We call this in Hindi “Nishoth”


I don’t think so


I am confused… THIS I DONT THINK SO is in response me….. that you did not see andy seedpods?
or is it to Balkar saying its called Noshoth in hindi?


Perhaps … disagree on identification of this plant…to me also this looks different from O. turpethum.. especially the leaves..


Pl.check for Convolvulus arvensis

Flowers of Ipomoea clarkei
Marathi name Sonpungali
At Kanakeshwar
26/09/2009

The original reference for Ipomoe clarkei, Flora of British India, describes I. clarkei as having ovate-lanceshaped leaves. Leaves are deeply heart-shaped at the base, with a long pointed tip. It does not say anything at all about the leaves being 3-lobed. Also the flowers are described as being more than 1 inch in size, larger than Ipomoea obscura flowers, which many people would have seen:
Flowers of India
(I sometimes get very irritated with botanists for not mentioning a simple thing like the color of the flower!)

…………………….

Coming to … flower, the leaves seem to agree with the description if I. clarkei quite well, but the flowers appear to be large. …, do you remember the approximate size of the flowers? The sepals of I. clarkei are supposed to be narrow, linear – a bud in … pic does show narrow linear sepals. I am very keen to know the identity of … flower – if it is indeed an Ipomoea, it would be the only yellow Ipomoea I know!


The flower size is aprox. 2 inches


If it is these yellow trumpet-shaped, flowers, which are part of the post, they look like Merremia umbellata

Should you ever have opportunity to take any clear closeups of the fully mature seeds, I am interested to correlate seed characteristics with plant morphology, even though others have been not yet been successful at this type of correlation.
I find that the seeds of M.umbellata subspecies umbellata are very consistent in seed characteristics and resultant plant morphology…same is true for M.umbellata subspecies orientalis and I am at a loss why others are unable to see the consistencies…

Check with Merremia umbellatum subsp. orientalis,


IPNI says it is synonym
Accepted name is Camonea pilosa
Correct me if it is wrong


Oh ! I thought it is Ipomoea sp.!!!


I think we should follow POWO as per details below:
POWO (Camonea umbellata (L.) A. R. Simões & Staples syn: Camonea bifida (Vahl) Raf.; Merremia umbellata (L.) Hallier f.)

Yes, it’s Merremia umbellata,


Thanks, ….

As per description of Merremia umbellata as per Convolvulaceae Unlimited
Inflorescence umbelliform cymes, few to many flowered ….
It further says:
Merremia umbellata can be recognized by its whitish puberulent axial parts, especially the pedicels; the crowded, umbelliform inflorescences (the secondary and tertiary branches short or none); the unequal sepals, with the outer two shorter, obovate, tapering to narrow bases between which the inner sepals are visible. Generally, the flowers of M. umbellata are smaller and there are more of them per inflorescence than in M. bambusetorum and M. kingii, though precise delimitation for these 3 species remains elusive.
It may be Operculina turpethum (L.) Silva Mansowith flowers solitary or cymose as per Flora of Pakistan (also see Flora of China).

Pl. confirm.


I think, you have a wrong notion of Operculina turpethum (L.) Silva Manso, …


May I request you to pl. post high resolution images to further check the details.



1 high res. image.



Any other images?

What are the species reported in your area?


Sir, sorry ! I don’t have other image. Stems of Operculina turpethum are often purplish, prominently 2-to4- angled, and narrowly winged.


By now it should be clear that this species can’t be Operculina turpethum – NO, NOT FOR THE STEM (though winged stem is an identifying character, but I will leave that part). The CAPSULE/ fruit in Operculina turpethum is “CIRCUMSCISSILE DEHISCENT”.

So, what this species can be is the million dollar question!
Is it Merremia umbellata (L.) Hallier f. (of eFI), which is based on  Ipomoea cymosa (Desr.) Roem. & Schult of “Flora of British India”?
There is no easy answer to this very question, because –
  1. Merremia umbellata (L.) Hallier f.  is now Camonea umbellata (L.) A.R.Simões & Staples
  2. Ipomoea cymosa (Desr.) Roem. & Schult  is now Camonea pilosa (Houtt.) A.R.Simões & Staples
…… more ???

Operculina turpethum (L.) Silva Manso ??


Yes …


Comonea umbellata ???


Please see that already ID !


It appears more closer to images at Operculina turpethum rather than those of Camonea umbellata as per POWO.


Yes, more proably it is Merremia umbellata subsp. macra (C.B.Clarke) Parmar = Camonea kingii (Prain) A.R.Simões & Staples, than Operculina turpethum.


As per description of Camonea kingii as per Convolvulaceae Unlimited
Inflorescence lax, a cymose panicle, usually 5–12-flowered ….
It does not appear so in the posted images. 


If this species is same as in efi thread, I think, it is never Operculina turpethum (L.) Silva Manso.


May I request you to pl. post high resolution images to further check the details.


The stems here look terete and smooth. Operculina has angled or winged stems.


This is not the same species as in the other thread, … posted – efi thread. Here flower is larger, peduncle is longer, flower is funnel shaped, unlike rather campanulate shape of Merremia.

And to my disappointment there is no fruit picture in the submitted set to prove my suggestion!
Another disappointment is that perhaps … is in no position to upload original plates of this species.
Moreover, Camonea kingii (Prain) A.R.Simões & Staples is not listed in Flora of Mizoram!
Should I accept Operculina turpethum then?
( I will skip the “winged stem” part! )
NO
  1. some of the peduncles are longer than 3 cm here
  2. anthers are different from Operculina turpethum (check the paper I mentioned in the other thread)
If … could show me a pair of tiny auricles at the petiole attachment site of the stem!!!
