Really Besharm ……….. Grows everywhere .. even in hardest conditions

Yes a Very common plant along ditches and field fencing.

Ipomoea carnea subsp. fistulosa is the only one observed in tropics. The other Ipomoea carnea subsp. carnea is distinct with cordate to rounded leaves is observed in central and south america

There is major difficulties concerning Ipomoea carnea subspecies fistulosa and Ipomoea carnea subspecies carnea.
I had researched the supposed differences in the ‘subspecies some years ago and found that there were significant misconceptions involved regarding the structure, location and behavior of the 2 supposed subspecies.
The only difference is in the shape (measurement parameters) of the leaves and plants conforming to the leaf parameters can be found in populations supposedly consisting of only 1 subspecies.
There are studies that indicate that other aspects like more vining or trailing habit for subspecies carnea has been shown to be dubious at best.
The fact that both subspecies were found to be able to adapt and therefore inhabit both arid and wet areas in both the New and Old world tropics has been shown to be true and that both subspecies can exhibit upright or more of a trailing (vining) habit based on topographical setting and adaptation, not any feature that is hard-coded into the genetics.
The information on the web from official sites concerning the subspecies is mostly related to subspecies fistulosa because that is what supports the old , antiquated studies…subspecies carnea is rarely located on the web, not because it is any rarer than fistulosa but because it doesn’t fit the old studies…
There is no difference in the seed characteristics of subspecies fistulosa or subspecies carnea.
The supposed differences were based on early studies that utilized under-sampling and did not embrace a wide enough area of topography.

I used to have all of the most important studies on my old hard drive but hardware self-destructed…although some of the more revealing studies were conducted in India (!)
The USDA and others responsible for perpetuating the myths related to the ‘subspecies’ will not back off without losing face and political agendas may apply…some co-author papers with Monsanto ( major chemical company that manufactures / sells most of the herbicides to fight invasive exotic plants, and as the list of invasive grows , so does the amount of toxic chemicals used to combat ‘invaders’) …my position is that the herbicides used do more long term damage to ecosystems than the over-growth of any plant species…enough said…
I would like to go on permanent record regarding my position on the myths related to the Ipomoea carnea subspecies and that the only difference is a relatively minor leaf measurement parameter and no other physical or behavioral characteristic.


I have recorded another member of Convolvulaceae today (27/Mar/2012), at NANO (in)famous SINGUR (Hooghly)!
I am sad that all the flowers lost their freshness during the mid-day when i reached there at around 2.30 pm.
Is it the same Ipomoea carnea subsp. fistulosa as in – efi thread ?
Species : UNKNOWN
Habit & Habitat : woody herb, height – 5 ft and above, wild in ditch beside railway track
Date : 27-03-2012, 2.30 p.m.
Place : Singur (Hooghly, WB)

Excellent views of the calyces , leaves and the colony.

Very nice, but this is a mid-atlantic to south american ipomea that at least in goats induces a cerebellar neuronal disorder leading to many symptoms including depression, diarrhoea, gait problems, etc… upto point can be reversed when removed from grazing on these plants…

Attaching another photo that i recorded this morning in my home.

Here is another photograph that i have recorded this morning in my home.

Living with this alien invasive species since decades Indian cattle and goats are well aware of its toxicity. They keep distance with it. Taking advantage of it farmers use it as fence.
In organic farming our farmers are using it for pest management.
I worked on its Allelopathic potential during post-graduation. Later using selected extracts and leachate for medicinal and aromatic crop production.
Natives have started using it in many forms like this one
Beautiful Tortoise beetles try to manage this plant but not much effective.
Oudhia, P. (2000). Studies on host specificity and preference of the metallic coloured Tortoise beetle (Aspidomorpha miliaris F.). Ecol. Env. And Cons.6(3):357-359.
Oudhia, P. Effects of leaf extracts on Metallic Coloured Tortoise beetle Aspidomorpha miliaris F..Insect Environment 5(4) : 165.
…, the problem with the studies you have mentioned is that in such experiments force feeding is done and observations are taken. In nature goats rely on so many species and no case of force feeding happens. Hence, such results are of academic interest only.

This ref : http://ecoport.org/ep?SearchType=pdb&PdbID=99279
shows a one time static photo….    did it sprout leaves and flowers?
did it flourish as a living hedge?

Yes, you are right. It acts as live fence in later stage.


Can the experts please help id this flowering reed that i found in water located in the shiwalik foothills to the north-west of chandigarh.

This is Ipomea carnea [locally called Besharam].

Please ID this ornamental climber (Convolvulaceae) with white flowers and pink centre. Photo was taken in Sri Lanka in Sep 2012.

