Ipomoea coccinea has reflexed fruit
Ipomoea hederifolia has erect fruit

The most important feature to capture for Ipomoea hederifolia to differentiate from Ipomoea coccinea is the calyx of the fruit in various stages... The leaves on both Ipomoea hederifolia and Ipomoea coccinea can mimic each other (I know because I have grown enough of them myself) but the pedicels of Ipomoea hederifolia always remain erect while the pedicels of Ipomoea coccinea reflex...
So, in my experience trying to differentiate Ipomoea hederifolia from Ipomoea coccinea using any other part except the calyx and pedicel will lead you astray...

This plant has the tendency of spreading, and growing gregariously in the wild, profuse flowering attracts us from far distances. 
the color size, habit of looking up or out by the flower face, and buds standing erect are also seen in Ipomoea quamocilt  ... except there the leaves look like little centepedes and here the leaves are heart shaped...

Could not locate this a botanically acceptable name under I. hederifolia.
Yes ... There is no mention of such species in most of the taxonomic sites.
The posted plant looks similar to what
Dave's Garden has. A go-to site for me for finding garden flora.
Many thanks ... for pointing to the possibility of Ipomoea lutea.
But the flower tube in illustration seems relatively larger.
If there is no such name, then the posted plant could be just a variation in colour of flowers, and may well be Ipomoea hederifolia.
Let us wait for comments.
Ipomoea hederifolia corolla may be yellow, orange or crimson ... Leaf is a 'key' feature.
Many thanks ... What are your thoughts about Ipomoea hederifolia var. lutea ?
Is it possible to know from the leaf seen in this view (of the posted plant) ?
You have clearly mentioned in your initial post that the name Ipomoea hederifolia var. lutea does not appear in ars-grin and the plant list databases but appears in some other sites.
I am not a taxonomist ... and thus would like to reserve my comments on your specific question [ie. What are your thoughts about Ipomoea hederifolia var. lutea ?]
With regard to your other query [Is it possible to know from the leaf seen in this view (of the posted plant) ?] I feel the plant is Ipomoea hederifolia L. 
I will share my experience regarding the binomials, epithets  and associated 'subtaxa'.
The plant you have posted is indeed Ipomoea hederifolia and despite some hesitation expressed by some other members in the past as to whether dilute color forms exist, I will say that I am aware of dilute color forms existing within wild populations in both the New and Old World.
The addition of the subtaxa 'lutea' and sometimes 'aurantia' , although not official was used by some growers and merchants in an attempt to give credence to the dilute color forms (even though not yet officially recognized) rather than use a description like "my favorite yellow or orange dilute form". The usage of the lower taxonomic rank terms like vaiety and forma has to start someplace and I do not believe that it is only 'official' taxonomist who should be allowed to institute the usage of taxonomically correct terms.
I supported the usage of recognized taxonomic terms rather than non-taxonomic terms because I thought it would be best in the long term regarding organizing some wild variants.
Ipomoea lutea is a distinct and separate species from either Ipomoea hederifolia, Ipomoea coccinea or Ipomoea cristulata.
There was some substantial confusion created when a marketing firm in Australia ( about 10 years ago) began to market seeds that they were calling Ipomoea luteola (which is a synonym for Ipomoea hederifolia and used mostly in Australia) but the company actually distributed Ipomoea coccinea causing confusion amongst the Morning Glory appreciation community and I am glad to have the opportunity to try and clarify the matter.
There is also a dilute form of Ipomoea cristulata that occurs in New Mexico but that has not yet been given any official recognition or marketing terms.
I hope that my experience helps to clarify the matter...

P.S. When I suggested the usage of taxonomic ranks of variety and forma be used in place of silly marketing terms,  I also always was sure to emphasize  placing the 'new subtaxa' in single quotation marks to indicate that the terms were not (yet) officially recognized , but merchandisers did not strictly follow my advice and so therefore Ipomoea hederifolia var. lutea appears instead of Ipomoea hederifolia var.'lutea' and so on...

Many thanks ... for providing clarity in this regard.
Thus, this plant may very well be just Ipomoea hederifolia; OR Ipomoea hederifolia var. 'lutea'.

Ipomoea hederifolia family Convolvulaceae
In Marathi commonly called it as Ganeshvel
The salverform corolla is nicely captured.
It would be useful if you can share more photographs of leaves. Yellow corolla throat and few leaves seen being unlobed suggests this to be I. rubriflora (syn: I. coccinea).
The most important feature to capture for Ipomoea hederifolia to differentiate from Ipomoea coccinea is the calyx of the fruit in various stages...
The leaves on both Ipomoea hederifolia and Ipomoea coccinea can mimic each other (I know because I have grown enough of them myself) but the pedicels of Ipomoea hederifolia always remain erect while the pedicels of Ipomoea coccinea reflex...
So, in my experience trying to differentiate Ipomoea hederifolia from Ipomoea coccinea using any other part except the calyx and pedicel will lead you astray...
Thanks for the observations and your experience with the Convolvulaceae plants not only in this but other species too. Members will certainly remember the points to look for in identifying diff. species.

