Cynanchum callialatum

Cynanchum callialata: Mulshi near Pune: I found this Asclepiadaceae climber in Sep 2012 on road towards Lavasa.
After carefully observing the pictures I think this is Cynanchum callialata.
Ref FOS By Shrikantji.
Tall climber with opposite leaves. Flowers tiny(Less than a cm) in umbellate cymes.
It was a surprise for me when members visiting VOF were showing different Cynanchum species. I could find this one from Western ghats

Flora Picture of The Year 2012 : Dr. Satish Phadke: Cyananchum callialatum
I get fascinated by the radial symmetry and the geometry present in flowers of most of the species of Asclepiadaceae.
It was a joy for me when I came across this species in Mulshi area on way to Lavasa .
It is a climber with tiny flowers of less than a cm.
I could find the ID from the book Flowers of Sahyadri. I posted the pictures on the group when VOF week was going on in full swing.
On searching the Efloraofindia I was surprised to know that this species was not shared by anybody so far.
I was disappointed that nobody took notice of the post.
Presenting my Flora Picture of The Year 2013.

Apocynaceae?

---

Pl. check comparative images at Apocynaceae

---

Closest I can reach is some Cynanchum species as per comparative images.

---

Agreed, …

But, species level identification is difficult. because of data conflict !!! for example –

1. POWO
2. http://flora-peninsula-indica.ces.iisc.ac.in/herbsheet.php?id=1254&cat=7
3. https://sites.google.com/site/efloraofindia/species/a—l/a/apocynaceae/cynanchum/cynanchum-callialatum
4. Plant illustrations

So, please consult local flora guide.

I will go with Cynanchum callialatum

Leaves appears to be quite variable as per GBIF specimens from India.

CoL treats Cynanchum tunicatum (Retz.) Alston as a syn. of Vincetoxicum callialatum (Buchanan-Hamilton ex Wight) Kuntze (syn: Cynanchum callialatum Buch.-Ham. ex Wight)
However, POWO treats them as different with only, Cynanchum callialatum Buch.-Ham. ex Wight having distribution in Bangladesh.

Thanks for the update, Sir ji.

However, there is another species in Bangladesh, in which leaves are more cordate – http://apps.kew.org/herbcat/getImage.do?imageBarcode=K000894620