It is Ipomoea carnea Jack. ssp. fistulosa (Mart. ex Choisy) Austin

Yes, a common shrub of wet borders..


common swamp plant for ID – Andhra Pradesh – 08022014-NAW2 : Attachments (2). 5 posts by 3 authors.

Kindly identify this common plant with pale pink flowers found in seasonal swamps and disturbed lands.
This was photographed on the 3rd of Feb near Markapur in Prakasham district, Andhra Pradesh.
The pictures are not very clear but i hope there is not so much difficulty.
height 1-2 metres. flowers 5-6 cm wide.
I was wondering if this plant could be used for greywater treatment.

Looks like Ipomea carnea.

yes it is Ipomoea carnea. A weed and sometimes invasive in wetlands

Thank you all for the identification.
i dont think this would be a good plant for greywater treatment – it being non-native and invasive would make management difficult and there is much mention of toxicity…

Can you consider Typha as a possiblity?
However Ipomea offers a good perching spot for cormorants and Whiskered terns and possible breeding sites for Purple moorhens , Eurasian Coot and the like. I do not know what could be a native replacement for Ipomoea. Maybe our esteemed teachers in our forum could suggest some alternatives.

The leaves you have posted are of different adjacent plant. Please check neatly. some other leaves are also seen here which belong to it.

Thank you very much … Yes, I will do so.

I fully agree with … the plant intended for id is Ipomoea carnea… and there is a mixing up..

Attached is a common plant that grows in any wet patch
​around central India​. They call it besharam or shameless in MP. Do you know the latin name and is it poisonous ? What sort of poison is it and how does it affect anyone ?

Thanks, … Pl. see Ipomoea carnea subsp. fistulosa for details.


Traditional Agricultural Knowledge: Chhattisgarh farmers still use extracts of Ipomoea carnea, Neem, Hyptis
to Cleistanthus collinus to manage rice pest.
It is part of their Traditional Agricultural Knowledge. I have uploaded a video based on discussion with Chhattisgarh farmer Shri Balak Ram. Please visit this link http://www.youtube.com/watch?v=cpjgA1dxhaE

Sunbird puncturing the Datura flower base and feeding on nectar:
Sunbird puncturing the Ipomoea carnea – morning glory family (?) flower base and feeding on nectar

9.30 am, 9 March, 2009 at Tailoor lake in Kokkare Bellur
This shrub is found in abundance all over the banks of the Tailoor lake (~300 acres).
The flower bud seems in no particular hurry to bloom but that does not seem to bother the purple sunbird. Well, remember the tale of the thirsty crow?
Even though the long tubes of the flower seem to be out of reach, the small bird displays enough intelligence to puncture the flower base and feed on the nectar happily and move on to the next plant.
Next time, anyone calls you a bird brain, take that as a compliment!
Ipomoea carnea Convolvulaceae (morning glory family)
(Tailoor lake is a paradise for wet land water birds – Coot, Cormorant, Spot billed duck, long legged stilt, Pelican, waders and numerous migratory birds)

The Sunbird picture is an eye opener for those who strongly advise removal of Ipomoea carnae from water bodies. They claim that this exotic is not visited by any bird and is harmful (?) to the wetland habitats. I have found that Ipomoea-Typha community creates floating masses of vegetation that supports a lot of aquatic flora and fauna.
It also offers the shelter and breeding sites to aquatic birds.
Recently all such ‘weeds’ were removed from a water body in Pune due to which the dwindling population of birds fell down to almost zero. Pistia that was in controlled proportion earlier now occupies the entire lake suggesting eutrophication.
I would like members to post their observations on these aspects.

Here is another one ..
Ipomoea carnea – morning glory family & Vespidae tropica (a large wasp)
Thailoor lake, Kokkare bellur, Mandya District, karnataka

Yes .., common in Delhi in marshy areas,

The wasp in the photograph is Vespa tropica belonging to family Vespidae.

Yes, the correct name of the wasp is Vespa tropica, Vespidae family. I have witnessed these wasps many times feeding alone. Probably a solitary wasp.

Not a solitary wasp but a social wasp. Check out my blog article at

Yes, these live together in a nest colony. Never witnessed them feeding on nectar together.

Yes … In central Indian n in North too we call it “Besharam” cauz it grows everywhere.

Besharam is really Besharam having presence everywhere….


Could your group of experts please help identify and describe this wild flower i photographed in the in foothills of chandigarh. These flowers are often found near wetlands.
I am writing about these flowers in the newspaper and would require your expertise.

Ipomoea carnea, familiy Convolvulaceae

Bush Morning glory
Marathi: Besharm
Hindi: Behaya

Leaves of this plant is being used in our area near Dussehra festival to grow Hordeum vulgare seeds (Barley). People when sow seeds in small pots , keep leaves of I. carnea on the soil. They think that these leaves help in early germination of seeds.