i don't see any lobed leaves and yellow throat is very prominent. This is what Hortus Third reprts:
I. hederifolia is often confused with I. coccinea but having always leaves lobed. Here is brief difference;
I. coccinea: leaves cordate-ovate, to 15 cm long, entire or coarsely dentate; corolla scarlet with yellow throat, to 4 cm long; fruiting pedicel deflexed.
I. hederifolia: leaves 3-5 lobed, middle lobe ovate-lanceolate, lateral lobes narrower, corolla scarlet, tubular.
Many many thanks ... for validating the post, and for the differences among the two close species.
I remember you having put it earlier. But it did not strike me to check for these differences in my sightings.
Now clearly seeing the yellow-throated flowers in:
Jan 14, 2007 ... at Powai, Mumbai

-- So these must be Ipomoea coccinea.
Let me attach cropped versions of the plant seen on Nov 3, 2007 ... at Kharghar Hills, Navi Mumbai.
They seems to have no yellow throat, and the leaves too are lobed.
These may be Ipomoea hederifolia; please validate.

Yes ..., great analysis.
Thanks for showing us both species.
I have grown many strains of both Ipomoea hederifolia and Ipomoea coccinea from different parts of the world and here is my firm conclusion.
The flower and leaf form may vary considerably in both of the species in question, so do not be fooled into attempting to Identify by either the corolla or the leaves...but , the calyx and more importantly the behavior of the pedicel is THE most important aspect to consider and I see erect pedicels in this set of  photos.
My conclusion is the plants shown here are Ipomoea hederifolia.
Please be aware that the references and keys are most often written by people working in the field where precise measurements and clear closeup photographs of all relevant parts and at all stages of growth is rarely possible., so the keys of yesterday are somewhat obviated by the macro-photography of the computer age...
The people who wrote many of the keys never actually grew the plants (or studied them every single day watching very closely every single development of the parts at all stages of growth) but they were often forced to do what they could in the form of taking quick notes in the field as they moved on to the next series of plants they hoped to get to...quantity of information often took priority over quality and line drawing were what was possible long before before small digital cameras.

I hope that my observations and thoughts may ultimately prove to be of value,
You are surely a great expert of Convolvulaceae, and we would surely like to be guided by you. It is really fortunate that you have found time to interact during Convolulaceae week. It would help us all if you could kindly list the diagnostic differences between I. hederifolia and I. coccinea (and your opinion on whether you agree with The Plant List as synonym of I. rubriflora).
Thank you for appreciating whatever I have to share but I never refer to myself as an expert but as a 'constantly aspiring aficionado' and that is not false modesty...knowledge is a reverse pyramid (which raises more questions with each answer "The more you know , the more you realize that you don't know")  and in that regard there are no 'experts' but only 'constantly aspiring aficionados'.
I am glad to share (and guide ) relative to what I am aware of but my knowledge is far from complete and never will be...
The main difference between Ipomoea coccinea and Ipomoea hederifolia is the calyx and the pedicel which I shared in the PlantFiles (when I was still a member of that site)
Here are some links
Ipomoea coccinea - reflexed pedicels
Ipomoea hederifolia - pedicels remain erect
read the lower portion in English (I use google to translate into Spanish) where I address the awn and arista
The Tropicos site lists Ipomoea coccinera L (which should indicate legitimate) as having 3 accepted names...
Ipomoea coccinea
Ipomoea coccinea - perform your own search because searches cannot be saved in url
Ipomoea rubriflora perform your own search because searches cannot be saved in url
Ipomoea rubriflora - lists Ipomoea coccinea as a synonym
I think it is confusing to have Ipoomoea coccinea listed as a legitimate species by both Ars-Grin and Tropicos and at the same time have Ipomoea coccinea L. listed as a synonym of Ipomoea rubrifloa.
The PlantList may or may not be 'correct' on Ipomoea rubriflora since this particular case is confusing in comparison to the other reference sites...so, who can know for sure at this point (?!)
There are often times when someone doing field research will need to insure/ preserve their funding and so minor differences which (from my perspective) may warrant a rank of subspecies , variety or forma , get assigned to the rank of a 'new species' (!)...and the 'discoverer' who is the only one who knows the exact location, continues to receive additional funding to continue to study the new species, which sometimes never truly sees the full light of day...and I have seen this 'phenomenon' occur too frequently...
Ipomoea species rarely cross the species barrier (with rare exception , e.g., within series batatas), although subspecies and lower taxonomic ranks will cross fertilize, so when I am in doubt, I try to obtain germplasm and perform my own crossings to get a 2nd opinion from the plants because the plants surely know the degree of relationship between themselves better than our human visual observations.
I am fully aware that various degrees of compatibility and incompatibility exist within species and sometimes even lower taxonomic ranks, but if the supposedly different species cross fertilize, then they are in all likelihood not different species at all...the plants do not lie...
I will believe that Ipomoea rubriflora exists when I see closeups of the relevant structures that differentiate it from Ipomoea coccinea and until that occurs I will be skeptical of Ipomoea rubriflora.
I hope my contributions will prove to be of value.
I think this plant was discussed earlier also. I. hederifolia has distinctly lobed leaves and corolla not yellow in throat. This should be I. coccinea. Please see the two revised uploads of ....
Please see this upload by ... also efi thread

