Title: Plant identification - Assam/Bhutan
Post by: Julia on November 28, 2013, 09:08:41 PM: Hi can anyone help identify this lovely white flower from low country in Assam on the way to Bhutan :)

Post by: Maggi Young on November 29, 2013, 12:43:56 AM: Is it growing down a bank?

I wonder if it is some kind of Polygonatum, Julia? In which case we need the advice of Aaron Floden.......

someone let me know that it is Pentasacme wallichi. You can find it in "Flowers of the Himalaya, A supplement" by Oleg Polunin.

Seems Edinburgh has a herbarium specimen, Julia, which may be of help to you

Edit:
I should have added - it's in the Asclepiadaceae - the Milkweed family.

Post by: Afloden on November 29, 2013, 01:42:13 PM: A friend saw this in Arunachal in September and sent me images of this. I had thought Cynanchum originally, but he found the Pentachasme ID as well. Probably the same person as the one who let Wim know.

A very attractive plant! I hope to see it next spring while looking for Polygonatum.
