncle 2.5 cm. long;
pedicels 1 – 5.3 cm. long.
bracts ovate, minute;
Sepals unequal, all elliptic-oblong, obtuse, mucronulate; inner ones 8 -11 mm. long ; outer ones shorter, 5.8 mm. long, more or less muricate.
Corolla funnel-shaped, red-purple, up to 6.5 cm. long, glabrous.
Capsule globose, glabrous, as large as a pea.


I guess Ipomoea asarifolia do not match.

pls id this Creeper shot near Border of AP/Tamilnadu along road side. it was spreaded over there from dry area of roadside to low lying waterlogged area. During my visit to so many places in Chittoor Dist of AP and Chennai this plant was observed only at this place


I have an impression regarding the plant posted and it looks quite like Ipomoea asarifolia, of which the common name in English is Ginger-Leaf Morning Glory
Ipomoea asarifolia can have a variable leaf shape that can range from the rounded ginger-leaf share to the more somewhat pointy cordate.
The plant here could be Ipomoea asarifolia and the main aspect that causes me doubt is the structure of the peduncle as seen in photo 2147.
I hope my observations may help lead to a more definitive identification.

Ipomoea asarifolia can present as upright, semi-upright and / or as a trailer depending on genetic strain and local environmental conditions.


I think it may be of value to compare the plant in this thread with the unidentified Ipomoea in the following thread here efloraofindia:61534] Flora of Andaman30 – 100111-PKA1