I. coccinea is now correctly known as I. rubriflora.
This is an unusual version of what I think is Ipomoea hederifolia.
The pedicels are not truly reflexing but are facing downward because the entire peduncle is arching downward as can be seen here
The elongated tip to the sepals are more consistent with Ipomoea hederifolia than Ipomoea coccinea, although, ideally I would still like to see what the still green but almost ripened fruit looks like...

The 2nd and 3rd photos clearly show fully erect seedpod pedicels and I surely agree with ... that the species shown is Ipomoea hederifolia.
P.S. - I cautioned about not using the leaves for Identification because they can vary and mimicry of other species occurs ,but the pedicels are the most accurate.

Perhaps some one will have to sort this out
The species identified as Ipomoea coccinea may belong to any of these two species
Ipomoea coccinea L. is now correctly known as Ipomoea rubriflora O'Donell
Ipomoea coocinea Seese & Moc is now correctly known as species Ipomoea hederifolia L.
The two are very closely related, perhaps separated by minor characters. I saw a note by Ron_convolvulaceae on these. May be he or any other member can sort this out.
How I. cholulensis is different?
i guess photo posted here is Ipomoea hederifolia, in Maharashtra we dont get I. coccinea L. in Wild i guess, may be present, also I. coccinea L. corolla tube inside is yellow in colour, whereas I. hederifolia is totally red..
This is what Hortus Third writes:
I. hederifolia is often confused with I. coccinea but having always leaves lobed. Here is brief difference;
I. coccinea: leaves cordate-ovate, to 15 cm long, entire or coarsely dentate; corolla scarlet with yellow throat, to 4 cm long; fruiting pedicel deflexed.

Comment please.
And these are two of mine pictures from the place showing corolla mouth and cordate leaves. Hence, this is closer to I. coccinea

Many thanks ... and ... for this key.
The Plant list treats Ipomoea coccinea L. as the synonym of Ipomoea rubriflora O'Donell.

P.S. Cant attach the whole PDF file...therefore sending a snapshot copy. Full PDF can be downloaded from the following link:
Comments plz.
Requesting you to reconsider my points.....
According to the key provided above, I. rubrifolia (=I. coccina) is characterized by the presence of yellow neck and ovate-cordate leaves. But in the PDF file attached above, the plant shows yellow neck and lobed leaves. This is creating confusion for me.
Attaching some more pictures for your perusal.
Please read it as I. rubriflora
It is really confusing. May be species identified as I. rubriflora in the pdf is not correct. The two species I. coccinea (now rubriflora) and I. hederifolia really close only leaves (plus few minor characters) seem to be differentiating them.
And interestingly....Flora of Korea reports I. hederifolia as the cultivated species in Korea. There is no mention of I. coccina or I. rubriflora. Another Korean weed-flora mentions I. cholulensis with the photo of similar looking plant.
The above fotos were taken at Daejeon, S. Korea.
Yes ... Your plant seems true I. coccinea (=I. rubriflora), but then there is lot of confusion in literature especially on the net.
Photographs of I. hederifolia L. shared by ... in the following thread clearly shows lobed leaves and scarlet flowers without yellow throat. This helped me to clear my doubt.
I am really thankful to you for providing a nice key that helped me to understand these plants. Now I can confirm my plant as I. rubriflora O'Donell (=I. coccinea L.).
I would also like to refer a paper that proves these taxa distinct based on molecular data.
Here is the link :
Unfortunately, ambiguity can still be seen in 'Tropicos' that treats I. hederifolia L. as the accepted name for I. coccinea L.
I think Tropicos simply lists treatment by different publications.
Perhaps this paper from Taxon may help

Uploading photographs from near Dakpathar.

I have found those who quote Hortus to be mistaken on many Ipomoea species which require a wider knowledge (first hand is best) of the variations that do occur within the referenced species. 
I believe Hortus to be somewhat 'antiquated' and obviated by more modern references which are more frequently updated and frankly I rarely reference it on Ipomoea as many updates have taken place since Hortus Third.
This instance Ipomoea coccinea is reduced to synonym status and equated with Ipomoea rubriflora and as I had referenced in another thread on the subject of these epithets , even the current online references seem to be 'fuzzy' regarding the status of Ipomoea rubriflora and the relation to Ipomoea coccinea.
There is only 1 ( not 'several' ) Internationally accepted legitimate name usually presented at International Botanical Congress...
I suggest that at this point in time and space that Hortus Third be used with requisite grains of salt...
