Identification of Ipomoea sp.

[S Kasim .]

Dear all.

Pl help me to identify the attached specimen of Ipomoea, a slender creeper  found near Karaikudi, Tamilnadu. It was trailing on the ground. 

My suggestion is Ipomoea repens or Ipomoea asarifolia.

Thanks.

With kind regards.

Could it be Rivea ornata?!

Thank you Dr. Vijayasankar Raman.

1. The plant observed is not an erect undershrub or shrub and the branchlets are not white tomentose. But it is like a (prostrate) climber with long internodes and tendency of rooting at the nodes.

2. The Peduncle is longer than the petiole.

I attach the specimen in high resolution which will help to examine the parts by zooming.

The flowers resemble Rivea hypocrateriformis flowers .   Hence  it could be a   Rivea  species (wild)   ?

Dear sir , 
I beg to disagree again . 

Rivea hypocrateriformis flowers are having long and narrow corolla tube , narrow throat and sudden flaring of limb . 

Here the case is opposite . 
Can it be Ipomoea pes-caprae subsp. brasiliensis ?

I base this guess on two facts ..........

.......subsp. brasiliensis is said to have leaves only slightly notched and not deeply lobed . 
And , Ipomoea pes-caprae does have white variants , or , rather flower color varies from white to deep pink and in between .

Also , variation in leaf bearing and leaf morphology is a strong characteristic of this species .   

With regards , 

Rakesh .

Ron,

Many thanks for your opinion on the ID of this plant. I appreciate your kind response!

@ Kasim ji,

Ron Kushner thinks that your plant could be Ipomoea asarifolia as also suggested by you. Below you will find his assessment and opinion.

--------------------------

"Hello ,

I have examined the photos and my impression is that the plant is either Ipomoea pes-caprae or Ipomoea asarifolia, although I am leaning towards the latter of the 2.

The measurements of Ipomoea pes-caprae and Ipomoea asarifolia in various treatments are almost identical with the exacerbation of the length of the peduncle which can be :

I.asarifolia  - 2-5.5 cm / 1 to 2 inch or 1 to 4 inches - depending on treatment
I.pes-caprae  - 4-14cm 1.5 to 7.5 inch

Can any of the viewers  determine the exact length of the peduncle by viewing the photo...I am unable to...

The sepals of Ipomoea asarifolia are noted for being warty , typically more so than what would be seen n Ipomoea pes-caprae, and the sepals on the plant look more warty than not to my eye...

The leaf shape could also match either I.asarifolia or I.pes-caprae, although in my personal reference files , I have more examples of I.asarifolia with the type of leaf shape displayed on the plant in question and I do have examples from various areas of the New and Old World...

The seeds are of course smooth and smaller in I.asarifolia as compared to I.pes-caprae which are always very tomentose, although we do not have the luxury of that feature available to us at this point in time.

So, the location of the plant is the last factor which tends to support an ID of Ipomoea asarifolia because of the inland location, since Ipomoea pes-caprae is almost always located just above the high tide line and only rarely found far from the salt-water shore...

My assessment is Ipomoea asarifolia, although I would welcome any input and / or evidence to the contrary.

regards,

Ron Kushner"

[dr.rakesh Singh]

Good Morning all of you ! 
When S Kasim Sir had posted these photos in Indian Flora FB group , I had suggested I. asarifolia as a possibility , along with I. imperati . Further perusal on the ID led me to consider about I. pes-caprae subsp. brasiliensis . 
Only point I want to highlight here is , I am observing in few places Ipomoea pes-caprae  being used by gardeners in Urban landscaping in private homes and there growth is vigorous  ...........typically , they make it climb on roof of barn shades . I'll not be surprised if I encounter an escapee  .
With regards 
Rakesh .

Characters of  Ipomoea pes-caprae subsp. brasiliensis  do not tally completely .   The flowers do resemble Rivea.

Sorry I posted the  reply just now without seeing the post sent by Vijayasankar ji. It could be  even  Ipomoea asarifolia .

Thanks to all for having participated in the identification.

If possible I will try to furnish the dimensions of the various parts, in due course. 

with regards.
