Identification of Ipomoea sp. : 16 posts by 4 authors. Attachments (4)
Pl help me to identify the attached specimen of Ipomoea, a slender creeper found near Karaikudi, Tamilnadu. It was trailing on the ground.
Does not seem to match with any species in efi as per comparative images at Ipomoea
We needs the dimensions of the flower
As the place is far away from my residence, require one night travel, I will try to provide the details in due course.
Could it be Rivea ornata?!
Thank you …
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.
Any Rivea species (wild) ?
The flowers resemble Rivea hypocrateriformis flowers. Hence it could be a Rive species (wild) ?
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.
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 :
Many thanks for your opinion on the ID of this plant. I appreciate your kind response!
When … 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.
Characters of Ipomoea pes-caprae subsp. brasiliensis do not tally completely.The flowers do resemble Rivea.
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.
